This invention provides a battery management system (BMS) overcurrent protection method based on a finite element model, belonging to the field of new energy battery technology. The method includes: power-on initialization; acquiring real-time current sampling values ​​of the battery module, or simultaneously acquiring ambient temperature; calculating the simulated temperature of the battery module based on a pre-constructed finite element thermal model; comparing whether the simulated temperature exceeds a preset protection threshold, and if so, triggering overcurrent protection. The finite element thermal model is used to simulate the heat accumulation process of the battery under current, with the simulated temperature continuously increasing with increasing current, and the overcurrent protection delay time continuously decreasing with increasing current. This invention simulates the actual temperature rise of the battery using a finite element model, achieving a smooth and continuous change in the overcurrent protection delay time with current, solving the problem of mismatch between traditional stepped protection and battery thermal characteristics, and improving the safety and reliability of the battery system.
