Can 48v electric car battery starve to death and fast charge be activated?

Yes, but a large current can kill a living battery, ha ha... High current charging itself is harmful to the battery. It only works with constant voltage and current charging.

Some customers are not at home, put the electric car battery on the car, do not turn off the air switch, and do not ride for several months. When I returned a few months later, I found that the car was out of power and couldn't be charged. The charger is plugged in, but it has always been green, even if it is plugged in for 24 hours, it is still green, because the battery voltage is too low, and the charger output voltage difference is too large, the charger can not rush electricity into the battery.

This situation is what everyone usually calls the battery being \"starved\". The voltage of this battery block battery is generally only about 5.6V, and will not exceed 6V. For such batteries, most are replaced. But change a set of batteries hundreds, so it is a pity to change, especially just after the warranty of the battery.
