Which electric vehicles use lithium iron phosphate batteries
Manufacturers list battery capacity as either gross (total) or net (usable). Why the difference? To maintain lithium-ion batteries in good condition, they should not be allowed to be completely empty (0% charge) or full (100% charge). The gross capacity is not a particularly insightful spec, so it's best to measure usable. If you are looking to maintain maximum value, the following is the best practice: 1. Keep charge between 20% and 80%. 2. Only charge to 100% when making a long trip, preferably just before. Almost all EV batteries are lithium-ion, and different lithium-ion chemistries are named after their elements. Each chemistry has pros and cons – some are. It's a valid question. 1.
