Electrical caddy for postal distribution energy flow analysis

The idea of this prototype begins with the necessity of transporting heavy loads. The idea was to create a caddy capable of delivering safe and easy charges in urban areas. The project emerged to help the postal service and provide them a reliable solution. The problem to transport these payloads over the city is indeed difficult for the postal workers. A caddy equipped with several compartments would be suitable to solve this problem. However, the key point was the difficulties to drive a normal caddy with heavy payloads. Implementing electric motor on the caddy could be a solution to carry these payloads. The German company “Expresso” (with experience about this kind of electric caddy) created an electric caddy following the specifications of the postal companies. This kind of caddy is using in this moment by the German postal service. The Belgium and British postal service are going to use this caddy also in a future. Solutions available in this moment cannot be comparable with the efficient propose we have mentioned, an electrical caddy which in addition, is more ecological. This leads to the NEPH project for the creation of an electric caddy. Our first aim is to obtain the differences in consumption on different types of undergrounds and payloads. Nevertheless, the main aim of the project will be to obtain a simulation model to estimate the energy consumption of the caddy. Introducing several parameters: • Weight. • Number of stops. • Height difference. • Different types of Undergrounds. The comparison between the real consumption and the estimation will give us a prediction of the real consumption of the caddy depending on different situations. To be successful with our simulation model, it must be as realistic as possible.
