Systems and methods for storing energy for use by an electric vehicle are disclosed. Systems can include an electric vehicle battery pack including a rack configured to couple a plurality of independently removable battery strings to the vehicle, the battery strings configured to be selectively coupled in parallel to a vehicle power bus. The battery strings may include a housing, a plurality of electrochemical cells disposed within the housing, a circuit for electrically connecting the electrochemical cells, a positive high-voltage connector, a negative high-voltage connector, a switch within the housing, and a string control unit configured to control the switch. Each battery string can include a coolant inlet and a coolant outlet configured to couple with and sealingly uncouple from an external coolant supply conduit and an external coolant return conduit, and an auxiliary connector configured to couple with an external communications system and/or an external low-voltage power supply.

The present invention pertains to a supporting structure for receiving battery cells in a battery system of a hybrid or electrical vehicle, the supporting structure comprising a bottom plate and two side plates arranged on the bottom plate, wherein the inner sides of the two side plates and the bottom plate define an internal volume for receiving the battery cells and wherein each side plate comprises a flange at its outer side and wherein each flange comprises fixation means for fastening the supporting structure to an adjacent supporting structure.

A terminal block includes a casing, a terminal portion and an SD switch. The casing is provided to an electrical device. The terminal portion is provided on the casing and has a terminal cover that is fitted to a base for accommodating terminals. The SD switch is provided to the casing, and has a female connector and a lever portion that is fitted to the female connector to mechanical connect and disconnect from the electrical device. The lever portion constitutes an interlocking portion that restricts a disengaging operation of the terminal cover, when the lever portion is fitted to the female connector.

A portable power system assembly that includes a portable power system (PPS) and a dock. The dock is mountable to a vehicle and includes a PPS holding tray and an actuator arm, with the actuator arm capable of being pivoted from a first position to a second position, the holding tray including a PPS receiving station and a PPS securing station, and the securing station including electrical supply terminals. The PPS includes a housing with opposing ends, there being mating electrical terminals at one end and at least one abutment region at the other end for engagement with the actuator arm. The actuator arm engages with the abutment region of a PPS in the receiving station to move, during pivoting of the actuator arm from its first position to its second position, the PPS from the receiving station to the securing station for mating electrical engagement of the PPS and dock electrical terminals, and, in its second position, the actuator arm engages with the PPS in the securing station to releasably lock the PPS in the securing station.
