The invention provides a whole electric vehicle battery management system and method, and a pure electric vehicle. The whole vehicle battery management system comprises a whole vehicle low-voltage circuit and a low-voltage circuit acquisition unit. The low-voltage circuit acquisition unit comprises a current acquisition unit, a voltage acquisition unit, a controller and an instrument display unit;the current acquisition unit, the voltage acquisition unit and the instrument display unit are electrically connected with the controller; the current acquisition unit is used for acquiring a currentof a storage battery in a low-voltage circuit of the whole vehicle and transmitting the current to the controller; the voltage acquisition unit is used for acquiring the voltage of a storage batteryin the low-voltage circuit of the whole vehicle and transmitting the voltage to the controller; and when the voltage is lower than a preset voltage value or the current is larger than a preset staticcurrent value, the controller makes the instrument display unit give an alarm. By adopting the technical scheme, the whole vehicle low-voltage circuit condition in the electric vehicle can be detectedin real time so that a user is prompted to maintain or repair in time, and an use experience and a service life of the electric vehicle are improved and prolonged.
本发明提供一种电动汽车整车电池管理系统、方法及纯电动车;整车电池管理系统包括整车低压电路和低压电路采集单元;低压电路采集单元包括电流采集单元、电压采集单元、控制器以及仪表显示单元;电流采集单元、电压采集单元以及仪表显示单元分别与控制器电连接;电流采集单元用于采集整车低压电路中蓄电池的电流,并传输至控制器;电压采集单元用于采集整车低压电路中蓄电池的电压,并传输至控制器;当电压低于电压预设值时或当电流大于预设静态电流值时,控制器控制仪表显示单元进行报警提醒;采用以上技术方案,能够实时检测电动车中的整车低压电路情况,从而及时提示用户进行保养或维修,提高电动车的使用体验感和寿命。
