BMW 3: Introduction
The "charging" procedure for an electric vehicle corresponds to "refuelling" a conventionally driven vehicle. Accordingly, in this chapter "charging" means:
- Charging the high-voltage battery unit during operation.
- Charging procedure via a charging cable.
As a charging cable is used, one also refers to conductive (grid-bound) charging.
Components inside and outside the vehicle are required for charging. In the vehicle a charging socket and power electronics are required for the voltage conversion. Outside of the motor vehicle, additional components are required; these are referred to as the "Electric Vehicle Supply Equipment (EVSE)" in the standards and in development. Details on the possible versions, structure and functioning of the EVSE are described in the chapter "Electric Vehicle Supply Equipment".
The voltage of the AC voltage network can be in the range of 100 V to 240 V. It is supplied to the G20 PHEV as a single phase.
For the employees in BMW Service the following important safety rules must be observed in relation to charging:
No work may be carried out at the vehicle during charging mode. The charging cable must be disconnected from the vehicle before starting work.
During the charging procedure the electric coolant pumps and the electric fan can be switched on automatically for cooling the high-voltage components.
The current repair instructions "Safety information for handling hybrid vehicles" must be observed for this purpose.

Overview of charging options
The high-voltage battery unit of the G20 PHEV can generally only be charged
by alternating current
(AC charging) at a maximum charging power of 3.7 kW. The charging option for the
high-vol

Shift elements
Brakes and clutches are described as shift elements which make possible the
shifting and changing
of all gears. Like in the GA8HP70Z transmission, the following shift elements
are also used in the
GA8P75HZ transmission:
2 fixed multidisc brakes (brakes A and B)
3 rotary multidisc clutches (clut
Automatic climate control - adjusting the air flow manually
Concept
The air flow for climate control can be adjusted
manually.
General information
To adjust the air flow manually switch off AUTO
program first.
Operation
Press the lower or upper side of
the
button: decrease or increase air flow.
The selected air flow is shown on the climate
control display.
