The car charging pile is an outdoor charging system for electric vehicles and electric vehicles. It is generally set up in public buildings, residential parking lots, and public parking lots. The charging pile can be set with different voltage levels, so as to charge different types of electric vehicles and electric vehicles, which is convenient to use. The charging pile resistance load cabinet is used for the detection and maintenance of the charging pile. The following will introduce its classification, test functions and performance characteristics:
1. Classification: According to the access load voltage, it is divided into three types: three-phase, single-phase, and three-phase four-wire system.
2. Test function: The charging pile load cabinet can be used to test various types of charging piles, detect the actual output power of the charging piles, and can also be used for factory inspection, engineering acceptance, electrical testing and daily maintenance of car charging equipment. .
3. Performance characteristics: The load cabinet adopts three-phase independent control of the load, the load power is adjustable, and the adjustment accuracy is accurate to 1W. The charging pile test product can also be connected to the PC for data transmission, and also has the function of report printing, which is easy to use.
There are DC charging piles and AC charging piles, but at present, the three-phase four-wire AC charging piles are mainly used, so the charging piles are mainly connected to the load with three-phase four-wire system. The charging pile test equipment can be used for For the factory inspection, daily inspection and maintenance of the charging pile, the test is very accurate and the use is very convenient.
