The Bogart Trimetric battery monitor uses current and voltage readings to track the power in and out of a battery. A precision resistive shunt is installed between the negative terminal of the battery and all the loads. All current going into the battery (charging) and all current leaving the battery (discharging) is measured. Electronic circuitry and a microcontroller record battery voltage and battery current. Because the Trimetric keeps track of current leaving or entering the battery, a very good approximation of the state of charge of the battery can be determined and displayed.
