Abstract: The vehicle includes a powertrain having an axle having a first drive wheel and a second drive wheel. A first gearbox may couple a first power source to the first drive wheel, and a second gearbox may independently couple a second power source to the second drive wheel. And, a controller may be configured to initiate a gear shift in the first gearbox and the second gearbox at different times.

Abstract: The invention provides for a high occupancy or heavy-duty vehicle with a battery propulsion power source, which may include lithium titanate batteries. The vehicle may be all-battery or may be a hybrid, and may have a composite body. The vehicle battery system may be housed within the floor of the vehicle and may have different groupings and arrangements.

Abstract: Systems and methods for charging an electric bus having a charging interface on its roof may include determining that an approaching bus is supposed to be charged at the charging station, lowering the charging head of the charging station to land on the roof of the bus, and moving the bus with the charge head on its roof to engage the charging head with the charging interface.

Abstract: A battery system may include a controller and multiple parallel connected battery strings, with each string including at least one battery, a passive overcurrent protection device and an active overcurrent protection device. The passive overcurrent protection device may be configured to disconnect the string from the battery system when an electrical current in the string exceeds a first threshold value, and the active overcurrent protection device may be configured to disconnect the string from the battery system upon activation by the controller. The controller may be configured to (a) activate a first active overcurrent protection device of a first string of the multiple strings at a first time, and (b) activate a second active overcurrent protection device of a second string of the multiple strings at a second time different from the first time.

Abstract: A method of charging an electric vehicle at a charging station includes electrically connecting the charging station to the vehicle. The charging station may be configured to charge the vehicle using a charging station charge protocol and the vehicle may be configured to receive the charge using a vehicle charge protocol. The vehicle receives a signal indicative of the charging station charge protocol and selects the vehicle charge protocol based on this signal. The vehicle is then charged using the selected vehicle charge protocol. While selecting, the vehicle may select one charge protocol from multiple charge protocols supported by the vehicle to match the charging station charge protocol.

Abstract: An electric vehicle charging system includes a charging interface positioned on an external surface of the electric vehicle and one or more electrodes positioned on the charging interface. The charging system may also include a heating system positioned on the charging interface. The heating system may be configured to heat at least a portion of the charging interface. The charging system may also include a control system configured to selectively activate the heating system based at least on one or more ambient conditions.

Abstract: The vehicle includes a powertrain having an axle having a first drive wheel and a second drive wheel. A first gearbox may couple a first power source to the first drive wheel, and a second gearbox may independently couple a second power source to the second drive wheel. And, a controller may be configured to initiate a gear shift in the first gearbox and the second gearbox at different times.

Abstract: A battery system for an electric vehicle includes a first battery module with a first heater and a second battery module with a second heater. The battery system also includes a control system configured to selectively activate the first or the second heater to dissipate energy from the first or the second battery module.

Abstract: The power train of an electric vehicle includes an electric motor and a gearbox coupling the electric motor to a drive wheel. A controller may be configured to initiate a gear shift in the gearbox, and activate one or both of (a) a torque jog in electric motor, or (b) a burst of a pressurized fluid in an actuator to assist with the gear shift.

Abstract: A method for charging an electric vehicle using charge current from a charging source. The charge current is determined based at least on the state of charge of the electric vehicle and a chemistry or type of the battery system.

Abstract: The invention relates to systems and methods for charging a vehicle. A vehicle and charging station can be designed such that an electric or hybrid vehicle can operate in a fashion similar to a conventional vehicle by being opportunity charged throughout a known route.

Abstract: A method of charging an electric vehicle includes receiving data indicative of the power source system voltage during charging, determining a maximum voltage limit of the power source, and setting the maximum voltage limit as the limiting voltage of the power source. The maximum voltage limit may be the maximum permissible value of the system voltage during the charging.
