Battery electrical characteristic simulation system and simulation method thereof

Abstract

The invention discloses a battery electrical characteristic simulation system and a simulation method thereof. According to the scheme provided by the invention, when a control unit controls a port Aof a bidirectional power conversion unit to be connected with a DC power supply unit by controlling an S1, the DC power supply unit discharges to a port B through the port A of the bidirectional powerconversion unit; when the A port of the bidirectional power conversion unit is controlled to be connected with a DC load unit; the B port of the bidirectional power conversion unit charges the DC load unit through the A port. The control unit changes the energy transmission direction of the bidirectional power conversion unit by controlling S1. Therefore, the performance of the battery electricalcharacteristic simulation system on the external electrical characteristics is controlled, the function of simulating the battery is realized, the battery electrical characteristic simulation systemprovided by the invention can also be used for realizing the test of other matched electronic equipment, the test time is saved, and the requirements of various test environments can be met.

Description

technical field [0001] The invention relates to the field of battery technology, and more specifically, to a battery electrical characteristic simulation system and a simulation method thereof. Background technique [0002] Batteries are widely used in the current industrial field, such as electric vehicles, electric tools, smart wearable devices, etc. However, it is very time-consuming and labor-intensive to use real batteries to test other supporting electronic devices. It is usually necessary 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 charge and discharge times. In addition, it is difficult for a real battery to meet the test needs of different failure states of the battery or environmental conditions such as low temperature conditions. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a battery electrical ...
