If you have enough time, give priority to slow charging, that is, standard current charging, which is the best for the battery. Fast charging is more harmful to the battery, and there is no big problem with occasional use. If the battery is often quickly charged, the service life of the battery will be significantly shortened. Note: 12 amps flush for about 10 hours, 20 amps and 28 AMps 30 AMps need 12 hours, usually, rush to the green light and float for three hours. Try not to exceed 12 hours, and do not rush when there is about 80% of the power, and keep the remaining 20% or so each time. Every two or three months, it is a deep discharge, so that your electric car battery will live longer.
Using slow charge mode is the most suitable way to charge your car
