Patent
Proterra | Date: 2017-03-15

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


Patent
Proterra | Date: 2015-12-23

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.

An embodiment of the invention provides a method of charging an energy storage system for an electric vehicle. The method includes determining the estimated consumption for a specific route of the electric vehicle at different times and setting a target end point for the energy storage system based upon a minimum state of charge level for the energy storage system. The method further includes determining charge set points for the energy storage system based upon the target end point and the determined estimated consumption and determining the actual end point of the energy storage system after operation of the electric vehicle on the given route. The method also includes comparing the actual end point to the target end point and determining the difference in state of charge for the energy storage system between the actual end point and the target end point. In addition, the method includes using the difference between the actual end point and the target end point to adjust the charge set points for the energy storage system.
