Set-up of the MEB lithium-ion battery

The MEB batteries are built as follows: the
bottom layer provides solid buffer protection.
Introduction
Placed on top is the aluminium battery housing
with a crash frame, integrated battery cooling
and a connection box for the high-voltage and
low-voltage electrical system (AC, DC and 12

V).
The newly developed MEB cell modules, which
consist of individual battery cells, are installed
New Business
in the battery housing. The cell controllers
(CMCe) – control units to monitor the cells
(voltage, currents and temperature) and cell
balancing (ensuring the cells are uniformly
New Standards
used in day-to-day operation) – are integrated
in the longitudinal beam of the battery housing.
