Abstract

The invention relates to a battery management system special for an electric coach. The battery management system comprises a central control module, a CAN bus, a vehicle controller, a battery box, a charger, a vehicle-mounted instrument, an integrated charging and discharging intelligent monitoring module and a heat dissipation device. The battery management system is characterized in that the central control module is connected with the vehicle controller, the charger, the vehicle-mounted instrument and the integrated charging and discharging intelligent monitoring module through the CAN bus; a communication interface is arranged in the central control module to be connected with external equipment; the communication interface is arranged in the central control module for being connected with the external equipment; the charger and the integrated charging and discharging intelligent monitoring module are connected with a power battery box group. According to the battery management system disclosed by the invention, the battery status can be monitored in a real-time manner; and through detecting the external characteristic parameters of the battery, including voltage, electric current, temperature and the like, and adopting an appropriate algorithm, practical training of the estimating and the monitoring of the internal state of the battery is the base and key for effectively operating the battery management system.

Description

technical field [0001] The invention relates to an electric vehicle battery management system, in particular to a special battery management system for an electric bus. Background technique [0002] In electric buses, the power battery accounts for more than one-third of the cost of the whole vehicle, and because electric buses carry a large number of passengers, the reliability and safety requirements of the battery management system are higher than those of ordinary electric vehicles. The battery management system of an electric bus must not only fully consider the susceptibility to electromagnetic interference, the scattered layout of battery modules, and the susceptibility to interference of battery management system communication. The electric bus battery box is composed of several battery modules. The battery modules can be replaced individually to meet the special requirements of charging and discharging. The application of batteries and vehicles must consider various...
