2. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A smart battery requires a smart charger. Some smart chargers can also charge "dumb" batteries, which lack any internal electronics. The output current of a smart charger depends upon the battery's state. An intelligent charger may monitor the battery's voltage, temperature or charge time to determine the optimum charge current or terminate ...

3. Power management system - Wikipedia

   en.wikipedia.org/wiki/Power_Management_System

   Its task is to make sure that the electrical system is safe and efficient. If the power consumption is larger than the power production capacity, load shedding is used to avoid blackout. Other features could be to automatic start and stop consumers (e.g., diesel generators ) as the load varies.

4. Voltage regulator - Wikipedia

   en.wikipedia.org/wiki/Voltage_regulator

   Early automobile generators and alternators had a mechanical voltage regulator using one, two, or three relays and various resistors to stabilize the generator's output at slightly more than 6.7 or 13.4 V to maintain the battery as independently of the engine's rpm or the varying load on the vehicle's electrical system as possible.

5. Automatic generation control - Wikipedia

   en.wikipedia.org/wiki/Automatic_generation_control

   An electrical grid may have many types of generators and loads; generators must be controlled to maintain stable operation of the system. In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power ...

6. Uninterruptible power supply - Wikipedia

   en.wikipedia.org/wiki/Uninterruptible_power_supply

   A UPS differs from a traditional auxiliary/emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions by switching to energy stored in battery packs, supercapacitors or flywheels. The on-battery run-times of most UPSs are relatively short (only a few minutes) but sufficient ...

7. Automobile auxiliary power outlet - Wikipedia

   en.wikipedia.org/wiki/Automobile_auxiliary_power...

   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.
