The block diagram shows how the hardware are connected to each other and what kind of connection that will be using. As shown above, We will be using two battery of 12V, 17Ah in series. However, since 17Ah of battery can be used for about half hour. Therefore, the team decided to use two other battery of 12V and 7Ah in series and with parallel to the two 12V, 17Ah battery. The connection between Motor Controller and Motor will be done by the use of PWM (Pulse Width Modulation).
