摘要：
Systems and methods for sensing internal states of vehicle batteries are described. From this internal state information, various physical characteristics of the battery can be measured, calculated or inferred. A vehicle can include an electric motor, a battery to store electrical energy for the electric motor, and a sensor connected to the battery to sense a battery state, to receive an input signal, and to wirelessly transmit an output signal indicating the battery state. The sensor may be passive and built into the structure of the battery. The sensor can be a surface wave acoustic sensor with a magnetic field sensor, which can be a magnetoimpedance sensing device and a temperature sensor.
