6 FAQs about [How to measure batteries in series]
How to measure a battery cell based on a circuit diagram?
It is possible to measure individual battery cells. According to the circuit diagram, the GND signal of the upper module should not be connected to the Aurdino. First, measure the voltage of the lower battery cell based on 720mV (720mV > 3.6V).
How do you measure voltage across a battery?
The technique is to measure the voltage across high potential battery first, than against the lower ones and negating the subsequent batteries voltage from the one at higher potential. For example for the above circuit the measured voltage across battery-1 is 48v and battery-2 is 36v. Negating 48v-36v=12v gives us battery-1 voltage.
Can we measure battery voltage in parallel?
In parallel combination voltage across each battery remains same. So we can not measure individual battery voltage in this case. These are some of the ways through which batteries connected in series or parallel can be monitored. If you have any more method in your mind please let me know about it.
How to calculate battery pack voltage?
You could also use 6 voltage dividers, one for the first battery, another for the first two batteries in series, another for the first three batteries in series, etc. Then, using software you can just subtract adjacent readings to get individual battery pack voltages. We had a whole big thread on this not too long ago.
How do you calculate the voltage of a battery cell?
First, measure the voltage of the lower battery cell based on 720mV (720mV > 3.6V). The value calculated in this way (3.6V) must be subtracted from the second measured value (4.34-3.6= 740mV). Calculate the voltage of the second battery cell based on 740mV (740mV > 3.7V). This only works in a narrow range of battery voltages.
How to monitor an industrial battery?
First, you need to minimize the drain on the battery form your monitoring solution. Optocouplers are not good for this. Second, there are many more equally important things that need monitoring, like temperature, for example. Industrial battery monitoring solutions measure all that, estimate each cell impedance, life time etc.
