A battery monitoring system for a vehicle includes a processor and a memory. The memory stores instructions for causing the processor to estimate a state of charge of the battery based on a current cell pressure of the battery when the state of charge of the battery is below a threshold state of charge and to estimate the state of charge of the battery based on a voltage output by the battery when the state of charge of the battery is greater than or equal to the threshold state of charge.
一种用于车辆的电池监测系统包括处理器和存储器。存储器存储用于使处理器在电池的电量状态低于阈值电量状态时基于电池的当前电池单元压力来估计电池的电量状态以及在电池的电量状态大于或等于阈值电量状态时基于由电池输出的电压来估计电池的电量状态的指令。
