A rechargeable battery arrangement for an electric or hybrid vehicle may include a plurality of battery modules and a module connector arrangement electrically contact-connecting adjacent battery modules when in a switching position and electrically separating the adjacent battery modules when in a basic position. The module connector arrangement may include a plurality of module connectors each secured to a respective battery module and including a positive pole contact element and a negative pole contact element. Each respective module connector may be secured to a respective battery module and may include a guide device. The guide device may include an actuating. At least one of a positive pole contact element and a negative pole contact element of a battery module is electrically interconnectable to at least one of the positive pole contact element and the negative pole contact element of an adjacent battery module when the actuating element is actuated.

An information providing system includes: a power-supplying vehicle; a plurality of power-receiving vehicles; and a server. The server is configured to generate a candidate power-supplying target list including information of the plurality of power-receiving requesting vehicles, and notify the candidate power-supplying target list to the power-supplying vehicle so as to make an inquiry to a user of the power-supplying vehicle to select any of the plurality of power-receiving requesting vehicle. The power-supplying vehicle having received this inquiry is configured to present locations of candidate power-supplying targets on a map screen and make a response to the server by notifying, to the server, a power-supplying target selected by the user. The server having received this response matches the power-supplying target notified from the power-supplying vehicle to the power-supplying vehicle, and notifies matching determination information to both the matched vehicles.

A dual drive unit may include two motors, two power transfer mechanisms, and two output shafts. The output shafts are co-linear. The dual drive unit may include two single drive units, which may be similar to each other, coupled together at a joint, which may optionally include a clutch. A drive unit may be modular, and various components may be combined to provide power to an output shaft. For example, a drive unit may include a differential at a first interface, which may be removable, and two drive units may be coupled together at the first interface. A drive unit may have a Z configuration, wherein a motor on a first side of a vehicle powers a wheel on an opposite side of the vehicle.
