What is the best charger in electric car charger? What are its advantages? What are the functions?

Electric car charger is a charging device specially configured for batteries of electric bicycles! Classification of chargers: whether there is a power frequency (50 Hz) transformer or not can be divided into two categories.

Freight three-wheeled chargers generally use chargers with power frequency transformers, which are large in size, heavy in weight and consume a lot of electricity, but reliable and cheap; Electric bicycles and motorcycles use the so-called switching power charger, which saves electricity and has high efficiency, but it is easy to break down.

The correct operation of the switching power charger is: when charging, plug in the battery first, and then add the city power; When the power is sufficient, cut off the power first, and then unplug the battery. If the battery is unplugged before charging, especially when the charging current is large (red light), it is very easy to damage the charger.

Commonly used switching power supply chargers are divided into two categories: half-bridge type and single-excitation type, and single-excitation type is divided into forward type and flyback type. Half-bridge has high cost and good performance, and is often used in negative pulse chargers. Single-excitation type has low cost and high market share.
