Process for improving the charging and discharging capacity of storage batteries
TLDR
In this paper, a process for improving the charging and discharging capacity of storage batteries at low temperatures is described, which is accomplished by raising their temperature, using for this purpose the energy stored in the batteries.Abstract:
The invention pertains to a process for improving the charging and discharging capacity of storage batteries at low temperatures. The improvement in the charging and discharging of storage batteries is accomplished by raising their temperature, using for this purpose the energy stored in the batteries. The process is conducted in such a way that the temperature and at least one value characterizing the state of charge are measured before the beginning of the heating and during the heating and the storage battery is discharged through an electrical component introducing thermal energy into it, at which time the discharge is terminated when either the target loadability in the discharging or charging was achieved or the state of charge decreases below a threshold value.read more
