In an electric vehicle, Mercedes-Benz places particular emphasis on protecting the high-voltage system. All related components, such as the high-voltage battery, drive motors, high-voltage electrical cables, and connected components, exceed legal requirements and meet the stringent Mercedes-Benz standards.
In the new electric GLC, the battery housing is integrated into the crash concept as part of the vehicle structure. Furthermore, with the new generation of high-voltage batteries, Mercedes-Benz has implemented comprehensive measures to prevent potential thermal reactions, including appropriate spacing between the battery cells and the design of the cells and cell modules. The enhanced early warning system includes not only alerting the occupants but also other vehicle-side safety measures – for example, the automatic closing of side windows and ventilation flaps. A new sensor, centrally located in the high-voltage battery, now monitors the modules even when the vehicle is switched off.
Mercedes-Benz has also implemented its high-voltage safety concept in the GLC to ensure that, after an accident, electrical components pose no danger to occupants, first responders, or rescue personnel. This safety concept has already proven successful in other all-electric Mercedes-Benz models – confirmed by the findings of Mercedes-Benz accident research. This includes, for example, the automatic shutdown of the high-voltage system in the event of a serious accident. A distinction is made between a reversible and an irreversible shutdown.
