Abstract: An electrical storage system includes a main battery, an auxiliary battery, a bidirectional DC-DC converter and a controller. The bidirectional DC-DC converter is provided between the auxiliary battery and a power supply path from the main battery to a driving motor. The bidirectional DC-DC converter steps down an output voltage from the power supply path to the auxiliary battery, and steps up an output voltage from the auxiliary battery to the power supply path. The controller controls charging and discharging of the auxiliary battery. The controller, when an allowable output power of the main battery decreases and an electric power becomes insufficient for a required vehicle output, supplies an electric power to the power supply path by discharging the auxiliary battery by using the bidirectional DC-DC converter. The controller, when an allowable input power of the main battery decreases and a regenerated electric power generated by the driving motor is not entirely charged into the main battery, charges part of the regenerated electric power into the auxiliary battery by using the bidirectional DC-DC converter.

Abstract: A vehicle includes a generator, an engine, a main battery, an auxiliary battery, and a controller. The engine is configured to perform a load operation and a self-supported operation. The controller is configured to control charging and discharging of the auxiliary battery. When an upper limit of an allowable charging power of the main battery decreased and a command power is in a state in which the load operation and the self- supported operation are alternately switched, the controller is configured to operate a continuous charging. The continuous charging is to charge the auxiliary battery continuously for a predetermined time with a charging power. The charging power is a power which increases the command power to be equal to or larger than the threshold.

Abstract: A secondary battery system includes an assembled battery that includes a plurality of blocks that are connected in series to one another. Each of the plurality of the blocks includes same number of cells that are connected in parallel to one another. A control device is configured to calculate an internal resistance ratio and a protection current. The internal resistance ratio is a value obtained by dividing the higher one of internal resistances by the lower one of the internal resistances of two of the plurality of the blocks. The protection current is a value obtained by multiplying the internal resistance ratio by a current value of the assembled battery detected by a current sensor. The control device is configured to perform the charge-discharge control based on the protection current.
