2. Charge controller - Wikipedia

   en.wikipedia.org/wiki/Charge_controller

   Charge controllers are sold to consumers as separate devices, often in conjunction with solar or wind power generators, for uses such as RV, boat, and off-the-grid home battery storage systems. [1] In solar applications, charge controllers may also be called solar regulators or solar charge controllers.

3. Conductive charging - Wikipedia

   en.wikipedia.org/wiki/Conductive_charging

   Conductive power transfer uses electrical contacts to connect a power supply to a portable device in order to transfer energy. The technology is sometimes called "conductive wireless charging". [ 1 ] The need for a conductor-to-conductor connection between the power supply and the device is the main difference from inductive charging and other ...

4. Backup battery - Wikipedia

   Additionally these batteries power the remote cellular phone systems that thwart phone line snipping as well. The backup battery usually has a lifespan of 3-10 years depending on the make and model, and so if the battery runs flat, there is only one main source of power to the whole system which is the mains power.

5. Comparison of commercial battery types - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_commercial...

   Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion. As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here. [64]

6. Uninterruptible power supply - Wikipedia

   en.wikipedia.org/wiki/Uninterruptible_power_supply

   The difference between the two voltages is because charging a battery requires a delta voltage (up to 13–14 V for charging a 12 V battery). Furthermore, it is easier to do the switching on the line-voltage side of the transformer because of the lower currents on that side.

7. Qi (standard) - Wikipedia

   en.wikipedia.org/wiki/Qi_(standard)

   A Qi system consists of two types of devices – the Base Station, which is connected to a power source and provides inductive power, and Mobile Devices, which consume inductive power. The Base Station contains a power transmitter that comprises a transmitting coil that generates an oscillating magnetic field ; the Mobile Device contains a ...

9. Lithium iron phosphate battery - Wikipedia

   en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

   This busbar is rated for 700 amps DC to accommodate the high currents generated in this 48 volt DC system. Lithium iron phosphate modules, each 700 Ah, 3.25 V. Two modules are wired in parallel to create a single 3.25 V 1400 Ah battery pack with a capacity of 4.55 kWh. Cell voltage Minimum discharge voltage = 2.0-2.8 V [27] [28] [29]
