Abstract: A battery control device capable of obtaining an allowable charge/discharge current value can further accurately reflect a polarization state of a battery. A battery controller includes a first allowable current value calculation unit, a battery equivalent circuit model, and a correction amount calculation unit. Assuming a non-polarization state, a current limit value of the battery based on an open circuit voltage and upper and lower limit voltages set in the battery, the first allowable current value calculation unit calculates a first allowable current value Imax1. The battery equivalent circuit model estimates a polarization state of the battery when the current limit value is being calculated. The correction unit calculates an allowable current value correction value based on the estimated polarization state for correcting Imax1. A second allowable current value Imax2 which is the corrected first allowable current value is output as an allowable charge/discharge current value of the battery.

Abstract: The vehicle battery pack exchange system herein described charges renters for the time use interval, the energy needed to recharge the battery pack, and the battery wear their use has caused. Data on battery wear accelerating stress parameters such as current, voltage, temperature, and state of charge is collected for battery packs rented to vehicle users. Wear rates are estimated from the collected data. Then either users are charged for the wear they cause or wear is limited to some predetermined wear rate and users are charged a predetermined battery wear fee per kWh delivered by the battery pack. In either embodiment drivers are displayed information to adapt their driving to battery wear rates. Renters are charged for battery pack usage time, energy supplied by the rental station, and battery wear providing battery owners a secure return on their investment. This system accommodates both short term and sustained long term rentals.
