Charging nimh batteries with solar panel
WebThe charge algorithm for NiMH is similar to NiCd with the exception that NiMH is more complex. Negative Delta V to detect full charge is faint, especially when charging at less than 0.5C. A mismatched or hot pack reduces the symptoms further. NDV in a NiMH charger should respond to a voltage drop of 5mV per cell or less. WebFor NiMH cells, the maximum charging voltage is 1.6 V and the maximum current rate is 0.05 C for up to 20 hours. For a three pack, that would be 4.8 V (3 × 1.6 V) and 125 mA (2500 mAh × 0.05 C = 125 mA). I’m not worried about maximum number of charging hours, because sunlight isn’t going to exceed 20 hours in Chicago.

C/20 means the rated amp hour capacity divided by 20. So a 2000 mah battery would be charge at a constant current of 100 milli-amps for 20 hours. Ok enough of the bad news.
WebMay 10, 2015 · In addition, you will need to add a 110 Ω resistor between the output of the solar cells and the Zener. The value is calculated by dividing the voltage drop 16.5 V - 12 V by the full-load current of 40 mA. At no load, the Zener will dissipate 0.04 A * 12 V = 500 mW, or half the maximum rating (1 W) of the diode. Share. WebJul 9, 2015 · Build a solar panel nimh charger.
