  • Which electric vehicles use lithium iron phosphate batteries

    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.
