If you wish to hold your EV’s battery alive and kicking for lots of of 1000’s of miles, there are just a few suggestions and methods to creating that occur. Identical to your gas-powered automotive, you possibly can’t flagrantly ignore the foundations of longevity. Storing your EV at one hundred pc cost for a prolonged time period in the midst of the new summer time is the electrical equal of getting in your gasoline guzzler on a chilly winter morning and flooring the throttle to heat it up. Give your automotive’s battery pack a little bit kindness, and it ought to pay you again by staying sturdy for years to come back. Based on Engineering Defined, our fellow mega nerd Jason Fenske, these are the three guidelines it is best to comply with.
Rule Quantity One: Don’t retailer your EV at one hundred pc state of cost, and particularly don’t do that if the climate goes to be scorching. Lithium-ion batteries will lose capability and degrade over time, that’s only a reality of life. However that capability loss will increase dramatically if you happen to’re storing the battery absolutely charged for prolonged durations of time, and even worse because the mercury within the thermometer rises. Earlier than you exit of city, be certain that to run your EV all the way down to 30 p.c or much less; it’s simply higher for it. Like a can of Stabil in your gasoline tank, I assume.
Rule Quantity Two: Don’t run your battery all the best way out earlier than recharging it, if you happen to may also help it. “A bunch of small prices is a lot better [for the health of your battery] than rare full-depth prices,” says Fenske. Retaining your battery in the identical 20-percent SOC vary on daily basis is a lot better for the automotive than ready to cost from zero to 100 on the finish of the week. Attempt to hold your battery from dipping beneath 25 p.c, if you happen to can. Clearly this isn’t at all times sensible, however it’s a very good apply if you happen to can handle it.
Rule Quantity Three: Don’t routinely cost all the best way to one hundred pc. For street journeys or prolonged journey days the place you want the additional cost, topping up your electrons can’t actually be prevented. However for each day use, it’s greatest to maintain your battery’s higher restrict beneath 80 p.c to make it final so long as doable. That final little bit of charging after the battery hits its plateau is creating gasoline formation inside your battery, which degrades the battery over time.
In the event you do this stuff, you’ll have a contented and wholesome battery for a lot of, a few years to come back. Glad driving!
