The experimental system consists of lithium power battery special test equipment, computer, lithium iron phosphate power monomer battery, as shown in Fig. 4.3. The graph of ohm resistance and SOC in charge–discharge model Specific experimental scheme is as follows:
Detection methods include determining when the current drops to 0.1 C during the constant-voltage stage and, in more basic chargers, charging for only a predetermined time and assuming the battery is fully charged. Many chargers also include facilities to determine the battery temperature, so that charging can cease if a threshold is exceeded.
