A vehicle body for an electrically driven vehicle, having a vehicle frame for transmitting mechanical forces during the operation of the vehicle. The vehicle frame has a battery portion for receiving at least two battery modules, and the battery portion has at least one fastening interface for fastening the at least two battery modules in the received position.

This objective is achieved according to the present invention in that in a method for determining the deterioration of a battery, the charge and discharge cycles of the battery are measured by number and depth of the charge/discharge. For each of the charge and discharge cycles, a characteristic deterioration value is determined on the basis of a deterioration curve that is characteristic of the specific battery type. These individual characteristic deterioration values are then summed up to obtain the deterioration of the battery.

Method for determining the deterioration of a battery

A vehicle having a transmission for transmitting a torque from a drive machine to drive wheels, with the transmission having an transmission output shaft and a transmission input shaft, in which the torque can be transmitted from the drive machine to the transmission output shaft, and having an electrical machine which has a rotor and a stator, which means being provided in order to connect the electric-motor torque of the electrical machine optionally to the transmission input shaft or to the transmission output shaft.

Vehicle transmission with selectively-engageable electric motor

A heat exchanger structure for a plurality of electrochemical storage cells has at least one duct component through which thermal control medium flows. The duct component has two material strips which are arranged parallel to one another and between which a heat exchanger duct is formed. The material strips have shaped portions adapted to the storage cells. The heat exchanger structure is useable, for example, for a motor vehicle battery.

An electric drive unit includes an electronic control and monitoring module integrally connected to an electric motor. The housing of the electric motor has a double-walled construction to form a water jacket with cooling water passages therein. The electronic module includes at least one high power component that requires cooling. This component is mounted directly on a cooling insert that extends through a recess in the electronic module housing and is inserted in an opening provided in the outer wall of the motor housing. In this manner, the cooling insert is integrated into the water jacket of the motor housing and is directly cooled by the cooling water flowing in the cooling passages. A very compact and reliable construction is achieved, in which the electric motor and the electronic module share a common water cooling circuit. External water hoses and external electrical connections between the electric motor and the electronic module are avoided.
