   AC charger with boost feature Jump starter with lithium battery Some AC battery chargers have a boost , engine start , or engine assist feature. Despite being able to assist in jump starting a dead vehicle battery, these types of battery chargers perform their task over a longer period of time, rather than an instantaneous boost.

3. Automobile auxiliary power outlet - Wikipedia

   The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts during engine start due to the high temporary battery current usage.

4. 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 and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

5. Wi-Charge - Wikipedia

   The system consists of a transmitter and a receiver. Transmitter connects to a standard power outlet and converts electricity into infrared laser beam. Receivers use a miniature photo-voltaic cell to convert transmitted light into electrical power. Receivers can be embedded into a device or connected into an existing charging port.

6. Inductive charging - Wikipedia

   en.wikipedia.org/wiki/Inductive_charging

   The first standard for vehicle wireless charging was the SAE J2954 standard. It allows inductive car charging over a pad, with power delivery up to 11 kW. [22] As of 2024, standards for higher-power wireless charging and for charging while driving are being developed. [23]

7. Electric car charging methods - Wikipedia

   en.wikipedia.org/wiki/Electric_car_charging_methods

   Constant voltage charging is a widely used charging method involving constant voltage between the battery poles. The starter battery uses constant voltage charging when the vehicle is running. If the specified voltage constant value is appropriate, it can ensure that the battery is fully charged, while also minimizing gas and water loss.
