   For example, a real charger profile curved is obtained by sweeping the simulator voltage while recording its voltage and current. The figure to the right shows a typical Lithium ion charging profile curve obtained by using a battery simulator. The profile curve of the charger is obtained in a few minutes. [4]

6. 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.

7. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet. The voltage of the source must be higher than that of the battery to force current to flow into it, but not too much higher or the battery may be damaged.
