摘要： The electric leakage detection method disclosed herein is first detection of turning at least one of the positive-side contactor or the negative-side contactor ON and detecting a value of a system electric leakage resistor RZ which is an electric leakage resistance of the entire electricity distribution system; second detection of turning both of the positive-side contactor and the negative-side contactor OFF and detecting a value of a power source-side electric leakage resistor RL which is an assembled battery 10-side electric leakage resistance; and first determination of determining which of the power source unit-side region or the electric device-side region is causing the electric leakage based on the values of the system electric leakage resistor RZ and power source-side electric leakage resistor RL.

摘要： A battery system includes a plurality of battery units connected in parallel, a battery unit voltage detector detecting a voltage value of the battery units, a plurality of unit relays respectively connected in series to the plurality of battery units, and at least one balancing circuit. The battery units each includes a plurality of battery cells connected in series, a cell voltage detector, and an equalizer equalizing remaining capacities of the plurality of battery cells. The balancing circuit includes a resistor. One end of the balancing circuit is connected to a connection point between one of the battery units and one of the unit relays that are connected in series. The other end of the balancing circuit is connected to a connection point between another one of the battery units and another one of the unit relays that are connected in series.

摘要： A battery system includes: an battery assembly; a controller; and a voltage sensor, a first temperature sensor, and a second temperature sensor, which are a plurality of sensors that each detects a parameter of the battery. An abnormality of a sensor of the plurality of sensors does not lead to an abnormality of a remainder of the sensors. The controller determines that the battery assembly is abnormal when at least two sensors of the plurality of sensors output abnormal values.

摘要： The electric leakage detection method disclosed herein includes: total voltage measurement of measuring a total voltage Vt which is an electrical potential difference between a total positive terminal open to be connectable with an external device and a total negative terminal open to be connectable with the external device; electric leakage voltage measurement of measuring an electric leakage voltage VL which is an electrical potential difference between a reference terminal (the total negative terminal) and the electric leakage occurring position (the third single battery); and an electric leakage occurring position determination of determining the electric leakage occurring position by calculating a ratio (VL/Vt) of the electric leakage voltage VL to the total voltage Vt. This allows the number of single batteries between the reference terminal and the electric leakage occurring position to be estimated, and a detailed electric leakage occurring position to be determined.
