If you drive a Tesla, you might ask about some occasions how much you have to charge your battery before the trip. Automatic reflexes are likely to charge up to 100% as much as you can. Why don’t you if the battery fee is 100% maximum and you want to get the longest range from it?
This is not that simple, and you usually can’t charge your tesla battery up to 100%. Technically, you can still charge your battery to the maximum, but Tesla does not recommend it unless you plan a long trip. In fact, with the design that most EV manufacturers don’t even bother telling you how long it takes to charge up to 100%. This is also the same reason that most of the charging fasts slow down after your EV battery is 80% (through National Geographic). Want to know the reason? Just ask Elon Musk.
Regenerative braking will not be effective if you charge up to 100%
When someone on Twitter asked Elon Musk if he could fill Tesla up to 100% every night, he answered “costs up to 90% to 95% and you will be fine.” Musk went further to state the reason, “With 100% charging conditions, regen braking is not functioning, because the battery is full, so the car is not energy efficient.”
To put it in the context, the Tesla vehicle uses regenerative braking to convert kinetic energy into electricity every time you involve the brakes. According to Electrek, regenerative braking can recycle about 30% of the use of Tesla batteries. However, if you charge your tesla up to 100%, the kinetic energy converted into electricity will be wasted because it will not be stored in the battery. Regenerative braking is now a standard feature in all Tesla vehicles produced since 2020, but if your Tesla is made before 2020, you can choose between “low” and “standard” regenerative braking modes.
Filling up to 100% can reduce your tesla battery life
In another tweet, someone asks Elon Musk, “What’s best for long-term batteries … 90%-> 40%cost every day, or 80%-> 30%?” Tesla CEO answered, “80% to 30%.” This confirms the general consensus that charging EV batteries up to 100% can reduce its age. This is because your tesla battery package is made of lithium-ion, like a smartphone battery. From what we know about lithium-ion batteries, they decrease faster if you charge up to 100%-or if they spend zero. So it is not surprising that most EV vehicles actually do not charge up to 100% even if the computer tells you the battery fee is 100% (through Globe and Mail).
According to a study conducted by the University of Michigan, you should also avoid leaving a charger connected to your EV after a 100%battery. This helps prevent the battery from being too hot, which can speed up its degradation. Fortunately, Tesla’s onboard computer is designed to automatically prevent the battery from excessive charging.
