Abstract
Provided is an electric power control apparatus capable of suppressing charge/discharge with respect to an electrical storage device under an anomalous condition. The electric power control apparatus includes an electrical storage device including electrical storage modules, a module-temperature detection section, a temperature-condition judgment section, an adopted-module-temperature selection section, and a charge/discharge-electric-power-upper-limit setting section. The temperature-condition judgment section makes a judgment on a temperature condition of the electrical storage device based on a temperature detected by an electrical-storage-device temperature detection section. The charge/discharge-electric-power-upper-limit setting section sets charge/discharge electric power upper limit of the electrical storage device, based on a module temperature (Tmin) which is deviated to a side of a non-steady temperature condition and selected by the adopted-module-temperature selection section, when the electrical storage device is judged to be under the non-steady temperature condition.
