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.

What is the RLC AC load bank?

Posted on by junxy

An RLC load bank is a device that combines resistive (R), inductive (L), and capacitive (C) loads to simulate real-world electrical loads on power systems during testing. It’s used to validate the condition and output of power systems such as UPS (uninterrupted power supply), generators, transformers, inverters, and PV systems. Here are some key points about RLC load banks:

• Simulation of Various Loads: It can mimic motor loads, electromagnetic devices, and purely resistive loads within a power system

• Testing Power Systems: It helps in highlighting potential hidden faults of power systems before they can cause a power disruption

• Setting Specific Power Factors: RLC load banks offer the ability to set a specific power factor, which is essential for testing backup generators and turbines rated at certain power factors

• Inverter Anti-Islanding Tests: They are commonly used for inverter anti-islanding preventative test experiments, which meet the PV & grid inverter testing requirements for islanding prevention detection, work efficiency test, overload protection test, over-current protection test, power factor test, grid current harmonic test, resonance point test, and more

• Customization: They can be customized for different applications and load voltages as per the need

Overall, RLC load banks are crucial for ensuring the reliability and safety of power systems before they are put into active service. They provide a controlled environment to test and validate the performance of these systems under various load conditions.
