  2. Resistance thermometer - Wikipedia

    en.wikipedia.org/wiki/Resistance_thermometer

    The voltage drop due to the lead resistance has been cancelled out. This always applies if R1=R2, and R1, R2 >> RTD, R3. R1 and R2 can serve the use of limiting the current through the RTD, for example for a Pt100, limiting to 1 mA, and 5 V, would suggest a limiting resistance of approximately R1 = R2 = 5/0.001 = 5,000 Ohms.

  3. 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]

  4. Battery pack - Wikipedia

    en.wikipedia.org/wiki/Battery_pack

    Lead-acid automobile battery pack consisting of 28 Optima Yellow Tops Lithium-ion battery pack for Lucid Motors. A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. [1] [2] They may be configured in a series, parallel or a mixture of both to deliver the desired voltage and current. The term ...

  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 battery regulator is an electrical device in a battery pack that performs battery balancing. [ 2 ]

  6. State of charge - Wikipedia

    en.wikipedia.org/wiki/State_of_charge

    In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready. [5]

  7. Thermistor - Wikipedia

    en.wikipedia.org/wiki/Thermistor

    Thermistors are also commonly used in modern digital thermostats and to monitor the temperature of battery packs while charging. Thermistors are often used in the hot ends of 3D printers ; they monitor the heat produced and allow the printer's control circuitry to keep a constant temperature for melting the plastic filament.

  8. Callendar–Van Dusen equation - Wikipedia

    en.wikipedia.org/wiki/Callendar–Van_Dusen_equation

    The Callendar–Van Dusen equation is an equation that describes the relationship between resistance (R) and temperature (T) of platinum resistance thermometers (RTD). As commonly used for commercial applications of RTD thermometers, the relationship between resistance and temperature is given by the following equations.

    Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
