Higher Voltage Systems

As electrical energy demands increase on cars, other higher voltage systems are needed. Nickel Metal Hydride (NiMH), Lithium-ion (Li-ion), and Lithium-ion polymer (Li-poly) batteries are used in hybrid and electric vehicles. Higher voltage systems can be identified by their orange cables. Warning: Be extra careful around high voltage systems. High voltage can kill. For safety, high voltage system integrity is monitored by sensors and the computer. If there is a malfunction, problem, or an airbag deploys the high voltage supply cuts off.
