    Abstract: A system and method for providing a user of a hybrid electric vehicle (HEV) more flexibility and control regarding the selection of heating modes, without adversely affecting vehicle engine emissions. According to one embodiment, when the HEV is in a normal heating mode, the user is able to switch to an economy or deferred heating mode, so long as the switch takes place during the following ignition cycle. When the HEV is in an economy heating mode the user is able to switch to a normal heating mode right away, but is only allowed to do so once per ignition cycle. In both instances, the switch between heating modes is initiated by the user through a non-emissions related system, such as a vehicle infotainment module or climate control module.

    Abstract translation: 一种用于为混合电动车辆（HEV）的用户提供关于加热模式的选择的更多灵活性和控制而不会不利地影响车辆发动机排放的系统和方法。 根据一个实施例，当HEV处于正常加热模式时，只要开关在随后的点火循环期间发生，用户就能切换到经济或延迟加热模式。 当HEV处于经济加热模式时，用户可以立即切换到正常加热模式，但只能在点火循环中进行一次。 在这两种情况下，加热模式之间的切换由用户通过诸如车辆信息娱乐模块或气候控制模块的非排放相关系统启动。

    Abstract: A method of identifying a non-communicative battery Cell Sensing Board (CSB) within a plurality of battery CSBs arranged in a serial chain includes sequentially reconfiguring the serial chain of the battery CSBs to sequentially define each of the plurality of battery CSBs as a last battery CSB in a temporary test serial chain. Communication with the last battery CSB of each temporary test serial chain is sequentially established with a loopback feature of the battery CSBs. When a disruption in communication between the battery system manager controller and the last battery CSB of the current temporary test serial chain is detected, the last battery CSB of the current temporary test serial chain is identified as the non-communicative battery CSB.

    Abstract: A method of controlling positive and negative contactors in a high voltage electrical system includes sensing current flowing through each contactor prior to opening of the contactor and/or after closing of the contactor. A negative contactor weighted value is computed based at least partially on the sensed current flowing through the negative contactor during opening and/or closing. A positive contactor weighted value is computed based at least partially on the sensed current flowing through the positive contactor during opening and/or closing. The order of opening and/or closing of the contactors is determined utilizing at least one of the negative contactor weighted value and the positive contactor weighted value.

    Abstract: Presented are traction battery pack balancing systems, methods for making/operating such systems, and multi-pack, electric-drive motor vehicles with battery pack balancing capabilities. A method for controlling operation of a motor vehicle includes a vehicle controller: receiving a key-off command signal to power off the motor vehicle; determining if a difference between corresponding electrical characteristics of first and second traction battery packs is greater than a calibrated characteristic differential threshold; determining if a difference between corresponding battery pack capacities of the first and second traction battery packs is greater than a calibrated capacity differential threshold; and, responsive to the characteristic difference not being greater than the calibrated characteristic differential threshold and the capacity difference being greater than the calibrated capacity differential threshold, transmitting a key-on command signal to power on the motor vehicle, and a pack balancing command signal to reduce the capacity difference to below the calibrated capacity differential threshold.
