The application provides a
battery system construction method, device,
electronic equipment and readable storage medium. Performance requirements of a target
battery pack are obtained, risk reasoning is performed based on a battery
safety knowledge graph, a
safety margin coefficient is obtained, missing structure parameters are completed, and completed structure parameters are obtained. Based on the
safety margin coefficient, the swelling amount of the
battery cell under a preset working condition is predicted, and the safety gap of the
battery cell arrangement is determined. Based on the target
voltage value, the target energy value and the hardware discrete constraint of the battery
management system, a topology search is performed, and a series-parallel topology combination is obtained. The arrangement mode of the
power distribution unit is used as a decision variable for multi-objective optimization, and a collaborative arrangement scheme of the electrical and mechanical spaces is obtained. Based on the completed structure parameters, the safety gap, the series-parallel topology combination and the collaborative arrangement scheme, the
battery system is constructed. In this way, the multi-
physical field constraint and the multi-objective collaborative optimization are fused under the performance requirements for automatic construction, and the construction efficiency of the
battery system is improved.
