    摘要： Embodiments discussed herein refer to backwards compatible charging circuits and methods for charging a battery to a relatively high voltage level regardless of whether the charging station is capable of supplying power at that relatively high voltage level. The circuitry and methods according to embodiments discussed herein can use the onboard charging system to provide a voltage boosting path to increase the charge voltage from a legacy voltage level (e.g., a relatively low voltage level) to a native voltage level (e.g., a relatively high voltage level). When a native voltage charging station is charging the battery, the circuitry and methods according to embodiments discussed herein can use a native voltage path for supplying power, received from the charging station at the native voltage, to the battery.

    摘要： A powertrain backlash control system is provided for use with an electric vehicle (EV), where the EV uses at least one powertrain to provide forward vehicle motion and at least one additional powertrain to provide rearward vehicle motion. The control system eliminates backlash by maintaining a positive motor torque within each powertrain when the vehicle is in-gear, thus applying a minimum forward torque demand to the powertrain dedicated to forward motion and applying a minimum reverse torque demand to the powertrain dedicated to rearward motion.

    摘要： A battery cell balancing and measuring apparatus is provided. The apparatus includes a plurality of terminals having a portion of the terminals grouped as terminal pairs, each terminal of the plurality of terminals operable to couple to a node in a battery stack. Each terminal pair having a capacitor and a switch coupled in parallel with each other, the capacitor and the switch coupled across respective terminal pair. The apparatus includes a plurality of resistors, each resistor of the plurality of resistors coupled to a terminal of the plurality of terminals. Each resistor of the plurality of resistors provides a discharge path for a respective battery cell coupled to a terminal pair via the switch and wherein each resistor of the plurality of resistors provides a low pass filter path for the respective battery cell via the capacitor.
