Abstract

Disclosed herein is a charge controlling system, including: a control apparatus; and a plurality of battery units connected to the control apparatus, wherein the control apparatus includes an acquisition section configured to acquire sensor information from at least one of the battery units, and a control section configured to set a magnitude of charge current for each of the battery units in response to the sensor information, and the battery units individually include a battery, a charge controlling section configured to charge the battery with the charge current of the magnitude set by the control section, and a sensor for acquiring the sensor information.

Claims

1. A charge controlling system, comprising:

a control apparatus; and

a plurality of battery units connected to the control apparatus, wherein

the control apparatus includes

an acquisition section configured to acquire sensor information from at least one of the battery units, and

a control section configured to set a magnitude of charge current for each of the battery units in response to the sensor information, and

the battery units individually include

a battery,

a charge controlling section configured to charge the battery with the charge current of the magnitude set by the control section, and

a sensor for acquiring the sensor information.

2. The charge controlling system according to claim 1, wherein the sensor is a temperature sensor for measuring a temperature.

3. The charge controlling system according to claim 2, wherein the control section executes:

first control for reducing charge current of the battery unit whose temperature information obtained by the temperature sensor is higher than a reference temperature; and

second control for increasing charge current to at least one battery unit whose temperature information is lower than the reference temperature together with the first control.

4. The charge controlling system according to claim 1, wherein the battery units individually include:

a conversion section configured to convert a voltage supplied thereto from the outside into a predetermined voltage; and

the sensor is attached to at least one of a position in the proximity of the battery, another position in the proximity of the charge controlling section and a further position in the proximity of the conversion section.

5. A charge controlling apparatus, comprising:

an acquisition section configured to acquire sensor information from at least one of a plurality of battery units; and

a control section configured to set a magnitude of charge current for each of the battery units in response to the sensor information.

6. A charge controlling method, comprising:

acquiring sensor information from at least one of a plurality of battery units; and

setting a magnitude of charge current for each of the battery units in response to the sensor information.

7. A discharge controlling apparatus, comprising:

a temperature information acquisition section configured to acquire temperature information from at least one of a plurality of battery units; and

a control section configured to decrease an output amount of a predetermined battery unit whose temperature information is higher than a reference temperature but increase an output amount of a different battery unit whose temperature information is lower than the reference temperature,

wherein the control section controls the different battery unit such that the increased output amount is greater than the decreased output amount.
