The key problem is that the indicator light can turn green after charging. In the initial stage of charging, large current is usually used for charging, and trickle charging is usually used in the second half of charging, but small current can also fully charge the battery.
The deeper and shallower the battery discharge, the more cycles. Therefore, frequent charging is beneficial to the cycle life, and it is best to choose a charger with high reliability and precision.
Introduction of electric vehicles:
Electric vehicles, that is, electric drive vehicles, also known as electric drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, an electric vehicle is a vehicle that uses batteries as energy source and converts electric energy into mechanical energy through controllers, motors and other components to control current and change speed.
The first electric car was made in 188 1. The inventor was Gustav Truff, a French engineer. This is a tricycle driven by lead-acid battery and DC engine.
