A battery electrical characteristic simulation system and simulation method thereof

Abstract

The invention discloses a battery electrical characteristic simulation system and a simulation method thereof. In the solution provided by the invention, the control unit controls S1 so that when the A port of the bidirectional power conversion unit is connected to the DC power supply unit, the DC power supply provides The unit discharges to the B port through the A port of the bidirectional power conversion unit. When the A port of the control bidirectional power conversion unit is connected to the DC load unit, the B port of the bidirectional power conversion unit charges the DC load unit through the A port, and the control unit passes Control S1 to change the direction of energy transfer of the bidirectional power conversion unit, thereby controlling the performance of the external electrical characteristics of the battery electrical characteristic simulation system, realizing the function of simulating the battery, that is, the battery electrical characteristic simulation system provided by the present invention can be used to realize other supporting electronics. The test of equipment saves test time and can meet the needs of various test environments.

Description

technical field [0001] The present invention relates to the technical field of batteries, and more particularly, to a battery electrical characteristic simulation system and a simulation method thereof. Background technique [0002] Batteries are widely used in current industrial fields, such as electric vehicles, power tools, smart wearable devices, etc. However, it is very time-consuming and labor-intensive to use real batteries to test other supporting electronic equipment, and it is usually time to complete a charge-discharge cycle test normally. It takes more than ten hours, and the full life cycle of a battery usually has more than 500 charges and discharges. In addition, it is difficult for a real battery to meet the testing needs of different battery failure states or environmental conditions such as low temperature conditions. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a battery electrical chara...
