Abstract
A connection system is provided to charge a high voltage battery () in an electric vehicle with multiple low voltage solar panels (). The connection system includes sets of transmission lines () to individually connect each one of the solar panels () to each individual one of the battery cells () making up the battery (). With the connection system the high voltage battery () can be charged by the lower voltage solar panels () without using a lossy DC-DC converter system that converts the DC solar panel output to AC for transforming to the much higher voltage across the primary terminals of battery () before converting back to DC to connect to the battery ().
