Abstract
The present invention provides an electric braking system and an electric break-away braking system which provide sufficient power, i.e. both current and voltage, to all the electric brakes of a truck or trailer to fully activate them when braking is required. Both braking systems of the present invention utilize two voltage sources which are normally connected in parallel for charging. When braking is required, however, the electronic control circuitry switches the voltage sources from a parallel configuration into a series configuration to provide a sufficient voltage to overcome the resistance losses in the brake lines and thereby provides enough voltage at the electric trailer brakes to have them provide the maximum possible braking.
