Batteries in the substations have two typical states: one is the check-discharge state, in which the batteries are discharged for 8 h at 0.1 C (Capacity) to determine whether the battery pack has certain reliability. The other is the floating charge state, in which the batteries are connected to the charger to maintain full power.

The most common type of substation battery charger is the 110V charger, which produces a voltage of 110 volts. This type of charger is typically used to charge lead-acid batteries, such as those used in car batteries. Some other types of substation battery chargers include the 220V charger and the 12V charger. Substation Battery Maintenance
Li-ion battery packs are not sensitive to temperatures in the range of 0-40℃, however, once the temperature exceeds this range, the life and capacity will be reduced. The low-temperature performance of lithium-ion batteries is also different for different materials. Temperature range of ternary lithium-ion battery pack

The ideal temperature range for a lithium-ion battery is between 32°F and 113°F (0°C and 45°C). If the temperature gets too high, it can cause the battery to overheat and potentially catch fire. If the temperature gets too low, it can cause the battery to freeze and become damaged. So what should you do if your phone gets too hot or too cold?
Substations are prevalent in all petrochemical facilities. Their function is to distribute power to the process units. Typically, there are either one or two types of battery systems within each substation. There may be a "station power" battery system to power the switchgear controls, which typically operates at 125VDC.
As an example, I''ll use an electric utility substation battery to establish a test specification. The battery consists of a 200 ampere-hour (AH) system with 60 cells.
