  • Publication number: 20220203837
    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.

  • Publication number: 20220029208
    Abstract: A method, and associated batteries and battery charging units, that involve inducing electric and/or magnetic fields (field-induced current) across an electrode of a electrochemical cell, such as an anode of a battery. The field and current across the electrode may be referred to herein as a transverse current as this current is typically transverse to the ionic charge current that may be applied when charging a battery. The field and current may be induced from connecting AC energy, e.g., AC current, across the electrode or at a discrete point or points of the electrode. The induced field and current may suppress dendrite growth, experienced in conventional batteries without AC energy, among other advantages.

  • Patent number: 10946763
    Abstract: 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.

  • Patent number: 10696174
    Abstract: Systems and methods for enabling fast charging of an electric vehicle at a charging station. An electric vehicle in positioned in a given location for charging and/or discharging. A charging arm comprising a plurality of charging brushes is then positioned relative to the position of the electric vehicle. The plurality of charging brushes on the charging arm is positioned to contact a charging interface of the electric vehicle. The charging brushes are moved relative to the charging interface such that a portion of the charging brushes is removed as a result of the movement.
