The CitiCar came in three models. All three models had a flat diagonal front, a flat roof, and a flat nearly vertical back. Early coupes, designated as model SV-36, had a 2.5 hp (1.9 kW) motor and 36V battery pack. The second model coupes, designated as model SV-48, had a 3.5 hp (2.6 kW) motor and 48V battery pack, and some small improvements.
A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures.

The first electric golf cart was custom-made in 1932, but did not gain widespread acceptance. [3] In the 1930s until the 1950s the most widespread use of golf carts was for those with disabilities who could not walk far.

A shunt charge controller or shunt regulator diverts excess electricity to an auxiliary or "shunt" load, such as an electric water heater, when batteries are full. [ 7 ] Simple charge controllers stop charging a battery when they exceed a set high voltage level, and re-enable charging when battery voltage drops back below that level.
The SAE discussed an increased automobile standard voltage as early as 1988. [3]In 1994, at the initiative of Daimler-Benz, the first "Workshop on Advanced Architectures for Automotive Electrical Distribution Systems" was held at the Massachusetts Institute of Technology Laboratory for Electromagnetic and Electronic Systems (MIT/LEES) in Cambridge, Massachusetts USA. with the aim of defining ...
