What causes a battery to over-discharge?

The over-discharge can occur in a variety of situations, such in cells without BMS in various aerospace and implantable medical devices. In active implantable medical devices (AIMDs), the battery in a patient’ s body can reach an over-discharge state due to patient negligence or disease.

What happens if you overcharge a battery?

As a result, the voltage in the cell rises – this is known as over-charging. On the one hand, this is harmful to the battery and bad for its life span. On the other hand, it can pose a safety risk for the user. The excess energy leads to heat generation. “In the worst case, this can lead to a so-called ‘thermal runaway’.

What happens if a battery is deeply discharged?

“If a battery does become deeply discharged, special care must be taken during the subsequent recharge. With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke.

What happens if you don't charge a battery?

If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell. As a result, the voltage in the cell rises – this is known as over-charging. On the one hand, this is harmful to the battery and bad for its life span. On the other hand, it can pose a safety risk for the user.

What happens if a battery is discharged to 0 volt?

When a battery is discharged to 0 V and stored at 0 V, the anode still retained a certain amount of reversible lithium inventory, and the potential rose slowly and was lower than the dissolution potential of Cu (Fig. 9 d–f). The RLE remained nearly 100% capacity retention rate (CRR) after three 3-day zero-volt storage. Fig. 9.

Can a lithium battery be overcharged?

In order to operate lithium-batteries safely and optimize their life span, they should not be over-charged or deep discharged. What happens when a battery is over-charged? If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell.
