Abstract: Regenerative braking systems provide an efficient method to assist series hybrid ambulance microbus better fuel economy while lowering exhaust emissions. This paper describes design of hardware core for a regenerative braking system implemented on an extended range series hybrid ambulance microbus (Zhang et al., 2008). Results indicate that a professional to standard wiring concept were applied to connect the components together to make a complete series hybrid model in a way to have full manual control of power flow over the entire driveline. The significant amount of energy that is expended to get a vehicle moving at a certain speed is currently converted into heat by the friction brakes in the process of stopping that vehicle. Regenerative braking technologies are ones that are able to store some of this kinetic energy into usable forms of potential energy and then release it in a fashion that will help get the vehicle moving again.
