Battery with a system

Turning electricity into mobility. What might sound simple at first is actually complex. This is why we have created a clear and comprehensible presentation of the battery system in the modular electric drive matrix (MEB). After all, you should know what’s in your ID.

‌

Simply explained: the ID. Family battery system

The ID. Family’s newly developed modular electric drive matrix (MEB) has been specifically designed for electric vehicles. The heart of the system is a fast-charging battery system consisting of different numbers of battery modules, depending on the desired range. Each of these modules contains 12 lithium-ion battery cells. The cells utilised in the MEB have a “pouch cell” design. They consist of multiple stacked or folded active layers enclosed by a flexible outer film. This makes pouch cells highly flexible in terms of their shape and optimally adaptable to the specific requirements. In addition, their smooth surface also provides high heat dissipation.

Simply electrifying: the lithium-ion battery

A lithium-ion battery cell always consists of four components: Anode, cathode, separator and electrolyte. This cell is also called a galvanic cell. During charging, electrons migrate from one electrode to the other and are stored there. The electrical energy from the power grid is converted into chemical energy in the process.

During the discharging process - to operate the vehicle's electric motor, for example - the process takes place in reverse order: The electrons now travel from the electrode where they are stored back to the other electrode. In the process, the chemical energy is converted back into electrical energy.
