UCR researchers find commercial fast-charging damages EV batteries, propose new internal-resistance-based technique

Green Car Congress

At 80% capacity, rechargeable lithium-ion batteries have reached the end of their use life for most purposes. Capacity loss, internal chemical and mechanical damage, and the high heat for each battery are major safety concerns, especially considering there are 7,104 lithium-ion batteries in a Tesla Model S and 4,416 in a Tesla Model 3.
