    Lithium ion charger voltage/current profile obtained using a battery simulator. Once the simulated battery voltage is set, the user connects the charger to be tested to the input of the simulator. The charger will detect that a battery has been connected and the charging process will begin.

  9. 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.
