摘要： A battery system and a method include an auxiliary power module configured to support auxiliary loads. A first contactor switch connected between first and second battery packs, and a second contactor switch is in series with the first contactor switch. A controller determines whether to open or close first and second contactor switches depending on whether the battery packs are being charged in a high voltage mode or a low voltage mode. The contactor switches are both closed when in the high voltage mode and at least one of the contactor switches is opened when in the low voltage mode. At least one of the first and second battery packs operate to power the auxiliary power module while charging at least one of the first and second battery packs regardless of whether the battery packs are in the high voltage mode or the low voltage mode.

摘要： A battery module for an electric vehicle includes an auxiliary power module (APM) and at least one battery pack assembly. The battery pack assembly includes a plurality of battery frames, each with at least one battery cell disposed within it, and a plurality of cooling plates, each in thermal communication with at least one battery cell. The cooling plates have an inlet and an outlet connected by at least one coolant channel through which coolant is circulated to cool the battery cells. The APM may also require cooling, in which case the battery module may further include at least one additional cooling plate in thermal communication with the APM. The APM and the battery pack assembly are held together under compression such that they may share a common cooling system, and coolant may flow through the APM and/or the battery pack assembly to the cooling plates.

摘要： A method and system for controlling one or more contactors of a rechargeable energy storage system (RESS) includes adjusting, via a controller, the respective actuating power provided to a respective one or more of the contactors, where adjusting of the actuating power is defined by the energized or non-energized condition of the vehicle and at least one parameter affecting holding and opening forces exerted on the respective contactor. In an example, the controller is configured to use feed forward factors defined by the at least one parameter and to adjust the dynamic actuating current by modulating the dynamic actuating current at a pulse width modulation (PWM) frequency defined by a feed forward window. The system may be configured as a plug-in electric vehicle including the rechargeable energy storage system and the controller.

The alarm system includes a battery, a charge cord sensor, a battery state estimator (“BSE”) module, and an interface module. The battery has state of charge (“SOC”), and is rechargeable to a predetermined level of charge. The charge cord sensor is configured to detect if the vehicle charge cord is connected to or disconnected from a vehicle. The BSE module is configured to monitor the SOC of the rechargeable battery and determine if the battery is charged to the predetermined level of charge. The interface module is in communication with the charge cord sensor and the BSE module. The interface module is configured to switch the alarm system from the armed state to the disarmed state.

摘要： A battery system is electrically connected to a power bus that is arranged to supply electric power to an on-vehicle actuator such as an electric traction machine. Controlling electric power flow in the battery pack includes determining states of charge for the plurality of battery packs, identifying one of the battery packs as a weakest battery pack based upon the states of charge, and determining an internal circulating current being transferred via the wiring harness that is associated with charging of the weakest battery pack. Electric power transfer through the wiring harness and the power bus is controlled such that the internal circulating current is less than an internal circulating current limit. In one embodiment, the internal circulating current limit is determined in relation to battery temperature.
