ATT - Cabin Heater

One of the most important features of an electric vehicle (EV) is its energy consumption and the resulting range. Especially during cold days, heating becomes very important. Combustion driven vehicles have a lot of waste heat available, which is partly used for heating up the cabin to thermally manage the driver, co-driver and the passengers. In contrast, electric vehicles, don`t produce so much waste heat anymore. Even not close to it. But the requirement for establishing and maintaining thermal comfort is of same importance than for combustion driven vehicles.

ATT - Battery Diagnostic System

The service life of extremely stressed traction batteries depends heavily on whether the cells are operated in the optimal temperature range of 15 °C to 35 °C. If only one cell exhibits problems, this has an impact on the entire module. In addition to effective thermal management, this also requires precise knowledge of the thermal behavior of the cells under all operating conditions. When characterizing the cells, they are subjected to extensive endurance tests with constantly changing loads, during which the cell temperature on the entire surface must also be measured and recorded. The more precise the measurements, the more reliably predictions can be made about the thermal behavior in real operation.
