Li-ion Battery and Gauge Introduction | Richtek Technology

The coulomb counter operation theory is to connect a sense resistor in the charge/discharge path of battery. The ADC measures the voltage on the sense resistor and then transfers the current value when battery is under charge or discharge. A real time counter (RTC) provides the timing base for integrating the current to coulomb information.

6 FAQs about [Lithium battery coulomb counter]

How accurate is a Coulomb counter for batteries state of charge?

For applications using batteries, the situation is often critical if users are suddenly without energy (for example electric bicycles, security cameras, alarms, IoT, on-board sensors). In these cases, the accuracy of a Coulomb Counter for batteries State of Charge measurement is a “must have”.

How does a Coulomb counter work?

To correct this marginal, the Coulomb counter is automatically re-calibrated to each charge cycle. By coulomb counting SoC measurements allow a less than 1% measurement error, which allows a very accurate indication of the remaining energy in the battery.

What is a cc75 CC150 cc500 Coulomb counter?

CC75, CC150, CC500 Coulomb Counters from MyLithiumBattery.com allow the user to obtain a state of charge in % (SoC – State Of Charge), and a precise depth of discharge (DoD) of the battery. They also calculate, in real time, the time remaining before the battery is completely empty.

How does a coulomb meter work?

The coulomb meter high precision allows the monitoring of the voltage (V), the capacity (Ah), the power (W) and the energy a battery. This information allows the user to get a State of charge in % (SoC) or a depth of discharge (DoD) says the battery. It calculates in real time the remaining time until the battery is completely empty.

What is the difference between GCO and coulomb counting?

Unlike the method GCO, coulomb counting is independent of fluctuations in power delivered by the battery (that cause the battery voltage drops), and the accuracy remains constant regardless of the use of the battery. Counter high-precision coulomb designed to monitor the voltage, capacity, power and energy of a battery.

Why is a Coulomb counter re-calibrated to each charge cycle?

Although the current is measured by a precision resistance, low errors of measures involved, related to the frequency of sampling of the measure. To correct this marginal, the Coulomb counter is automatically re-calibrated to each charge cycle.
