How many new energy testing equipment are there?

New energy generally refers to renewable energy developed and utilized on the basis of new technologies. The new energy sources that can form industries in China mainly include hydropower, wind energy, biomass energy, solar energy and geothermal energy. It is a kind of clean energy that can be recycled, and the new energy detection we are talking about here refers to the detection of new energy vehicles.

Generally, the components for testing new energy vehicles include CO2 air conditioning pipe, nylon bellows, cold water plate, motor, water pump, water valve, controller shell, electric stack, hydrogen bottle, high-pressure pipeline, check valve, etc. What kind of test machines and equipment will be used to test the safety of these components?

The cooling system test-bed for parts and assemblies is used to test the cooling performance according to the battery system, motor operation and control assembly in electric vehicles, to monitor the whole system in real time, to simulate the operating conditions of the on-board cooling system, and to analyze and evaluate the overall performance and control strategy through the communication between the on-board air conditioner, controller and ECU. It can communicate and test directly with the whole vehicle, and the test ports are complete, including pressure, temperature, flow, cooling power, pipeline pressure loss, pump head and flow curve, etc.

The test object is to test the heat dissipation performance according to the battery system and motor operation control assembly in the electric vehicle, simulate the operation condition of the on-board heat dissipation system, and analyze and evaluate the overall performance and control strategy of the on-board air conditioner, controller and ECU. The test contents include high and low temperature, pressure cycle, flow control, water pump test, controller test and heat source load simulation.

Gravel impact tester, which is suitable for adhesion failure test of external coating, adhesion failure test of different layers in coating system, brittle thickness of hard glass material, coating film thickness with excellent anti-peeling, anti-collision, anti-wear test of plastic and glass and other related tests.

The high and low temperature cooling cycle comprehensive test-bed includes battery pack, vehicle motor, hydrogen fuel cell membrane and electrode, new energy vehicle cooling system, controller, water pump, etc. The test contents include high and low temperature, pressure cycle, flow control, water pump test, controller test, heat source load simulation and flow resistance test.

The pump durability test bench and biaxial fatigue test device are mainly used to evaluate the fatigue characteristics of pipelines under high temperature and long-term load conditions. The external diameter of the pipeline is changed by alternating peak-valley pressure inside the pipeline, so as to test the strength of the pipeline and other required performance parameters and realize the fatigue strength experiment of the pipeline.

The test object is the water pump system in electric vehicle. Simulate the whole system, monitor it in real time, simulate the actual operating condition of the pump, and analyze and evaluate the pump. The test contents include high and low temperature, pressure cycle, flow control, water pump test, voltage test, pressure difference test and life durability test.

Lithium battery precision pressure control unit, the pneumatic pump pressurizes the low-pressure test medium under the action of high-pressure air, and the pressure of the generated high-pressure medium is determined by the pressure of the air input to the pneumatic pump. High-pressure medium enters the specimen all the way and the mechanical pressure gauge at the same time. At the end of the test, manually open the unloading valve to release the system pressure.

The air conditioning system test bench is mainly used for various types of pressure pulse tests, such as automobile steering pipes, brake pipes, air conditioning pipes, fuel pipes, cooling water pipes, radiator pipes, warm air pipes, air cleaner hoses, turbocharger pipes, engineering hydraulic pipes, aviation pipes, hard pipes or joints, heat exchangers, air conditioners, filters, etc. , widely used in factories, product quality inspection, scientific research institutions and other production inspection, development and research fields.

The pipeline fatigue test-bed adopts modular design, which is independent of each other and does not affect each other, and is convenient for on-site scheduling and after-sales maintenance service as a whole; The independent and automatic exhaust system can effectively remove the gas in the circulating pipeline, thus ensuring the stable and unbiased output of the test pressure; With test interrupt protection function; The test must be interrupted for some reason, and the current test can be continued when the test is repeated; Save the relevant setting parameters of the test. When testing the same specimen and the same standard, the test parameters can be directly extracted without setting. Safety measures: it has the functions of liquid level alarm, leakage alarm, abnormal alarm, overload protection, emergency pressure relief and safe shutdown; Remote assistance software is installed on the equipment control computer. When the equipment fails, the maintenance personnel can remotely control and enter the interface of the equipment computer. Through the combination of field analysis and control, the purpose of analyzing and solving the fault is achieved.
