What is the regenerative braking system?
Electric car and electric vehicle regenerative braking system, we explain how it works and what are the benefits of this technological innovation.
Alke' Electric Vehicles with regenerative braking system
We explain how it was possible this innovation
There are different type of electric motors, Alkè electric vehicles use a special last generation motor with separate excitation, with a power of 6-11kW and peak of 17.5kW (24kW for the XT 320E). This electric motor during normal operation receives electricity from batteries. During braking operation the same motor works as a dynamo and generates energy that, instead of being wasted in heat from brakes, is sent to the drive batteries. This makes possible for the electric vehicle to get lower average consumption and consequently higher autonomy. Different studies have been made by universities to understand which is the real benefit of this innovation and it is estimated that you can get a saving of about 30%. This value is reached especially in work situations of stop and go type, typical of maintenace works.
To explain better how the regenerative braking works we make a practical example:
Comparison between waste collection with electric vehicles with regenerative braking system and diesel/petrol vehicles
If we use a petrol or diesel vehicle for waste collection we have a series of waste:
If we use an electric vehicle with regenerative braking system:
In such situations you can then reach a saving of about 30% with the regenerative braking system increasing in proportion the batteries autonomy.
