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.

A steam turbine used to provide electric power. An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area.
A diagram of an electric power system. The transmission system is in blue. Most North American transmission lines are high-voltage three-phase AC, although single phase AC is sometimes used in railway electrification systems. DC technology is used for greater efficiency over longer distances, typically hundreds of miles.
In a so-called balanced power system, sometimes called "technical power", an isolation transformer with a center tap is used to create a separate supply with conductors at balanced voltages with respect to ground. The purpose of a balanced power system is to minimize the noise coupled into sensitive equipment from the power supply.
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

As realized in the 2007 Volt concept, the initial E-Flex design includes an electric traction motor with peak power and torque outputs of 120 kW (160 hp) and 320 N⋅m (240 lbf⋅ft), a 1 L 3-cylinder gasoline engine coupled to a generator with an output of 53 kW (71 hp), and a 16 kWh (58 MJ) lithium-ion battery energy storage system.
Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers . [ 1 ]
This diagram depicts the electrical structure [22] of the network, rather than its physical geography. Electric power transmission is the bulk movement of electrical energy from a generating site, via a web of interconnected lines, to an electrical substation, from which is connected to the distribution system. This networked system of ...
