Abstract

Some types of electric cars use 48V battery. The Rinus C1, the one we developed, uses six eight‐volt‐battery units connected in series. As this battery’s voltage level is higher than the level needed by electrical / electronic devices in the car, a DC/DC converter or a voltage adapter is therefore required. In our case 12V voltage supply is required by the car lightings, electromagnetic door openers, a tablet PC and a multi‐purpose USB charger. We have previously developed an efficient 48V/12V switched‐mode DC/DC converter however an issue has been recognized: the complexity of on‐board cabling of our circuit (although not so complex) rose the risk of module malfunction due to unintended cable displacement by a technician during the eCar assembly and maintenance. Having studied the case, we come to an idea that a simple voltage adapter may fit the need better. For this aim a general‐purpose power‐diode is predicted to be a good choice for the voltage dropping task considering its current capacity suitability to our client’s requirement and its wide availability in the market. The current‐voltage characteristics of a power diode (6A05G) is studied. Based on the data obtained, a simple voltage adapter module is successfully developed using a series of diodes as voltage droppers. The module is now used in the car. In addition to that, the module simplicity implies easier, faster and cheaper development. Keywords Voltage adapter, DC/DC converter, electric car, Mohammad Nasucha
