摘要： A method includes implementing an inverted degradation model to determine an optimal battery core temperature. The inverted degradation model receives as inputs one or more of a power state value indicating whether the battery is currently in a high-power state or a low power state, a battery temperature value representing a current battery core temperature, a battery degradation value representing a battery degradation status, a battery age indicator representing a current age of the battery, a state of charge value representing a remaining battery charge and a battery current load value representing a current draw from the battery by the electric vehicle. The inverted degradation model outputs a desired battery core temperature value. The method includes operating the battery thermal system in order to achieve the desired battery core temperature.

摘要： A motor control system to be applied to an electric vehicle includes a battery, a motor including a rotor and a stator, two inverter circuits, one or more processors, and a cooling water circuit including a cooling water pump. The motor control system includes motors each being the motor and pairs of two inverter circuits each being the two inverter circuits. The stator of each of the motors is coupled to the two inverter circuits of a corresponding one of the pairs of two inverter circuits. The one or more processors drive the cooling water pump to circulate cooling water, and drive each of the two inverter circuits to apply oppositely directed rotational torques to the rotor, to warm up the battery. While warming up the battery, the one or more processors switch, at predetermined timing, which of the motors to allow to generate heat.

摘要： A thermal management system includes a first cooler that cools a first heat source, a first circulation path that connects the first cooler and a first pump, a second cooler that cools a second heat source, a second circulation path that connects the second cooler and a second pump, a changeover valve, and a controller. The changeover valve is switchable between first and second valve positions. The first and second circulation paths are separated from each other when the changeover valve is in the first valve position. The controller causes both the first and second pumps to operate when the temperature difference between refrigerants in the first and second circulation paths is more than a predetermined temperature difference threshold when the changeover valve is set to the first valve position and one of the first and second pumps is operating and the other is not operating.

摘要： A management system for a multi-cell rechargeable energy storage system (RESS) is capable of wirelessly communicating with an unsecured third-party device. The management system includes a system controller that is in communication with cell monitoring units that are arranged to individually monitor the battery cells. Each cell monitoring unit includes a cell controller that is in communication with a sensor that is arranged to determine a parameter of a respective one of the battery cells of the RESS. Each of the cell controllers is configured to execute a secure wireless communication protocol, and is also configured to execute an open wireless communication protocol. The open wireless communication protocol is activated to enable non-proprietary wireless communication to a proximal third-party device in response to a trigger event.
