Highly-efficient management system of automobile storage battery

Abstract

Provided is a highly-efficient management system of an automobile storage battery, pertaining to the technical field of management systems. The invention particularly relates to the highly-efficient management system of the automobile storage battery. The invention provides the highly-efficient management system of the automobile storage battery which can prolong service lifetime of a battery integration system. The system comprises a main system module, a man-machine interface module, a circuit detection bus, a battery pack detection module, a protection center control unit and a storage battery detection concentrator. The storage battery detection concentrator is connected with an internal circuit of a battery pack module. The number of links of the battery pack module is confirmed by standard rated power of a motor of an electric car and capacities of storage batteries. The main system module comprises a micro-controller, a protection and safety assessment module connected with an MCU, an active equalization module connected with the MCU and a heat management module connected with the MCU.

Description

technical field [0001] The invention belongs to the technical field of management systems, in particular to an efficient management system for automobile storage batteries. Background technique [0002] As a new energy vehicle, electric vehicles require large motor power, strong power, fast speed, and long running time. This requires several or even dozens of battery packs to be arranged in series and parallel to increase the energy and storage capacity of the battery. At present, the motor and electronic control technology are relatively mature, and there is still a bottleneck in the battery assembly technology. The prominent problem is that the number of charge-discharge cycles when the capacity of the battery system decays to 80% of the initial capacity is much lower than the initial capacity of a single battery cell decaying to 80%. The number of iterations for the value. Contents of the invention [0003] The present invention aims at the above problems and provides ...

At present, the motor and electronic control technology are relatively mature, and the battery assembly technology still has a bottleneck. The outstanding problem is that the number of charge-discharge cycles when the capacity of the battery system decays to 80% of the initial capacity is much lower than the initial capacity of a single battery cell decaying to 80%. The number of times to loop through the value
