ELECTRIC VEHICLE BATTERY MONITORING SYSTEM

Systems and methods for monitoring and controlling a battery are disclosed. Systems can include a battery having an output voltage and an output current when delivering power, a load driven by power delivered from the battery, battery output voltage and current sensing circuits, and processing circuitry coupled to the battery output voltage and current sensing circuits. The processing circuitry may be configured to obtain sensed battery output voltage and current values, and to estimate values for at least three battery state parameters by concurrently fitting the voltage and current values toat least two different equations. 公开了用于监测和控制电池的系统和方法。系统可包括在输送电力时具有输出电压和输出电流的电池，由从电池输送的电力驱动的负载，电池输出电压和电流感测电路，以及耦合到电池输出电压和电流感测电路的处理电路。处理电路可以被配置为获得感测的电池输出电压和电流值，并且通过将电压和电流值同时拟合到至少两个不同方程来估计至少三个电池状态参数的值。
