Some systems may take it a step further with more sophisticated SOC algorithms, but all are based on measuring current flowing in and out of the battery bank. The battery monitor should now show a SOC of 95%. After one hour 5Ah is added back to your remaining capacity. Now let’s put a 5 Amp charge back in your battery. If you draw 10 Amps from your battery for one hour (10Ah), the SOC should read 90% (or 90Ah) remaining. Charge current coming back in from a battery charger or solar is ADDED to the available battery capacity.ĮXAMPLE: A 100Ah battery charged to 100% has a 100Ah of available capacity. Here’s how it works at a very basic level.Įlectrical current (Amps) leaving the battery to power your gear is subtracted from the available battery capacity. The control unit takes the current measurements over time and converts them into Amp Hours.įinally, the computed Amp Hours are either added to or subtracted from the available battery capacity. Those measurements are sent in real-time back to the control unit. The shunt measures electrical current as it flows back and forth across it. Here’s an article explaining Amp Hours if you’re not sure what that means. So the battery monitor first needs to know how many Amp Hours of energy your battery bank can store when it’s fully charged. How Battery Monitors Calculate the State-Of-Chargeĭeep cycle batteries are rated in Amp Hours (Ah).

It measures all energy flowing in and out of the battery and passes that data back to the control/display unit. With most battery monitors, the shunt is a separate device connected between the battery and the rest of the system.
