Abstract
A contactless battery system includes a sealable case, a battery unit disposed within the sealable case, and at least one wireless power transmission coupler connected to the battery unit and disposed within the sealable case. The battery unit includes an arrangement of serially connected battery cells in a fixed number of banks of battery cells to deliver a set voltage and current. The wireless power transmission coupler is disposed with respect to at least one face of the sealable case to enable magnetic inductive signaling for charging, discharging, and communication with the battery unit. A battery management controller communicates bidirectionally with the contactless battery systems and with electrically powered equipment to control charging. A distribution system manages distribution of the contactless battery systems to a plurality of depots adapted to store, charge, or exchange depleted contactless battery systems under control of at least one management unit.
