At present, the emission of automobile exhaust is still an important factor of the problem of environmental pollution, and in order to treat the automobile exhaust, people develop natural gas automobiles, hydrogen fuel automobiles, solar energy automobiles and electric automobiles to replace fuel oil type automobiles. And among them, the most promising is the electric vehicle. The current electric automobile mainly comprises a direct charging type and a quick-change type. Due to the limitation of charging time and places, many new energy electric vehicles gradually adopt a mode of rapidly replacing batteries for energy supply.

Electric automobile is when changing the battery, trades electric equipment and takes off insufficient voltage battery from electric automobile and forwards insufficient voltage battery to battery transfer equipment, and battery transfer equipment later forwards insufficient voltage battery to the battery compartment and charges. And then, the battery transfer equipment takes out the fully charged battery from the battery bin and transfers the fully charged battery to the battery replacing equipment, and the fully charged battery is installed in the electric automobile by the battery replacing equipment. Among them, for charging of the insufficient-power battery, a battery-end electrical connector electrically connecting the charger to the insufficient-power battery is required.
