Voltage drop calculationsDC / single phase calculationThe voltage drop V in volts (V) is equal to the wire current I in amps (A) times 2 times one way wire length L in feet (ft) times the wire resistance per 1000 feet R in ohms (Ω/kft) divided by 1000:Vdrop (V) = Iwire (A...
Maximum distance in feet of various guage two conductor copper wire from power source to load for 2% voltage drop in a 12 volt system. Do not exceed the 2% drop for wire between PV modules and batteries. A 4 to 5% loss is acceptable between batteries and lighting circuits in most cases....
Battery voltage, (chart below) can help determine its state of charge. I have researched 12v lead acid battery voltage readings versus percent charge (state of charge) which you may find useful or helpful. I have voltages for 6v, 12v, 24v, and 48v. There are important caveats to this typ...
This calculation was comparatively simple since theta was between 0 and 90 degrees, and therefore, the sine of theta could easily be determined from almost any trigonometric table. Angles Greater Than 90 Degrees Suppose, however, the angle theta at which you want to determine the instantaneous vo...
3.1.2.3.4 Calculation and Measurement of Re The effective internal resistance (Re) of a cell or battery is the relationship between steady-state current and delivered voltage at a specific point in the discharge such as the mid-point (50 per cent of the capacity removed). For example, consi...
For a 103AT-2 type thermistor RTHCOLD = 27.28kΩ and RTHHOT = 3.02kΩ, the calculation results are: RT1 = 5.23kΩ and RT2 = 30.1kΩ. Boost Mode Temperature Monitoring (Battery Discharge) The device is capable to monitor the battery temperature for safety during the Boost mode. The ...
Have a look at my other 48V battery chart here which shows 54.6V as 100%: https://ebikesforum.com/resources/48-volt-13s-battery-voltage-chart-li-ion-batteries.37/ Calculation: 13 Cells x 4.2 Volts/Cell = 54.6 Volts Fully Charged Assumptions: Your pack uses typical 18650 cells which cha...

To make this estimation, the designer predicts the voltage drop from the fire alarm panel to the last notification device. The voltage drop calculation is based on the electrical characteristics of the NAC as it is configured in the specific installation. The designer then subtracts the predicted...
Note that for the boost PWM, even though the input current is continuous, while the output current pulsates, we still base the inductance calculation on the peak-to-peak inductor ripple current. As was previously suggested, the actual selection of the inductor value in a switching regulator is...
