A server, an apparatus and a method for determining an impact on components of a temperature-controlled unit of a vehicle. The method includes receiving information of one or more parameters associated with one or more components of a temperature-controlled unit of a vehicle. Further, the information of the one or more parameters are received in response to a change in acceleration of the vehicle. The method also includes determining an impact on the one or more components of the temperature-controlled unit due to the change in the acceleration. The method further includes transmitting a notification to a device based on the impact on the one or more components of the temperature-controlled unit.

A vehicle system includes an electric motor that also operates as a generator. A torque transfer mechanism is attached to the electric motor and a second torque transfer mechanism is connected via a disconnect mechanism. An AC compressor is attached to the first torque transfer mechanism via a clutch, which has an open position and a closed position. During recuperation, the second torque transfer mechanism is connected to the first torque transfer mechanism and the clutch is closed, and the compressor is driven by the motor. During stand-still, the second torque transfer mechanism is disconnected from the first torque transfer mechanism, and the compressor is driven by the motor. During drive operation, the second torque transfer mechanism is connected to the first torque transfer mechanism, and the clutch is open such that the compressor is not driven, but the system continues to provide cool air to the vehicle cabin.

A method of power demand management is provided. The method includes an electrically powered climate control unit (CCU) detecting one or more additional electrically powered CCUs in a vicinity of the electrically powered CCU and the CCU establishing a communication link with the one or more additional electrically powered CCUs. The method includes generating and transmitting a pending power request to demand power from the power source to the CCU. The CCU monitors for one or more additional pending power requests from the one or more additional CCUs and monitors its position within a power request queue for obtaining power from the power source amongst the CCU and the one or more additional CCUs. Also, the method includes the electrically powered CCU demanding power from the power source when its position within the power request queue is high enough to demand power from the power source.
