Abstract: A charging assembly, an electric vehicle including the charging assembly and a method for charging an electric vehicle battery are provided. In a method for charging the battery that has a rated voltage that is greater than the charging voltage of a charging station, first and second battery units of the battery are configured in a series configuration. The method then supplies the charging voltage to the battery while the first and second battery units are in the series configuration to charge the battery. The method thereafter discontinues supply of the charging voltage to the battery prior to charging the battery to the rated voltage. After discontinuing the supply of the charging voltage to the battery, the method configures at least the first and second battery units in a parallel configuration and then supplies the charging voltage of the charging station to the battery to further charge the battery.

Abstract: A battery cooling system may include a battery housing configured to be coupled to a chassis of the battery electric vehicle. A battery cooling system may include a plurality of battery cells positioned within the battery housing, each of the plurality of battery cells including a pole. A battery cooling system may include a liquid cooling plate arranged in thermal communication with the poles of the plurality of battery cells. A battery cooling system may include a liquid cooling system providing coolant to the liquid cooling plate. A battery cooling system may include an airflow passageway defined between the battery housing and the plurality of battery cells. A battery cooling system may include a vehicle heating, ventilation, and air conditioning (HVAC) system providing cooled air to the airflow passageway.

Abstract: A software calibration strategy for calibrating solenoid controlled valves and valve systems in an automatic transmission. The strategy includes identifying a characteristic equation for the valve or valve system that is a mathematical relationship between a current applied to the solenoid and the pressure at the output of the valve or valve system. The valve or valve system is coupled to a test stand that depicts the operation of the valve or valve system in the transmission. Current signals are applied to the valve or valve system, and the output pressures are measured to determine coefficients in the equation using a curve fitting function. The coefficients are then stored in a control unit.

Abstract: An electrohydraulic transmission control apparatus (10) that produces, controls and directs hydraulic pressure inputs to the clutches, brakes and shift mechanisms of an automatic transmission to shift the transmission. A module body (14) supports control apparatus components and is removably mountable to a transmission housing (16) of the transmission. The module body (14) defines a plurality of fluid conduits (28). A plurality of control valves (26) is disposed on the module body (14) and meter hydraulic fluid through the conduits (28) to brake and clutch hydraulic cylinders and shift mechanisms in the transmission. A plurality of solenoid-operated control valves (26) is also disposed on the module body. A controller (34) disposed on the module body is connected to the solenoids (30) and controls the valves by operating the solenoids (30) in accordance with inputs received from sensors (36-44) that detect various factors representing the running state of the transmission and the vehicle it's mounted in.
