    摘要： A total SOC of a battery pack including a collection of a plurality of battery blocks is calculated based on a plurality of block SOCs representing respective stored charge amounts in the plurality of battery blocks. In the case (401) where a block SOC maximum value (BSmax) is higher than a control upper limit value (SOCu), the total SOC is calculated to be higher than the control upper limit value. On the other hand, in the case (402) where a block SOC minimum value (BSmin) is lower than a control lower limit value (SOCl), the total SOC is calculated to be lower than the control upper limit value. Further, in the case (403) where each of the block SOCs is in a range of not less than the control lower limit value and not more than the control upper limit value, the total SOC is determined to fall within the range of not less than the control lower limit value and not more than the control upper limit value.

    摘要： An electric vehicle is provided with a cell voltage sensor (32) and a cell temperature sensor (31) which are mounted to each of a plurality of cells (21); a gas temperature sensor (33), a carbon monoxide gas sensor (34), and a hydrogen gas sensor (35) which are mounted to a chamber (27); a gas temperature sensor (36), a carbon monoxide gas sensor (37), and a hydrogen gas sensor (38) which are mounted to a gas exhaust passage (28); and an air-conditioning fan (17), a channel-switching damper (19), and adrivingmotor (42) which lowers a window glass (41). When battery state values detected by the sensors (31) to (38) exceed predetermined thresholds, a battery pack (20) is judged to be abnormal. Then, the channel-switching damper (19) and the air-conditioning fan (17) are started and the window glass (41) is lowered to ventilate the vehicle interior. This speedily exhausts smoke generated from a lithium ion battery.

    摘要： The present teaching provides a technique for detecting a failure in a switching device early in a power supply system including a plurality of sweep modules. A power supply system 1 disclosed here is connected to an electric power system through a distribution device. The power supply system includes a plurality of strings connected to the distribution device and a failure detector. The failure detector of the power supply system is configured to perform a first process of connecting at least one battery module to a main line to set a voltage detected by a string voltage detector at a voltage higher than a predetermined voltage in a state where a switch disconnects the distribution device and the main line, a second process of sending a disconnecting signal for disconnecting all the sweep modules from the main line, and a third process of determining whether the voltage detected by the string voltage detector is lower than the predetermined determination voltage or not after the second process.
