Single-cell high-boost battery for low-speed electric vehicle and working method of single-cell high-boost battery

Abstract

The invention relates to the technical field of batteries, in particular to a single-cell high-boost battery for a low-speed electric vehicle and a working method.The battery comprises 1-4 strings of cells, a heat dissipation plate, a boost module and a battery management system; the 1-4 strings of battery cells are connected in parallel, the battery cells are arranged in the battery shell, the upper parts of the battery cells are electrically connected with the boosting module, a heat dissipation plate is arranged at the top of the battery shell, and the battery management system is electrically connected with the boosting module. The battery management system comprises a parameter acquisition module, a feature tracking module, a frequency conversion modulation module, an impedance spectrum mapping module and a self-adaptive current limiting module. According to the battery management system provided by the invention, deep over-discharge or overheating of the aged battery cell due to bearing of overlarge current can be avoided, and the service life of the battery system is remarkably prolonged on the premise of ensuring the boost output stability.
