Battery voltage, twelve point two.
It even shows your car battery voltage.
To get an accurate battery voltage reading, the PV panel is disconnected just before the battery voltage reading is taken and then reconnected immediately after if the battery voltage is below 13V.
The battery voltage (Fig. 4d, orange curve) rises to 2.5 V in about 6 min.
To estimate the energy density, the Ccell value must be multiplied by the average battery voltage, E = CcellV.
The Roswell research found, generally, that when battery voltage increased to 4.8 volts from 3.2 volts, toxin levels increased markedly.
The ADC interrupt automatically switches between the two channels for the photodiode and the battery voltage, reading the battery voltage once for every five times the photodiode is read.
Battery voltage that drops below 5.9 volts is insufficient and indicates the battery needs to be replaced.
The system takes a reading from the ADC, input from either the photodiode or the battery voltage, once per second.
A regulator ensures that the output voltage is properly matched to the battery voltage as engine speed varies.
Look for the last recorded battery voltage which will be at the bottom of the Excel sheet.
