    摘要: A nonaqueous-electrolyte secondary battery charging/discharging method that provides a prolonged cyclic life. In the charging/discharging method, a secondary battery is continuously charged unconditionally until a charging capacity exceeds 20% of a full charging capacity. The charging is completed when the charging capacity exceeds 70% of a full charging capacity. A maintenance charging/discharging operation is performed to avoid the full charging capacity being in an error state when dV/dt exceeds a specified value “a” before a charging current exceeds 70% of the full charging capacity. Likewise, the maintenance charging/discharging operation is performed to avoid the full charging capacity being in an error state when dT/dt exceeds a specified value “b” before a charging current exceeds 70% of the charging capacity.

    摘要: In a battery pack including a battery composed of a plurality of secondary calls, a control device for a protection circuit of the battery from over-charging/discharging is disclosed. A cell voltage detector detects cell voltages of the second cells, respectively, and a battery voltage detector detects a battery voltage of the battery. A controller activates a circuit breaker to break an input/output circuit of the battery when the battery voltage does not match a total cell voltage obtained by adding the cell voltages.
