48 V – Four Times the Voltage

48 V – Four Times the Voltage

The latest technology making the rounds in the automotive world is a 48-volt system. This quadrupling of the onboard voltage from the earlier 12 volts reduces the current required for a given amount of power by a factor of 4 (P = U x I). A smaller current makes thinner cables possible. Considering the length and number of wires installed in today’s vehicles, the new approach results in a notable reduction in weight and thus fuel consumption. (more…)
