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: An ECU executes a charge preparation communication sequence after a connector is connected to an inlet and before external charging is performed, and counts a response time (message transmission and reception time) of a charging station to a prescribed event. A memory stores a message transmission and reception time of a specific charging station. The ECU does not perform external charging when the message transmission and reception time counted during the charge preparation communication sequence is equal to the message transmission and reception time stored in the memory.

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.
Abstract: A vehicular charging control system using a solar panel includes: a first battery; a calculation unit that calculates a chargeable electric power amount (an amount of electric power with which the first battery can be charged until the SOC of the first battery reaches a predetermined value); a determination unit that determines whether regenerative electric power is being generated; and a control unit that controls charging of the first battery with electric power generated by the solar panel. The control unit allows the first battery to be charged with the electric power generated by the solar panel up to an upper limit set to the chargeable electric power amount when regenerative electric power is not being generated, and up to an upper limit set to an electric power amount obtained by subtracting the regenerative electric power amount from the chargeable electric power amount when regenerative electric power is being generated.
