New Energy Vehicle Motor Test Cooling and Heating System

First: Introduction of new energy vehicle drive motor test cooling and heat management system:

The liquid energy process test cold and heat management system is mainly used to simulate the reliability test of high temperature or low temperature, mainly for new energy vehicles, in the drive, motor test, battery pack test, so as to simulate the actual working conditions. Testing of environmental adaptability and reliability during transportation and storage of electronic technology products (including power components, materials, motors, etc.), and is widely used in aerospace, power equipment, chip packaging, electronics, rail transit, national defense, Research and other fields

Second: application scenarios:

LNEYA new energy high and low temperature test system is mainly used in the following fields in electric vehicle testing:

Liquid-cooled power battery and its management system: liquid-cooled test for power battery cell/module/system (battery pack), battery management system, and heat sink design and development

Micro motor: sunroof/side window/wiper

Drive motor (MOTOR): single motor/double motor/three motors/four motors/powertrain

Drive Motor Controller (MCU): Passenger Car MCU/Commercial Vehicle MCU

Charging pile: AC charging pile/DC charging pile/charging interface/charging cable

Third: The characteristics of LNEYA new energy vehicle drive motor test cold and heat management system

1. Liquid energy process test The cold and heat management system is a set of cycle tests consisting of refrigeration compressor units, cold storage tanks, temperature control water tanks, circulating pumps, and control devices (flow meters, electric control valves, pressure transmitters, and sensors). system.

2. Liquid energy process test cold and heat management system: Siemens PLC control, Chinese display, touch screen operation interface. It can sense, calculate and adjust various parameters of the system. Conduct multi-stage tests for the cycle, set the output flow according to the requirements, and monitor the output pressure. So as to realize the graph of the unit’s temperature, flow, pressure, cooling rate, time, etc., and the temperature curve.

3. Liquid energy process testing cold and heat management system: a wide range of test variation usually from -40 to 200 ℃. When carrying out the tolerance test, the continuity test can be carried out, and the temperature control accuracy of various modes such as high and low temperature rapid cooling can reach ±0.1℃. The flow accuracy can reach ±0.2L/min, and the temperature conversion rate is 4 ℃/min.

4. The selection and configuration of the constant temperature system for the high and low temperature cold and heat test are determined according to the needs of the user, and the tests of various temperature ranges and accuracy and the application of different processes are carried out.
