If the housing of the high-voltage battery has been damaged, electrolyte and gases may leak out.
In the event of a vehicle fire, the internal pressure of the high-voltage battery could exceed a critical value. In this case, flammable gas escapes through a bleed valve in the vehicle's underbody.
The gas can ignite.
The hybrid system combines a combustion engine with an electric motor.
the combustion engine is generally switched off.
engine idling only occurs in certain instances.
if the high-voltage battery is sufficiently charged, the vehicle can be started with the electric drive without the combustion engine (noiseless start).
if the high-voltage battery is not sufficiently charged or the operating temperature of the combustion engine has not been reached, the vehicle can start with the combustion engine.
the combustion engine is switched off as often as possible during the journey.
the vehicle can be accelerated electrically up to speeds of approximately 140 km/h.
the electric motor supports the combustion engine (boost effect), e.g. when pulling away or accelerating.
the high-voltage battery is discharging.
the electric motor is operated as a alternator when in overrun mode and during braking.
the high-voltage battery is charging.
vehicles with hybrid systems generate significantly less noise than vehicles with combustion engines.
when driving in electric mode the vehicle may not be heard by other road users due to the significantly less noise generated. Adapt your driving style accordingly.
