6 FAQs about [How to detect battery voltage temperature and current]

How do battery-voltage and current-monitoring systems work?

In portable electronics designs, typical battery-monitoring systems measure battery voltage and battery current to detect when the battery needs charging or replacement. In this post, I’ll demonstrate battery-voltage and current-monitoring circuitry for cost-optimized systems using operational amplifiers (op amps).

How does a battery temperature sensor work?

A battery temperature sensor allows decisions to be made that adjust the charging voltage based on the battery temperature. As the battery temperature increases, the charge voltage should decrease. Using this sensor as an input to your charging system illustrates this voltage adjustment in the below graph.

How to calculate heating power of a battery?

That, in conjunction with thermal mass and thermal resistance to ambient will let you model the temperature of the battery. Secondly, to estimate the heating power - I^2R - use an estimate of internal resistance and a measurement of the current. The internal resistance can be estimated by comparing the open circuit voltage to the loaded voltage.

How can I measure the temperature of a battery?

To measure the temperature of a battery, you can install a temperature sensor on the negative terminal post. This will give you a graph of the temperature. With the addition of an ambient temperature sensor, the two temperatures can be plotted on the same graph and the difference (∆T) can be shown.

How does a battery temperature monitoring system work?

A battery temperature monitoring system can check and alert if the battery temperature is rising, which can accelerate the reaction rate and cause the battery to accept more charging current, resulting in more gassing. This process continues, and the heat released causes the battery temperature to rise further. The heat released causes the battery temperature to rise, which accelerates the reaction.

How can you monitor battery temperature?

To monitor battery temperature manually, use an IR temperature gun to check the battery string once or twice a week. Record the data in a spreadsheet, ensuring that the temperature difference between the battery and ambient temperature does not exceed more than a 3°C difference. An IR temperature gun can be used for this purpose.
