Patent number: 10766378Abstract: An ECU is configured to perform output restriction control if first and second conditions are satisfied when a cell temperature is more than a threshold temperature determined based on a thermal destruction temperature of a sealing member. On the other hand, the ECU is configured not to perform the output restriction control if one of the first and second conditions is not satisfied even when the cell temperature is more than the threshold temperature. The first condition is satisfied when an acceleration time period is more than a predetermined time period. The second condition is satisfied when the temperature increase ratio of the cell is more than a restriction value.Type: GrantFiled: December 18, 2018Date of Patent: September 8, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Hiroyuki Obata
