Introduction

The SG200 is a battery monitoring system. It's purpose is to provide the user

with continuous information on various parameters of a battery or battery-bank,

and of direct current (DC) usage in the system.

Specifically, it can show:

Parameter

Voltage

State of Charge (SoC)

State of Health (SoH)

Current (A)

Time Remaining

Voltages for two separate Auxiliary

batteries

Who would argue that it is not good to know how much power is left in a

battery? It is like a fuel gauge, and you would not drive a car or boat without

knowing how much fuel is remaining in the tank. Enter the battery monitor. The

most important function of a battery monitor is to report the State of Charge

of a battery or battery bank. The State of Charge (SoC) is a percentage value

showing what percentage of the battery's capacity is remaining.

The SG200 very accurately calculates the State of Charge, and it does so by

incorporating a new feature: State of Health (SoH). State of Health is another

percentage value, that compares the design capacity of a battery, or the

capacity the battery's manufacturer says it should be when new, with it's actual

capacity, which degrades over time as a battery ages.

Accurate and continuous measurement of SoC and SoH is a breakthrough

in battery monitoring. As the battery ages, the monitor does not get less and

less accurate. Instead, the SoC value is always a percentage of the calculated

capacity taking into account the aging and other detrimental effects on a

battery's capacity.

The SG200 also is unaffected by other issues inherent in all other shunt-based

systems, like accuracy drift over multiple partial state of charge cycles. Simply

put, traditional shunt-based products need to reach 100% charge each

cycle. Inaccuracy is introduced that is multiplied with each additional cycle

that does not reach full 100% charge.
