What is E-axle (Electric Drive Unit)?

It saves space and weight. It is used on many EVs. Units can be replaced as a whole. Integration reduces cables, weight and assembly cost and makes the unit easy to fit to different models. Many suppliers offer complete e-axle units. Cooling is usually shared between the motor and inverter through the vehicle's coolant circuit.

How it works

The motor drives the wheels through a reduction gear.

Why it matters for your car
