Design of a Battery Electric Town-Car

The purpose of this research is to contribute to the design and build of a battery electric town-car, which must be safe and road legal and capable of carrying two adults and a modest quantity of luggage and/or shopping. There are many decisions to be made, from things such as batteries and motors, to smaller things such as windscreen wipers and seat-belt positioning. This will incorporate a wide and varied range of engineering. It might be an issue due to the size and the amount of the batteries and if we are shortening the chassis this poses another problem. But we are certain all the batteries and components will fit. For that reason, we are going to test using CAD (computer aided design). For this design project a budget of 6000 has been set by the client for a small production run. With the entire customer requirements to consider it was decided that the Li-ion batteries best suit the power requirements and the weight/space limitations of this car. With these dimensions the controller will fit into the designated space. Based on the output figures we know this controller is capable of a top output of at least 40KW and a sustained output of at least 18KW. This is enough to meet the power requirements needed to start the car, accelerate at the required speed and drive it around at speeds up to 60mph.
