Practical aspects of off-grid EV charging

Charged EVs

The most common choices of battery type are lithium iron phosphate (aka LFP or LiFePO 4 ), all of the other lithium-ion chemistries (including recycled batteries from junked EVs), and, finally, lead-acid. The last option is venerable old lead-acid, though perhaps it’s best to relegate it to the proverbial dustbin of history.

For reference, a typical lead acid battery can survive 500-800 cycles while 2,800 cycles is almost 8 years of use assuming one cycle a day. They are usually delivery vehicles working within a neighborhood, and are on the road for 6-8 hour a day and are recharged overnight. The USCAR/DOE long term goal is 5,000 cycles.
