Battery pack has 0 voltage

How to properly read battery cells voltage from a battery pack?

I have a battery pack that has 16 cells, maximum voltage is 67.2V. I need to read out the voltage of each cell with a high precision, preferably 1 mV using a built-in 12 bit ADC of STM32F103. I think that to get high precision I need to measure each cell separately rather than measure the cell voltage referenced to the battery pack ground.

6 FAQs about [Battery pack has 0 voltage]

Can a 12V battery pack take a charge?

A 12v Battery Pack was at 0V and wouldn't take a charge. Manufacturer Miady recommended starting up the sleeping BMS with a 9-volt battery across the terminals. I tried this -- it worked! Battery read just over 10V on voltmeter. Immediately connected to charger.

How to recover a lithium-ion battery pack from 0V?

If there are undervoltage cells, open the battery caps and fill each compartment with water to optimum levels or electrically add a desulfation device. When it comes to recovering a lithium-ion battery pack from 0V, the first thing to check is if the BMS BMS has tripped or failed.

Why is my Li-ion battery 0V?

On another note, if you measure 0V from a li-ion, it might just be that its protection circuit has disconnected it from the terminals to prevent a deep discharge. Depending on how that protection circuit is designed, you can recover the battery by simply charging it. Or the protection circuit might act like a fuse and never reconnect the terminals.

Why does a lithium-ion battery show 0V on the output?

In some cases, a lithium-ion battery may show 0V on the output even though the cells are not really at 0V. This can happen when the BMS is either tripped or has failed. In these situations, reviving a lithium-ion battery from 0V is possible because the cells are not really at 0V.

Can You recover a lithium ion battery from zero volts?

Recovering a Lithium-Ion battery cell from zero volts is not recommended, as it can result in a fire. This is because once the cell goes under about 2.5 or 2.6 volts, a chemical reaction occurs inside the cell that permanently damages it and drastically increases its internal resistance.

Can a PSU charge a battery up to 2V?

If you want to charge the batteries up to 2V, maybe set the voltage to 2V then so it stops the current once it reaches those 2V. Be wary though: if the battery voltage recovers on its own to higher than the set voltage, the PSU will be forced to sink current, which most don't support.
