The Concerns of the people in front of burning cars are great. This applies to vehicles with petrol or diesel tank, but also for the maybe that’s why rare species with gas-powered engines. And frightening images, with the ends in the flame of Tesla’s rising drives the concern also-and especially-in electric car, especially as the same is clear of the fire particularly difficult, and is suspected to ignite sometimes without the external shock itself. The manufacturer take constructive action, but one hundred percent security does not exist.

Us a reader sends a photo of an Audi A8, of the 4. June in a car dealership in Mülheim an der Ruhr was burned to the ground. Without external influence, while he was standing in the exhibition hall, unmoving. The suspicion is that a part of the hybrid system has ignited, because Audi gives since a few weeks the customers of its mild hybrid vehicles to avoid the statement with on the way, only Outdoor Parking, and garages or underground garages. There is also a call back by the force travel Federal office (KBA), the subject however, so far, only the models A4, A5, A6, A7 and Q5 model years 2017 to 2020. Are recognized in the world of 610,000 vehicles in Germany 83.250. According to the KBA may “due to moisture, start the generator occurs in the Belt, in consequence of the short-circuit bridges are formed, which can lead to a local Overheating in the component. A subsequent vehicle fire, the following can not be ruled out“. Be affected only vehicles with 2.0 TFSI and TDI engine and Mild Hybrid System.
The belt starter generator (RSG) with integrated power electronics provides said to Valeo. The starter generator is used instead of a conventional pinion starter is used and is connected via a belt connected to the crankshaft of the internal combustion engine. It provides for better utilization of performance, a smooth automatic Start-stop at the red light and reduces fuel consumption by up to 0.7 litres per 100 kilometres. Electrically, you can travel, however, scarcely any, or only a few kilometers. The technique uses due to their relatively large benefits to a relatively low price on all manufacturers and model series in order, often associated with the note “for 48-Volt on-Board network” or “48-Volt electrification”. The associated power electronics is protected by a water cooling system from Overheating.
