2. 48-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/48-volt_electrical_system

   A 48V 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 without special protective measures.

3. Inductive charging - Wikipedia

   en.wikipedia.org/wiki/Inductive_charging

   The primary coil in the charger induces a current in the secondary coil in the device being charged. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power ...

4. Lithium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Lithium-ion_battery

   A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

5. Jump start (vehicle) - Wikipedia

   en.wikipedia.org/wiki/Jump_start_(vehicle)

   Jump starting a vehicle Crocodile clips, also called automotive clips, on a set of jumper cables. A jump start, also called a boost, is a procedure of starting a motor vehicle (most commonly cars or trucks) that has a discharged battery.

6. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   At this charge rate, Panasonic recommends to terminate charging when the voltage drops 5–10 mV per cell from the peak voltage. [22] Since this method measures the voltage across the battery, a constant-current (rather than a constant-voltage) charging circuit is used.

7. Float voltage - Wikipedia

   en.wikipedia.org/wiki/Float_voltage

   Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]
