6 FAQs about [How to measure 85 volts with a 60v battery pack]

How do you measure a battery pack voltage?

Battery pack voltage, using a high-voltage resistor divider. Shunt temperature, using a thermistor. Auxiliary measurements, such as the supply voltage, for diagnostic purposes. As demand for batteries to store energy continues to increase, the need for accurate battery pack current, voltage, and temperature measurements becomes even more important.

Can a voltage divider be used to measure a battery pack?

Hello. I want to be able to measure voltage of a battery pack which exceeds 36v. To reduce voltage to the point where it could be measured with an ADC a voltage divider can be used.

What is the shunt range for EV battery pack current measurements?

For EV BMS battery pack current measurements, shunts range anywhere from 25 µΩ to 100 µΩ. One of the most established ways to accomplish highly accurate shunt-based current measurements with a wide dynamic range is to use a high-resolution delta-sigma (ΔΣ) ADC.

How do I measure a single voltage on a PGA?

All you have to do is drop the 36volt with a voltage divider to one of the ranges of the PGA. A convenient one is 4.096volt (PGA gain 1x). Not sure why you need differential mode to measure a single voltage. Note that voltages (any mode) have to fall within supply and ground limits of the chip. Leo..

How many volts should a 36 volt battery be?

Then 36V would become 3.27V, offering a good resolution (almost 80% of full scale; about 26,000 ADC points for 1.4 mV resolution on the battery voltage), and allowing you to measure up to about 44V battery voltage which is important as at full charge your voltage will go well above nominal.

How many volts are in a 5AH battery?

With lead acid and lithium batteries parallel and even series + parallel packs are common. When used in series, the voltage is multiplied but the amp-hours stays the same. So three 5AH 3.6V in series would give a 5AH 10.8V pack. When used in parallel the voltage stays the same and the amp-hours multiply.
