摘要： A method monitors the functional capability of the cooling system of an operating high-voltage accumulator for an electric drive unit of a motor vehicle. The method repeatedly measures the temperature of the high-voltage accumulator by use of a temperature sensor mounted on the high-voltage accumulator; checks whether the measured temperature value is above a cooling threshold temperature; determines a profile of the temperature of the high-voltage accumulator using a temporal sequence of the measured temperature values of the high-voltage accumulator which are above the cooling threshold temperature; and diagnoses that the cooling system is operating correctly if the temperature profile does not exceed a predetermined threshold.

摘要： A battery cooling system includes a cooling fan that takes in inside air of a vehicle cabin to an intake passage and sends the air to a battery communicating with the vehicle cabin through the intake passage, a battery temperature sensor that detects a temperature of the battery, an intake air temperature sensor that is disposed in the intake passage and detects a temperature of the air flowing through the intake passage, and a controller. The controller controls the cooling fan based on the detected temperatures. The controller performs a temperature check operation. Firstly, when the difference value between the detected temperatures is larger than zero, the controller repeats the temperature check operation. Afterward, When the difference value in the latest temperature check operation is smaller than the difference value in the previous temperature check operation and larger than zero, the controller repeats the temperature check operation.

摘要： A vehicle includes an electric machine, a battery, an accelerator pedal, a battery cooling system, and a controller. The electric machine is configured to propel the vehicle. The battery is configured to provide electrical power to the electric machine. The battery cooling system is configured to cool the battery in a plurality of cooling modes. A transition between cooling modes of the battery cooling system corresponds to either an increase or a decrease in battery power being utilized to cool the battery. The controller is programmed to truncate an acceleration request under certain conditions to prevent an increase in battery power output in order to reduce a rate at which the battery temperature increases and to prevent a transition to a cooling mode that requires an increase in battery power output.
