  2. 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]

  3. 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.

  4. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.

  5. Nickel–cadmium battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–cadmium_battery

    Thomas Edison patented a nickel– or cobalt–cadmium battery in 1902, [3] and adapted the battery design when he introduced the nickel–iron battery to the US two years after Jungner had built one. In 1906, Jungner established a factory close to Oskarshamn, Sweden, to produce flooded design Ni–Cd batteries.

    Since it is a current loop, the phone company has a high enough resistance in series with the 48 volt battery to limit the current to a small fraction of an amp. (I have measured around 39 milliamps from a 52 volt phone line). My voltage with the receiver off-hook rises to 79 V DC.

    Here is the test. Three scoring systems are in use, called points, Eliteness, and RC. A bubble like this - (1) gives points, if it says Eliteness or RC, it gives Eliteness or RC.

  8. Electronic waste - Wikipedia

    en.wikipedia.org/wiki/Electronic_waste

    These batteries are one of the most commonly used products in household appliances and other battery powered products in our day-to-day life. The important issue to look into is how this battery waste is collected and recycled properly, which has the consequences of resulting in hazardous materials release into the environment and water resources.

  9. Near-field communication - Wikipedia

    en.wikipedia.org/wiki/Near-field_communication

    In this mode, the target device may draw its operating power from the initiator-provided magnetic field. Active Both initiator and target device communicate by alternately generating their own fields. A device stops transmitting in order to receive data from the other. This mode requires that both devices include power supplies.
