MANAGEMENT DEVICE FOR SECONDARY BATTERY |
| 摘要 |
A battery management device for a battery that is incorporated in a vehicle includes a cooling fan configured to cool the battery and a controller configured to control the cooling fan. The controller is configured to calculate an amount of high-rate degradation damage which is an amount of degradation damage to the battery caused by high-rate charge or discharge, and is configured to restrict cooling of the battery by the cooling fan when the amount of high-rate degradation damage has reached or exceeded a predefined cooling restriction starting threshold, more strictly than when the amount of high-rate degradation damage is less than the cooling restriction starting threshold. |

1. A secondary battery management device for a secondary battery that is incorporated in a vehicle, the secondary battery management device comprising:
a cooling mechanism configured to cool the secondary battery; and a controller configured to control the cooling mechanism, wherein the controller is configured to calculate an amount of high-rate degradation damage which is an amount of degradation damage to the secondary battery caused by high-rate charge or discharge, and is configured to restrict cooling of the secondary battery by the cooling mechanism when the amount of high-rate degradation damage has reached or exceeded a predefined cooling restriction starting threshold, more strictly than when the amount of high-rate degradation damage is less than the cooling restriction starting threshold. |
