COOLING SYSTEM FOR VEHICLE-MOUNTED SECONDARY BATTERY |
| 摘要 |
A cooling system for cooling a main battery 10 includes a cooling fan 40 and a temperature sensor 61 configured to detect a battery temperature TB. The cooling system performs constant control in which the cooling fan 40 is driven at a constant command value when the battery temperature TB reaches or exceeds a first temperature T0 after startup of the electrically powered vehicle. Additionally, the cooling system detects whether or not a malfunction occurs in the cooling fan 40, based on an actual rpm of the cooling fan 40 obtained during the constant control. The cooling system performs the constant control in a situation in which charging of the main battery 10 is continued for a predetermined period of time or longer after the startup of the vehicle, regardless of whether the battery temperature TB is below the first temperature T0. |

1. A cooling system for cooling a vehicle-driving secondary battery mounted in an electrically powered vehicle, the cooling system comprising:
a cooling fan configured to supply cooling air to the secondary battery; and a temperature sensor configured to detect a battery temperature representing a temperature of the secondary battery, the cooling system being configured to perform constant control in which the cooling fan is driven at a constant command value for a predetermined period of time when the battery temperature reaches or exceeds a predefined first temperature after startup of the electrically powered vehicle, and configured to perform a malfunction detection process for detecting whether or not a malfunction occurs in the cooling fan, based on an actual rpm of the cooling fan obtained during the constant control, wherein the cooling system performs the constant control in a situation in which charging of the secondary battery is continued for a predetermined period of time or longer after the startup of the electrically powered vehicle, regardless of whether the battery temperature is below the first temperature. |
