The most crucial part of a Tesla is the battery. One advantage Tesla has over the competition is their excellent battery regulation. Batteries in a Tesla last longer when compared to the competition due to Tesla’s excellent battery monitoring.
There are four major contributors that lead to lithium-ion battery degradation, which we would like to minimize. The first two we don’t have much control over, which are the age of the battery and the number of charge cycles (the number of times the battery has been charged and discharged).
However, the last two, we do have control over. Lithium-ion batteries don’t like to remain in a very high, or very low state of charge. That doesn’t mean we should never charge to 100% or use it down to 5%, but it’d be wise to minimize those occurrences. The last thing is the temperature of the battery. For the most part, Tesla handles this automatically. The batteries are heated and cooled to stay in a healthy temperature range without you ever knowing, even if the car is off. The car will also limit power when driving if necessary.
If you’re going on vacation and leaving your car at home or at the airport here are some things to consider.
If you can leave your car plugged in while at home or the airport
If you can leave your car charging, then absolutely do this, this will make things much easier and let the car control everything itself without you ever having to worry about it
Lithium-ion batteries are best stored at around 50% of charge, so set your charge level in the Tesla app or the car to 50%. The car will automatically use some energy when needed to cool or heat the battery, and it’ll get this power directly from the power source instead of Tesla’s batteries.
Keep the car in a garage or under a cover if possible, this will help keep your car away from extreme elements such as snow, ice and heat. In general, this is just good practice.
If you can not leave your car plugged in at home or the airport
If you can not leave your car plugged in while going on vacation there are several more things we need to account for to prevent any possible issues longer term.
If the weather is extreme, whether it’s extremely cold or hot and you can not park in an isolated area and are going away for more than two weeks, then you may want to consider a different mode of transportation. If the car battery is drained completely, it could lead to battery damage since the car can no longer keep the batteries at an ideal temperature and it’ll no longer be able to protect itself from harsh weather.
If you're going to be gone more than a few days, try to have your car charged to 90% as it will consume some energy as it's parked. If you're only leaving for a day or two, then a 70 - 80% charge should be more than fine.
Since your car will be unplugged and unable to charge, you can help preserve the battery by turning off Sentry Mode if it won’t be needed as this consumes quite a bit of energy.
You will also want to turn off Stand By Mode in the Autopilot menu. Standy By Mode keeps your car's computer on so that you have instant access to features such as Summon. However, it does use additional energy.
To further preserve the car's battery, you can turn off Cabin overheat protection, which is used to keep the cabin from overheating. The car attempts to keep the cabin below 105°F.
Keep the car away from harsh weather, if it's winter then keeping it in a parking garage and away from wind will help. If it's the dead of summer, then also try to keep it under a covered area in the shade if possible.
If you’d like to check in on your car, it will need to have a good cellular connection.
Before leaving, confirm that the car has a good connection so that you can check on the battery level if needed. However, do not open up the Tesla app often, as doing so will wake up the car and keep it awake for about 15 minutes, consuming more energy. Only check on the car if you absolutely need to.
Keep in mind the amount of charge you’ll need in your car when heading back home or reaching your first charging destination. If you’re leaving your car plugged in, then you can expect the car to remain at the same charge percentage if there are no power outages. However, if the car is not plugged in, it may have a significantly less charge when you return.
As you can tell, it will be much easier and safer if you’re able to leave your car plugged in while going on vacation, especially if it’s for an extended period of time.
If you plan to store your Tesla for longer periods of time, you should find a place to keep your Tesla plugged in and follow the “if you can leave your car plugged in” tips above.

In case you missed Tesla’s Q1 2025 earnings call last night, or just want to see the cliff notes, we’ve got you fully covered. While Tesla called this event a “Company Update” on their Investor Relations website, we covered all the usual aspects of a regular earnings call.
Tesla had a rough Q1, but managed to pull through even in the face of one of the most financially difficult quarters in recent memory. There’s also a lot of exciting news as Tesla shared updates and key information on some of its upcoming products.
Tesla actually started this event relatively on time, with the call beginning just seven minutes after the scheduled start time. If you prefer to listen to the call, you can listen below with the call starting at the 7 minute, 9 second mark.
FSD Supervised & Unsupervised
FSD Supervised launched in China, received positive reception.
Tesla launched FSD in China without access to country-specific data, and it is performing extremely well.
They expect this will make it easier to launch elsewhere.
FSD Supervised for Europe still on track for 2025.
FSD Unsupervised is now running Model 3, Model Y, and Cybertrucks from the production line to the outbound logistics lots at Fremont and Giga texas.
As of this quarter, FSD has been driving people in North America and China for 7.7 Million miles per day.
Tesla will consider pricing options for Unsupervised FSD vs Supervised FSD
In the meantime, Tesla plans to gradually lighten the supervision requirements
Executive team believes FSD is too cheap at $99/mo as it currently stands
Glare, Sand, Dust, Fog
Cameras are not fully blinded by glare or other obstacles
Tesla’s photon-count analysis happens before digital signal processing - the image you see on the dash may be washed out, but FSD can see fine.
Snow and Inclement Weather
These are still a challenge for scaling out to areas that experience snow.
Tesla is looking at implementing localized parameters to deal with snow or other localized conditions in the future
Not essential, but a “nice-to-have”
These parameters will be focused on improving reliability for certain tasks, like driving in snow
Waymo
Tesla doesn’t see Waymo as a challenger
LIDAR is expensive, can’t solve many problems
Pure vision is the key (along with audio now)
Tesla isn’t just doing a software solution and attaching hardware to a pre-existing vehicle, Tesla is building the vehicles ground-up with autonomy in mind
Validation is still a challenge, due to edge cases.
QA fleet is driving in Austin, and can go many days without an intervention
Difficult to tell whether improving or regressing
Deeper and broader simulation systems are being built
Seeing an intervention every 10,000 miles means they need 10,000 miles of data on average to address it
Need as much data as possible - 10,000 miles is the average distance covered by a driver in North America in a year
The executive team noted that Chinese FSD testers are doing a fantastic job testing edge cases
Unsupervised FSD & Robotaxi Fleet
Tesla is on track for the pilot launch of Robotaxi in Austin for June 2025.
These will move the financial needle in the 2nd half of 2026.
The first vehicles will be Model Y’s, not Cybercabs.
Aim is to start in Austin and roll out elsewhere in the United States by the end of the year
Focus is to ramp quickly, and have millions of vehicles operating autonomously by the end of 2026.
Remote Support for robotaxi fleet could happen, not 100%
10-20 vehicles on Day 1 for Robotaxi fleet
Scale-up will happen slowly
By the end of June or early July, anyone will be able to go to Austin and use a robotaxi
Vast majority of Tesla’s existing fleet will be capable of Unsupervised FSD
Elon specifically mentioned the Model S, 3, X, and Y
This is the fourth event (We, Robot, Q4 Earnings 2024, All-Hands, and Q1 Earnings 2025) without mention of the Cybertruck being capable, likely meaning that FSD development for the Cybertruck is further behind as we’ve seen.
Tesla’s generalized solution to autonomy means that once they verify it works in a few North American locations, it should work in any North American city
Key limitation is regulatory approvals
This also applies for other areas of the world - the generalized solution will make it easy to apply it elsewhere
Tesla is providing autonomous supervised vehicles today that are capable of:
Cutting commute effort
Improving lives for customers with disabilities
Tesla’s executive team wants to get these stories out and get people to experience FSD
Unsupervised FSD should launch for customers in the US, ideally by end of year
Safety is a key concern, Tesla needs to continue reducing interventions per mile
Tesla will be careful with rolling this out outside of dedicated fleets
It must be meaningfully (10x or more, as per Q4 2024) safer than a human
Will likely be geofenced to specific cities or locations
Elon expects the first Model Y will drive itself from Fremont or Giga Texas all the way to a customer by the end of 2025
Affordable Vehicle
The plan for the new more affordable model (identified as a new vehicle), remains on schedule for production beginning in the first half of 2025.
These will utilize aspects of the next-generation platform as well as current platforms, and be produced on the same manufacturing lines as current vehicles.
This approach will result in less cost reduction, but will enable Tesla to manage capital expenditures.
This model will start production as soon as June and be in the market shortly thereafter.
Ramping will be slower than hoped due to global tariff and financial impacts
Production timeline is still on track overall
Tesla is aiming for a lower initial cost of ownership and lower monthly payments
Tesla will use its existing lines - reducing the overall form factor difference between this new model and what Tesla already exists
Likely based on the Model 3 or Model Y
Will resemble the overall form and shape
Cybercab
Cybercab will use the unboxed manufacturing strategy, and is scheduled for volume production in 2026.
Sample production validation is ongoing now
First builds will happen near the end of Q2
Production is on-schedule at Giga Texas
No new building is being built, it will be built inside already planned space
Unboxed method is progressing well
It is the basis for the Cybercab’s manufacturing process
It lowers the cost of production and increases the level of automation considerably
Tesla is working on marrying large assemblies together, fixing vehicle ceiling connections, and recently completed corrosion testing
Unboxed methodology will eventually be incorporated into other lines
Cybertruck is already benefiting from some aspects of this method
Long term goal is a 5 second cycle time for Cybercab
Giga Shanghai currently has a 33 second cycle team for Model Y
Current Vehicles
Giga Texas produced its 400,00th vehicle in April, and Tesla launched the Cybertruck Long Range (RWD).
Giga Nevada achieved record battery pack production this quarter.
Model 3 and Model Y deliveries in the US (and Canada) are now made with 100% US-built battery packs.
Tesla achieved record orders in a single day in the Asia-Pacific region with the launch of the Refreshed Model Y.
This is the most competitive region for EVs, and a validation of Tesla’s cost structure and positioning.
Giga Berlin built its 500,000th Model Y this quarter.
Tesla has officially opened the first overseas market for the Cybertruck - Saudi Arabia.
Q1 is historically the worst quarter for auto sales, and the best quarter to do production swaps
Tesla used this as an opportunity to do the swap at all 4 factories around the world at the same time
Never been done before - especially as 1.1 million Model Y’s are built per year globally.
Optimus
Tesla’s Fremont factory is preparing production for the Optimus pilot line for 2025, and wider deployments of Optimus for internal Tesla use is expected this year.
There has been good progress on finalizing Optimus so far, still in prototyping stages
Tesla expects its pilot production line to begin running near the end of 2025
Several thousand units should be working in Tesla’s factories by the end of the year
Optimus ramp will be challenging, lots of new and unique components Tesla doesn’t make already
Optimus will use the AI4 computer
Shoulder actuators use permanent/rare earth magnets
Working with China to get a license for use
Goal is 1 million units per year by 2030
Batteries
The 4680 Cell (Cybercell) is IRA-complaint and eligible for the US Federal EV Rebate.
It is the lowest cost-per-kWh cell.
Tesla has diversified and protected the supply chain, and each component for the 4680 is sourced from at least two countries.
Lowest cost cell of any cell available on the market right now
Easy to build a flashy product that does one thing (e.g. charging fast) well, but difficult to scale it up and be profitable
Tesla’s lithium refining and cathode production plans will start production in 2025, moving critical battery production to the US.
Will be the biggest lithium refinery outside of China, and could potentially expand to be the biggest.
Cathode production will also make a big impact
Anode production or removing anodes entirely is being worked on
Tesla is no longer supply constrained for vehicle batteries, but is constrained on LFP batteries for North America due to tariffs.
Supply Chain
Tesla is continuing to localize supply chains where possible
Makes sense from a cost and logistics risk standpoint
Supply chains should be located on the continent of which the vehicle is built
Tesla is the least impacted car company in respect to tariffs
Places Tesla in a stronger position than their competitors
Elon believes in lower tariffs, and advocates for them
Tesla will be impacted by the May tariffs due to part production in Canada and Mexico, no way around this right now
Tesla has to buy equipment from outside the US and import it - it is expensive to bring in equipment from China
China has the most capacity to provide this equipment
Tesla is working to on-shore production of LFP, as most Tesla Energy batteries are supplied from China
There is an outsized tariff impact on Tesla Energy at the current time, and Tesla is looking at non-China suppliers of Lithium
Tesla is continuing to focus on adapting to policy changes
85% of US-built vehicles have North American content
95% of Asia-Pacific vehicles have Asian-Pacific content
Vertical integration and local partnerships are the key to increasing these
Tariff risks are higher for low-volume platforms (S, X, Cybertruck)
Tesla can bridge and cover production for other regions in times of crisis
Tesla is building strategic banks of parts they cannot vertically integrate, such as processors and microelectronics
Tesla is working to reduce or stop the reliance on rare earth magnets as much as possible
Energy
There was a 154% increase in energy storage deployed YoY, for a total of 10.4GWh.
Tesla is experiencing continued rapid growth in the energy market, but deliveries remain volatile due to the nature and scale of the projects.
Megapack expands grid capabilities
Tesla is expecting more demand for Megapack in the near future due to the increasing use of AI.
Megapack itself is extremely useful for many industrial use cases, not just AI.
It can effectively double grid capacity by buffering energy usage during off-peak hours
Tesla has many orders in the GWh range already, and is expecting demand in the TWh range in the future.
Tesla is supply constrained on Megapack
Tesla deployed 1 GWh of Powerwall this quarter.
Extremely positive reception from customers; Tesla is supply constrained.
Tesla delivered 1.4TWh of electricity by Supercharging this quarter, with a 26% YoY growth.
Megafactory Shanghai is now online and producing Megapacks, over 100 are on-site and produced, ready to be shipped (not counted this quarter!)
Tesla expects 20GWh of annual production due to the localized supply chain, and up to 40GWh in the future.
Misc.
Tesla is working on getting into India, cars going in are subject to 70% tariffs and 30% luxury tax
Would be an excellent market, aimed at India’s middle class
No discussion about localizing production in India at this time
Giga Berlin and Giga Shanghai likely have enough capacity
Tesla acknowledged that vandalism, unwarranted hostility, and brand image have suffered in several markets, and likely played an impact, but did not have a functional impact on demand
In Q&A, Tesla’s executive team mentioned:
Biggest impact was reduced Model Y production
Tesla remained a best seller in Q1 in multiple regions, and interest remained high
Tesla experienced the highest number of test drives in this quarter, ever
Tesla isn’t immune to macro economic effects
Elon’s Opening Statement
Elon’s opening statement was interesting - and normally we just integrate it right into the rest of the points, but we’ll break it out here because it is fairly important.
Elon acknowledges blowback for his time at DOGE
He believes that his work there is still important
DOGE team has made a lot of progress
Elon wanted to focus on fighting waste and fraud to benefit the US
Most of the work with DOGE is done
Time with DOGE will drop significantly as of next month
Elon will continue to work with DOGE throughout the current term
1-2 days per week as needed
Elon says he will return to focusing on Tesla
DOGE’s mandate ends in July 2026, so Elon will likely have to step away entirely then unless it is extended
This will be a bumpy year for Tesla
Elon is optimistic about the future of the company, but acknowledges 2025 will be challenging, but he doesn’t go into details
Still believes the future of the company is on large-scale autonomy
Both cars and humanoid robots
If Tesla can execute on autonomy, it is well placed for the future
Financial
Tesla saw a 20% YoY decline in total automotive revenues
Partially due to a 15% decline in gross profit, and 9% rise in operating expenses
Tesla saw non-GAAP earnings per share drop to $0.27, from $0.45 in Q1 2024, and $0.60 in Q4 2024.
Tesla attributed the majority of the decline in its vehicle deliveries due to the ramp of the Model Y across all four of its factories globally. The first time any automaker has launched a new model across all factories at the same time.
Tesla’s average selling price (ASP) also declined due to a mix of sales and financing incentives.
Overall, operating income decreased 66% YoY to $0.4B, which is a 2.1% operating margin.
Tesla saw growth in the energy generation and storage sectors (Tesla Energy), and also a higher regulatory credit revenue for this quarter.
Tesla’s continued ramp of the Cybertruck has seen a lower cost associated with its production as of Q1 2024.
Tesla’s CAPEX for 2025 will be in excess of $10 Billion
Tesla is still evaluating what and where to invest.

Q&A Questions
The questions asked during the Q&A portion of the call come directly from investors. These are currently the top-voted questions, so we’ll likely see answers to several of these questions:
What are the highest risk items on the critical path to robotaxi launch and scaling?
When will FSD unsupervised be available for personal use on personally-owned cars?
Is Tesla still on track for releasing “more affordable models” this year? Or will you be focusing on simplified versions to enhance affordability, similar to the RWD Cybertruck?
Does Tesla see robotaxi as a winner-take-most market, and as you approach the Austin launch, how do you expect to compare against Waymo’s offering, especially regarding pricing, geofencing and regulatory flexibility?
Can you please provide an update on the unboxed method and how that is progressing?
How is Tesla positioning itself to flexibly adapt to global economic risks in the form of tariffs, political biases, etc.?
Does Tesla still have a battery supply constraint (noted on Q4 ER call) and how does this change w/tariffs?
Did Tesla experience any meaningful changes in order inflow rate in Q1 relating to all of the rumors of “brand damage”?
Regarding the Tesla Optimus pilot line, could you confirm if it is currently operational? If so, what is the current production rate of Optimus bots per week? Additionally, how might the recent tariffs impact the scalability of this production line moving forward?
Robotaxi still on track for this year?’
Look Back at 2025 Q1 Numbers
Most of Tesla’s Q1 deliveries, 323,800 units, were unsurprisingly for the Model 3 and Model Y, while the “Other Models” category (including the Cybertruck, Model S, and Model X) accounted for 12,881 deliveries.
Comparing these numbers to Q1 2024, the Model 3/Y is down about 13%, while the Model S/X and Cybertruck are down about 24%.
In terms of production, Tesla built 345,454 Model 3/Y vehicles and 17,161 from its “Other Models” line. The company attributed the production drop to the Model Y changeover but stated that the ramp is “going well.” However, deliveries and production were both down year over year.

Although Tesla doesn’t officially break down its numbers by region, Troy Teslike, who closely monitors Tesla's delivery and production numbers has provided estimates that show Tesla’s deliveries across regions. Tesla delivered the most vehicles in China this past quarter, so it’ll be interesting to see if this trend continues.
His estimates for the regional break down are below:
