Abstract
A charging control method for controlling charging of a secondary battery includes: an acquisition step of acquiring information on heat of the secondary battery; and a control step of setting, based on the information on the heat of the secondary battery, a charging current value of the secondary battery to control an amount of heat generation by the secondary battery to a predetermined value.
Claims7
A charging control method for controlling charging of a secondary battery, the method comprising:
- an acquisition step of acquiring an operation state of a cooling system for the secondary battery and at least one of a temperature of the secondary battery, an amount of heat generation by the secondary battery, and an amount of heat dissipation from the secondary battery as information on heat of the secondary battery;
- and
- a control step of setting, based on a change in the information on the heat, a charging current value of the secondary battery to control the amount of heat generation by the secondary battery to a predetermined value, wherein
- in the control step, when the charging current value of the secondary battery is decreased in accordance with a change in the acquired temperature, the acquired amount of heat generation or the acquired amount of heat dissipation of the secondary battery, a set value of the charging current value when a supply of refrigerant to the secondary battery is limited during an operation of the cooling system is set relatively smaller than a set value of the charging current value when the supply of refrigerant is not limited.

A charging control system comprising:
- a secondary battery;
- and
- a controller configured to control charging of the secondary battery, wherein
- the controller acquires an operation state of a cooling system for the secondary battery and at least one of a temperature of the secondary battery, an amount of heat generation by the secondary battery, and an amount of heat dissipation from the secondary battery as information on heat of the secondary battery,
- the controller executes a control process of setting, based on a change in the acquired information on the heat, a charging current value of the secondary battery to control the amount of heat generation by the secondary battery to a predetermined value, and
- in the control process, when the charging current value of the secondary battery is decreased in accordance with a change in the acquired temperature, the acquired amount of heat generation or the acquired amount of heat dissipation of the secondary battery, a set value of the charging current value when a supply of refrigerant to the secondary battery is limited during an operation of the cooling system is set relatively smaller than a set value of the charging current value when the supply of refrigerant is not limited.
