The only way to check tesla battery degradation is to discharge it completely. So, it will provide the data on the EV screen to evaluate the problem. Normal driving does not provide an accurate picture because it only uses a portion of the battery’s capacity.
Various apps, such as TeslaFi, record your vehicle’s statistical data, including charging capacity, providing a more accurate picture of your battery’s health based on the data accumulated over time.
The battery in your vehicle is not similar to the battery in your phone. All-electric vehicle batteries gradually lose their ability to store energy over time, so do not anticipate your used vehicle having the same charging capacity as a new one.
Every 10,000 miles, a tesla is expected to lose 2.9% of its charging capacity.
Here are some additional tips for improving your driving efficiency and preventing degradation.
- Maintain the tyre pressure on your car.
- The drivers-side door jamb contains a list of recommended inflation pressures.
- Reduce the number of unnecessary goods you are carrying because a vehicle needs more energy to move when it is heavier.
- When not in use, take off the back or roof racks.
Tesla Battery Degradation Chart
One of the main concerns of new electric car owners is degradation, which indicates the loss of capability over time as mileage increases.
The more a rechargeable battery can operate, the further it can keep the vehicle running and avoid being scrapped for recycling.
Each point on this chart shows a Model S or Model X in the EVs client sheet at the end of 2017. The “Y” axis indicates the car’s current cell capacity as determined by EVs exclusive management system.
In contrast, the “X” axis shows the entire usage of the battery’s capacity since the car was new. It demonstrates that the 90-kWh initial usable capacity is 85 kWh.
After 20,000 kWh or 235 cycles, corresponding to more than 60,000 miles, the car’s batteries lose an average of roughly 6 kWh.
The 85-kWh cell pack starts with a useful capacity of approximately 80.5 kWh and decreases to approximately 77 kWh after 20,000 kWh on average.
The 90-kWh cell pack degrades nearly twice as quickly as the earlier 85-kWh cell pack during the first few years of Service.
There are three essential guidelines to keep your car batteries in good condition.
- Don’t always fully charge the vehicle.
- Never regularly allow the status of charge to fall below 10%.
- Keep the batteries from getting too hot.
- Using the Supercharger stations frequently falls under this category.
- The batteries warm up more quickly with rapid charging.
How to Check Tesla Battery Degradation
Owners can now undertake this check themselves via the EV mobile app. To determine whether your vehicle’s range is within its limits or not, the range in miles is displayed on the app’s top.
In addition, a charge graph is displayed. While the battery’s level is not expressed in percentages, it is simple to assess.
Then, access your mobile app and select Service, followed by ‘Request Service.’ When prompted to describe the problem, tap ‘Battery,’ then ‘Range,’ and input’ lack of range’. Tap ‘Next,’ and the app will do a self-diagnosis to determine the battery’s health.
The app will display ‘No issue found if your range and battery are normal.’ The app will then explain briefly how your unique driving patterns might influence your vehicle’s range, and why fluctuations in your displays are typical and anticipated.
The majority of EV batteries and other services provided by electric vehicle companies have either a big battery capability that can hold a load for a long time or a low capacity which can charge quickly. But an excellent thing is that a Tesla allows customers to own both!
One of the most common concerns of potential EV buyers while shopping for a new vehicle is degradation. With a Tesla, you don’t have to worry about that.
The power in any Tesla vehicle will last at least 267 miles on a single charge and can last up to 35 years. The battery’s health is determined by how you drive.
Currently, EV provides approximately 375 miles of range per full charge. The car’s mileage is also affected by the battery’s size.
The Model 3 Standard, on the other hand, does have the cheapest capacity and costs about $40,690, making it the least expensive choice. The cost of the Base Model Long Range is roughly $84,490.
The battery’s health will likely deteriorate with usage. Check how many miles your vehicle has been driven and subtract 3% from its capacity for 10,000 miles on the odometer. Maintaining mileage in cars necessitates extensive maintenance that is not required with electric vehicles.
Driving safely, keeping the tyres inflated, braking softly, and reducing excess weight inside the car reduces the chances of encountering range concerns. And, as with any automobile, how you maintain and care for your car will help it, and its batteries will survive longer.
Scan Tesla Battery Degradation
Firstly a unique wiring harness is required. It is because the data we want to access is only available on the CAN bus, which is the internal bus of the car where automotive components communicate with one another.
The OBD2 ports in the Model S, 3, X, and Y only provide +12v and the vehicle’s VIN. The Bluetooth in the automobile is only for voice (speaker phone) and music.
Your car has most likely recently received a firmware upgrade; Tesla has changed how that signal is interpreted, and the app has not yet been updated to decode it properly. Tesla is continually working on these issues to provide fully functional apps.
A major concern among Tesla owners is calculating degeneration or determining the battery’s health, which is not an easy task. Charging protocol is critical if you own an electric vehicle.
Calibration issues with EV batteries might occur due to poor charging habits. As a result of these calibration errors, degeneration may appear – even in a relatively new car.
The high cost of batteries is one of the key concerns about whether electric cars can replace traditional automobiles. A longer overall lifespan reduces the need to replace the motor, but a less expensive pack reduces both the initial price and the replacement cost.
