Technical information

BMW i - the safety of the eDrive is an essential element of all BMW i
vehicles
The safety of the eDrive is an essential element of product development. A variety of measures safeguard operating
safety, including in the event of accidents.

Fully insulated high-voltage system.

Automatic safety cutout (disconnection) of the high-voltage battery in the event of an accident with airbag
activation.

Permanent monitoring of the high-voltage cables and other safety-relevant criteria, as well as automatic safety
processes.
All systems have demonstrated their safety in crash tests and standard checks. The BMW system tests have
demonstrated system safety at a level that exceeds the statutory requirements.
What does "high-voltage system" mean in the vehicle?
In vehicles with high-voltage systems, components are installed that are operated with voltages above 60 V direct current
voltage or 25 V AC voltage. Some components in these vehicles need high electrical powers. The high-voltage electrical
system in hybrid cars and electric vehicles operates with direct current voltages of up to 650 V and has to provide large
amounts of electrical energy.
Which components make up a hybrid car?
In addition to the drive unit, a hybrid car is made up from the following fundamental components:

High-voltage battery

High-voltage cables

Electrical machine electronics
