BMW 3: Introduction
The electrical machine in the G20 PHEV is a permanently excited synchronous machine. It can convert electrical energy from the high-voltage battery unit into kinetic energy, by which the vehicle is driven.
Both electric driving up to approximately 87 mph (140 km/h) as well as support of the combustion engine are possible, for example when overtaking (boost function) or for active torque support when changing gears.
In the reverse situation, the electrical machine converts kinetic energy into electrical energy during braking and in coasting (overrun) mode and stores this in the high-voltage battery unit (energy recovery).
The electrical machine is a high-voltage component
High-voltage component warning sticker
Each high-voltage component has on its housing an identifying label that enables Service employees and vehicle users to identify intuitively the possible hazards that can result from the high electric voltages used.
Only Service employees who satisfy all the prerequisites are permitted to work on the designated high-voltage components: suitable qualifications, compliance with the safety rules, procedure following the exact repair instructions.
For high-voltage safety reasons, with the exception of the high-voltage battery unit no other high- voltage component must be opened.

Parked-car ventilation
Concept
The car's interior can be cooled or heated before
driving off with the parked-car ventilation. Depending
on set temperature and ambient temperature,
the car's interior is ventilated or possibly
heated using the residual engine heat.
General information
The system can be switched on and off d
Wireless charging tray
Concept
The wireless charging tray enables the following
functions to be performed without cables:
Charging the rechargeable battery of a mobile
phone with Qi capability and of other mobile
devices, which support the Qi standard.
Charge the BMW Display key, see Owner's
Manual for the vehicle.
