Abstract: A battery assembly has a first battery string including a first plurality of cells connected in series. A second battery string is connected in parallel to the first battery string and includes a second plurality of cells connected in series. A fluid channel is operatively connected to the first and the second battery strings and includes a fluid flowing within. A controller is operatively connected to the first and the second battery strings. The controller is configured to determine a desired temperature differential between the first and the second temperatures of the battery strings based at least partially on a respective strength status of the first and the second battery strings. The controller is configured to control the first and the second currents, via the fluid in the fluid channel, based at least partially on the desired temperature differential.

Abstract: A system for fast charging an electric vehicle includes a power plug, a charger, a stationary battery, a DC/DC converter, at least one DC fast charge connector and a control unit. The power plug may be a plug which is operatively configured to engage with a standard 120V power source or a 240V power source. The charger may be a unidirectional charger or a bidirectional charger. The DC fast charge connector is adapted to be removably affixed to an electric vehicle. The control unit is in communication with at least two of the charger, the DC/DC converter, the stationary battery, and the DC fast charge connector to provide fast charge to an electric vehicle.
