Abstract:
1. An apparatus for controlling an output of a secondary battery, comprising: a voltage measuring section for measuring a terminal voltage of a secondary battery as voltage data; and an output limiting section for limiting discharging of the secondary battery so as not to exceed a limit value of output electric power and for changing the limit value of output electric power when the voltage data from the voltage measuring section reaches a predetermined discharging termination voltage, wherein the output limiting section has short-time output information for setting operation to allow short-time discharging at higher power of the secondary battery and normal output information for setting operation to allow long-time discharging at lower power of the secondary battery, the discharging termination voltage comprises a first discharging termination voltage during short-time discharging under the operation with the short-time output information and a second discharging termination voltage during long-time discharging under the operation with the normal output information, and the first discharging termination voltage being set to be lower than the second discharging termination voltage.
