What is the best type of battery for a BEV?
Large format high power long life deep cycle LiFePO4 is becoming more common, with fast charging nanotechnology versions being sought after next. Flooded lead acid golf car batteries are the most popular for conversions, but weigh several times more for the same capacity at high BEV discharge currents due to the Peukert effect, and have hydrogen safety and lead toxicity issues. High power AGMs are also commonly used but require module monitoring and balancing. Gel batteries are sometimes used but do not offer as much power per pound. Starter, backup and low cost wheelchair batteries won’t last long in BEVs. 45. What is the best type of motor for a BEV? AC induction is most common in OEM vehicles. Series wound DC is most common in conversions. 46. What is the best type of charger for a BEV? One that is high power >= 3 kW but also isolated, power factor corrected, UL and FCC compliant. 47. How do you determine the state of charge of the batteries? The voltage, temperature and cumulative
