2. 48-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/48-volt_electrical_system

   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.

   en.wikipedia.org/wiki/Automotive_battery

   A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

   Nissan Leaf cutaway showing part of the battery in 2009. An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.

5. 42-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/42-volt_electrical_system

   This limit eliminates the option of an automotive electrical system with a nominal battery voltage of 48 V, because at low temperatures the charging voltage of the battery can attain 60 V. Also, the price, weight and volume of batteries are influenced by the number of cells, which must therefore be kept to a minimum. New battery technologies ...

6. Electric vehicle conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_vehicle_conversion

   Prices gradually declined to approximately US$350 per kW·h by mid-2009. As the LiFePO 4 cells feature life ratings of 3,000 cycles, compared to typical lead acid battery ratings of 300 cycles, the life expectancy of LiFePO 4 cells is around 10 years. LiFePO 4 cells require more expensive battery management and charging systems than lead acid ...

7. Ignition interlock device - Wikipedia

   en.wikipedia.org/wiki/Ignition_interlock_device

   The standard device in the US consists of a mouthpiece mounted on a handheld unit and a cord that attaches to the vehicle’s ignition system and runs on the battery. The driver is required to blow into the mouthpiece to test his or her alcohol level before starting the car. [ 24 ]
