Does Rapid Charging Damage Ev Battery. But there is actually no empirical evidence to support the need for keeping to a maximum of 80 per cent for EV charging. Electric cars use lithium-ion batteries and will deplete over time but they wont be damaged when continuously charged at high power.

But there is actually no empirical evidence to support the need for keeping to a maximum of 80 per cent for EV charging. Battery degradation is less crucial in a phone as most people replace theirs every two or three years. Answered by Keith Moody.
Their test involved 4 Nissan Leaf EVs two of which were charged twice daily on Level 2 chargers and 2 that were charged on Level 3 fast DC chargers.
And our fast chargers have power levels from 50 kW all the way to 350 kW. Charge currents and the resultant cycle life when subjected to fast charging is affected by the battery chemistry. To help protect the battery the charging speed is reduced as the battery gets closer to full charge. Fast-charging of electric batteries can ruin their capacity after just 25 charges researchers have said after they ran experiments on batteries used in some popular electric cars.
