The next simplest mechanism to protect the charger is to install a fuse at the charger output. This fuse must be of adequate current and voltage rating, typically twice the charger’s rated output current and at least twice the charger’s maximum output voltage.
Some protections are required during the charging process, while others make sense only during the discharge process. Thus, some protections are implemented as part of the charger, while others are implemented as part of the battery management system that oversees the charging and discharging process of the battery.
This type of protection for batteries is generally part of the battery management systems. Batteries are electro-chemical products, and hence they are typically sensitive to temperature. In general, heightened temperatures for long times can cause permanent and fatal damage to their cells. This is true for all battery chemistries.
The most common way to protect against this is to include a diode of rated current forward biased towards the positive terminal of the charger, that is, with its cathode pointing towards positive terminal of the charger. The downside of such an arrangement is that during regular current flow, there can be significant power dissipation in the diode.
As batteries can store a huge amount of energy, so sudden discharge or fault can result in catastrophic failures. By handling and maintaining the battery’s functional factors, and protective mechanisms, avert these unsafe operations and prevent dangers such as overcharging, overheating, and short circuits.
