The application demand for new energy vehicle motors in passenger cars, commercial vehicles, logistics vehicles, and heavy-duty truck series in the automotive industry is becoming increasingly widespread. The performance and quality of the motor must be ensured during product development and factory testing. Therefore, strict testing of the motor's performance is particularly important.Motor test system is a high-performance test platform that specifically provides performance testing for the motor by providing the external environment of the motor: power supply, load, thermostat, water cooling system, etc.

The new energy vehicle motor testing system adopts a modular and integrated design, and the operating part conforms to ergonomic design, which can complete manual/automatic mode control. It consists of three parts: mechanical system, simulation guarantee system, electrical system, and upper computer software system.

l  Mechanical system: composed of cast iron platform, loading equipment, quick clamping system, shaft connection parts, and other equipment.

l  Simulation support system: composed of environmental warehouses, temperature control systems, and other equipment.

l  Electrical system: composed of bidirectional drive DC power supply, loading control, real-time data acquisition system for sensors (torque, speed, current, voltage, vibration, temperature), data acquisition, current sensor acquisition, electrical parameter measurement equipment, alarm system, and other equipment.

l  Software system: The upper computer testing software is divided into data acquisition communication module, data acquisition setting module, real-time data exchange control module, and data processing module according to the system. The upper computer completes functions such as experimental control, data analysis and display, data recording and export based on the experimental project.

MC series EV test temperature control system provided by Beijing WIIP Co. Ltd. provides constant temperature, constant pressure, and constant current circulating fluid to the motor under test, and performs temperature simulation of the motor under different working conditions.

When selecting a temperature control system, according to the minimum temperature of the battery pack and battery module .

Simulate -40℃ working condition, choose Mca series;

Simulate -20℃ working condition, select Mct series ;

Simulate 5℃ working conditions and choose Mcc series.

MC  series have multiple options,  the flow, pressure, and temperature can be controlled separately; with more functions of air blowing and leak detection.

EV test temperature control system is suitable for different applications and functions to meet all the needs of industry. It has characteristics of wide temperature range, wide flow range, high control accuracy, strong reliability, high field compatibility, complete user interface, mature and stable software, and high service efficiency.

MCc direct cooling EV test temperature control system adopts the direct heat exchange mode between refrigerant and circulating liquid, with high heat exchange efficiency, fast temperature response and high performance.

MCt pressure EV test temperature control system adopts a closed pressurized coolant circulation design. Through system pressurization, the saturated vapor pressure of the circulating liquid (antifreeze) is increased, so as to realize high temperature operation condition of antifreeze; the closed coolant circulation system can isolates the contact between circulating fluid and air, and can keep the circulating fluid from deteriorating for a long time under high and low temperature conditions. It is a favorable assistant for high and low temperature experiments and airtight experiments in EV testing.

MCa cool storage EV test temperature control system adopts a two-stage low-temperature special compressor to realize ultra-low temperature and high temperature control, each output circuit is independent, which can realize independent temperature control of each circuit.
