The battery of an electric vehicle transforms chemical energy into electrical energy when the vehicle is powered and reverses the process when it recharges.
In each element, 2 electrodes of different materials are separated by an electrolyte, a solid or liquid substance that allows the passage of electrical current.
Electrons carrying electric charges (ions) from the electrodes migrate from one to the other, creating an electric current.
More environmentally friendly, the main challenge of this technology is to develop its autonomy, which is the interest of the EcoGreen Energy Challenge.
Competitors will have the option to use one or two batteries to power the accessories and propulsion system.
The results will be calculated from the amount of energy measured in Joule in a validated attempt using a calibrated joule meter, provided by the organization.
