An EV charging pile load bank is a specialized device used for testing and validating the performance of electric vehicle (EV) charging stations. Mainly used in online debugging, offline detection, aging test, functional verification, etc. of DC charging pile products.
Really simulate the charging process and various faults to avoid the inconvenience of using the actual electric vehicle as the testing device, incomplete test content, inability to simulate real faults, inability to verify the auxiliary power system, and time-consuming charging and discharging of the vehicle power battery Energy consumption and frequent charging and discharging lead to problems such as shortened battery life. At the same time, it can avoid damage to the test vehicle caused by charging pile failure.
Through information exchange between the internal BMS simulator and the electric vehicle DC charging pile, real-time simulation of the battery charging process is realized. When the DC charger charging gun is connected to the test equipment interface, the test equipment is completed according to the national standard of the non-vehicle charger and BMS communication protocol. Connection detection, charging handshake, configuration and charging, detection of charging voltage and current, auxiliary power supply voltage.
The detection process is set up and monitored through the device's built-in touch screen, charging status and fault information are monitored in real time, various types of BMS faults are simulated, and the charger's response to BMS faults is tested.
There is a resistive load inside this test system, and the corresponding load power can be switched according to actual needs. In addition, it can simulate real ground faults and realize online testing of the DC charging pile side edge detection function.
CAN test: physical connection, charging voltage monitoring, charging current monitoring, auxiliary power supply voltage monitoring, fault response, charging status, communication status, automatic charging response and other items
Here's a breakdown of its functions:
• Field Detection Device: It's primarily used for the field installation, debugging, and functional verification of EV charging piles
• AC and DC Charging Pile Testing: The load bank can be used for both AC and DC charging pile tests
• Simulation of Electrical Load: It simulates the electrical load that a charging pile will experience during the actual charging process
• Capacity Testing: It's also utilized to conduct capacity testing on charging piles to ensure they can handle the expected load
• Charging Pile Protocol Communication Test: EV DC Load bank acts as the battery bank simulator, protocol matching test to activate the charging pile charge capability output different voltage and current base on different charging status
In essence, the load bank ensures the safety and reliability of charging piles, which is crucial for the safety of EV users. It allows manufacturers, power departments, and testing units to assess and adjust the charging equipment before it is used in real-world scenarios.
