Abstract
The efficycle, is a hybrid tricycle which runs on manual and electric power. This paper proposes a method to design a braking load to dissipate the excess energy produced when there is no more requirement for the battery to be charged by regenerative braking. This module was designed for an operating voltage of 8V, resistance value of 0.16 ohm and with a maximum current capacity of 200 A. This resistor was coupled with a buck converter to step down the voltage across the battery to a value convenient for operation of the dissipation resistor.
Highlights
Regenerative braking is a technology predominant in almost all the electric vehicles in the market today. This technology helps in recovering the energy wasted as heat during friction braking. This in turn helps in recharging the batteries and using this free energy to run the vehicle whenever required. [1] presents an energy recovery system with feedback to the distribution grid based on a new converter topology
Every regenerative brake should have a mechanism to channel this excess energy by converting it to some other form
To further exploit the potential of brake energy regeneration, brake resistors can be introduced into regenerative braking system of electrified vehicles
Summary
Regenerative braking is a technology predominant in almost all the electric vehicles in the market today This technology helps in recovering the energy wasted as heat during friction braking. [2,3] discusses the design methodology and the technology used to manufacture a solar Electric Vehicle that can be commercialized for the benefit of the society. One such mechanism is the inclusion of a heat dissipating resistor to direct the excess energy to the environment in the form of heat energy These resistors are like heating coils used in stoves which can withstand very high temperatures without getting damaged. A new type of regenerative braking system with a brake resistor applied is proposed and researched in [10]. A new simplified methodology has been proposed in [15] to extract the power from the wheels into the battery by operating the Induction Motor in the generating mode even while the brakes are applied
