  2. Battery pack - Wikipedia

    en.wikipedia.org/wiki/Battery_pack

    Rechargeable battery packs often contain voltage and temperature sensors, which the battery charger uses to detect the end of charging. [4] Interconnects are also found in batteries as they are the part which connects each cell, though batteries are most often only arranged in series strings. When a pack contains groups of cells in parallel ...

    The battery pack also contains a variety of temperature, voltage, and current sensors. Collection of data from the pack sensors and activation of the pack relays are accomplished by the pack's battery monitoring unit (BMU) or BMS. The BMS is also responsible for communications with the vehicle outside the battery pack. [79]

    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.
