Product Name: power battery analog power supply



In the development and production of electric vehicles, inverter, motor and other systems with power battery as the power supply must be strictly tested. In the development and testing of electric vehicles, power batteries are needed.



There are some defects in the application of power battery in automobile test, such as low efficiency, high cost and long test period. At present, most domestic automobile companies use regulated power supply to develop and test automobiles. But application



It is difficult to meet the requirements of automobile test by replacing battery with regulated power supply. In order to solve this problem, Shaanxi blue sea Electric Co., Ltd. launched the electric vehicle power battery simulation power supply, which can accurately simulate the power battery's



The internal resistance and output characteristics can replace the power battery for electric vehicle test, reduce the test cost and improve the test efficiency.

1. It can simulate the output characteristics of the power battery when the electric vehicle accelerates;



2. With energy feedback function;



3. High output precision, with remote feedback function of voltage compensation, to ensure the voltage stabilization precision of the tested terminal;



4. Simulate the internal resistance of the power battery. The internal resistance value can be set to simulate different types of batteries in different states (such as electricity) so that the output of voltage and current is consistent with the actual output of the power battery;



5. The battery characteristic curve can be programmed to simulate the battery.
