摘要： A battery pack cooling system includes a plurality of cells disposed in an internal space of a battery pack case so as to form a cooling passage configured to cool the cell modules by cooling air flowing in the cooling passage. A first temperature sensor is a minimum temperature sensor disposed in the upstream position which becomes a lowest temperature. A second temperature sensor is a maximum temperature sensor disposed in the downstream position which becomes a highest temperature. A third temperature sensor is configured to measure the temperature of either the highest temperature or the lowest temperature disposed in a second cell module. A cooling passage includes a cooling air inlet passage, a cooling air exhaust passage, and a plurality of cooling branch passages disposed to connect the cooling air inlet passage and the cooling air exhaust passage in parallel.

摘要： A battery pack cooling system includes a plurality of cells disposed in an internal space of a battery pack case so as to form a cooling passage configured to cool the cell modules by cooling air flowing in the cooling passage. The cooling passage includes a cooling air inlet passage, a cooling air exhaust passage, and a plurality of cooling branch passages disposed to connect the cooling air inlet passage and the cooling air exhaust passage in parallel. A minimum temperature sensor is disposed in the upstream position to measure a lowest temperature region in a first cell module. A maximum temperature sensor is disposed in the downstream position which becomes a highest temperature region in the first cell module. Another temperature sensor is disposed in a second cell module to measure the temperature of either the highest temperature or the lowest temperature in the second cell module.

摘要： A capacity ratio estimation apparatus and method for a battery detects current and voltage of the battery; specifies an integration period from a first time point to a second time point and calculates an integration value of the current for the integration period based on detected current; calculates a first open circuit voltage at the first time point based on the detected voltage and calculates a second open circuit voltage of the battery at the second time point based on the detected voltage; and estimates a capacity ratio of the battery based on a voltage difference between the first open circuit voltage and the second open circuit voltage and an integration value satisfying predetermined conditions. The integration value is equal to a predetermined lower limit value or greater and an average value of the current of the battery for the integration period is equal to the predetermined value or greater.
