The invention relates to an intelligent battery management system (BMS), in particular to an intelligent battery management system (BMS) suitable for a new energy vehicle. The BMS realizes the judgment on the validity of a power-on signal of the system and the current state of the system through the cooperative work of a signal validity judgment module and a state validity judgment module. Power-on is carried out based on an effective system power-on signal and a stable system state, the workload of a VCU core electronic control unit is liberated, and the situation that power-on of a BMS is delayed is avoided; and a lithium battery is effectively monitored by setting a reasonable monitoring mode, and the service life of the BMS is further prolonged on the premise that the lithium battery is effectively monitored. According to the technical scheme provided by the invention, the defects that a BMS in the prior art is delayed to power on and a reasonable monitoring mode cannot be set for the lithium battery can be effectively overcome.

    本发明涉及电池管理控制系统,具体涉及一种适用于新能源车的BMS智能电池管理控制系统,通过信号有效性判断模块、状态有效性判断模块配合工作,实现了对系统上电信号的有效性以及系统当前所处状态的判断,基于有效的系统上电信号和稳定的系统所处状态进行上电,解放了VCU核心电子控制单元的工作负担,避免出现BMS电池管理系统延迟上电的情况;通过设置合理的监控模式对锂电池进行有效监控,在对锂电池进行有效监控的前提下,进一步延长了BMS电池管理系统的使用寿命;本发明提供的技术方案能够有效克服现有技术所存在的BMS电池管理系统延迟上电、不能针对锂电池设置合理监控模式的缺陷。
