  2. Electric vehicle battery - Wikipedia

    en.wikipedia.org/wiki/Electric_vehicle_battery

    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. Compared to liquid fuels, most current battery technologies have much lower ...

  3. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_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. Once the engine is running, power for the car ...

  4. Lithium iron phosphate battery - Wikipedia

    en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

    Lithium iron phosphate modules, each 700 Ah, 3.25 V. Two modules are wired in parallel to create a single 3.25 V 1400 Ah battery pack with a capacity of 4.55 kWh. Cell voltage Minimum discharge voltage = 2.0-2.8 V [26] [27] [28] Working voltage = 3.0 ~ 3.3 V; Maximum charge voltage = 3.60-3.65 V [29] [27] Volumetric energy density = 220 Wh/L ...

  5. Sodium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Sodium-ion_battery

    Their pouch cells have energy densities comparable to commercial Li-ion batteries (160 Wh/kg at cell-level), with good rate performance up to 3C, and cycle lives of 300 (100% depth of discharge) to over 1,000 cycles (80% depth of discharge). Its battery packs have demonstrated use for e-bike and e-scooter applications. [35]

  6. State of charge - Wikipedia

    en.wikipedia.org/wiki/State_of_charge

    In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready. [5]

  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]

  8. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    A battery charger, recharger, or simply charger, [ 1][ 2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged. Some battery types have high ...

  9. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    At low temperatures, a battery cannot deliver as much power. As such, in cold climates, some car owners install battery warmers, which are small electric heating pads that keep the car battery warm. A battery's capacity is the amount of electric charge it can deliver at the rated voltage. The more electrode material contained in the cell the ...
