Proterra | Date: 2015-12-10

A heavy-duty electric vehicle having a pneumatic brake may include at least one electric motor configured to propel the vehicle, and a battery system configured to provide power to the at least one electric motor. The battery system may be configured to be recharged by regenerative braking of the vehicle. The vehicle may also include a braking system. The braking system may be configured to (a) apply substantially only regenerative braking to slow the vehicle during initial slowdown and (b) subsequently apply both regenerative braking and pneumatic braking after the initial slowdown.

A method of docking an electric vehicle at a charging station may include identifying the vehicle as it approaches the charging station and transmitting a distance parameter from the charging station to the vehicle. The distance parameter may be a measure of distance. The method may also include determining a desired speed of the vehicle based on the distance parameter using an algorithm in the vehicle, and controlling the vehicle to attain the determined desired speed.

A method for controlling the charging of multiple electric vehicles operating in a geographic area may include inputting a tariff schedule into a control system. The tariff schedule may identify the cost of energy at different times in the geographic area. The method may also include receiving data from the multiple electric vehicles. The data may include at least the state of charge of the vehicle. The method may further include sending instructions to at least one vehicle of the multiple electric vehicles. The instructions may include directives on charging based at least on the tariff schedule and the received data.

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.


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.
