2. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect current sensor; the only difference is that this method uses the saturable inductor instead of the Hall-effect sensor in the air gap. Saturable inductor current sensor is based on the detection of an inductance change. The saturable inductor is ...

3. Battery pack - Wikipedia

   en.wikipedia.org/wiki/Battery_pack

   A portable power bank charging a mobile phone. A power bank is a portable device consisting of a battery, a charger to interface battery with charging power source and an output interface to provide desired output voltage. [10] Power banks are made in various sizes and typically based on lithium-ion batteries. A power bank contains battery ...

4. 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.

5. Battery balancing - Wikipedia

   en.wikipedia.org/wiki/Battery_balancing

   Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. [1] A battery balancer or regulator is an electrical device in a battery pack that performs battery balancing. [ 2 ]

6. Battery indicator - Wikipedia

   en.wikipedia.org/wiki/Battery_indicator

   In battery types where EMF remains approximately constant during discharge, but resistance increases, voltage across battery terminals is not a good indicator of capacity. A meter such as an equivalent series resistance meter ( ESR meter ) normally used for measuring the ESR of electrolytic capacitors can be used to evaluate internal resistance ...

7. Battery tester - Wikipedia

   en.wikipedia.org/wiki/Battery_tester

   Battery tester. A battery tester is an electronic device intended for testing the state of an electric battery, going from a simple device for testing the charge actually present in the cells and/or its voltage output, to a more comprehensive testing of the battery's condition, namely its capacity for accumulating charge and any possible flaws affecting the battery's performance and security.

8. Current clamp - Wikipedia

   en.wikipedia.org/wiki/Current_clamp

   Resembling a current clamp in appearance and function is the Rogowski coil current sensor. This coreless transformer is used in clamp meters and power monitoring loggers. It has the advantage of better linearity, having no core to saturate, it can be made flexible, and does not require any magnetic or electrical contact at the opening end. [2]

9. List of battery types - Wikipedia

   en.wikipedia.org/wiki/List_of_battery_types

   This list is a summary of notable electric battery types composed of one or more electrochemical cells. Three lists are provided in the table. Three lists are provided in the table. The primary (non-rechargeable) and secondary (rechargeable) cell lists are lists of battery chemistry.
