12v 24v 36v 48v battery fuel gauge battery monitor

HBG1's algorithms is the simple technology in all three ways. It is mornitoring the battery terminal voltage and comparing measured value with build-in fixed voltage-capacity table then give a result of relative remain capacity status. For different chemical battery type, the voltage-capacity curve is different. Further, even for a same battery pack, this curve will be different at higher or lower discharging current. So it is easy to understand why this method only get a gross or rough result. Generally, HBG1 has 10%~20% relative remain capacity tolerance.
