A method of continuously charging the battery with a small current. Its name derives from the trickle of water. Although the charging time is longer, the advantage is that the battery is not affected even if a small current continues to flow in a fully charged state.
The acceptable charge current is high at the low side of battery SOC and declines with augmented SOC, based on polarization properties . The maximum charge current is determined by battery kinetics limits. The temperature rise also needs to be considered to extend battery lifetime when designing charging patterns.
Smaller charge current is then employed at the end of charging to decrease battery polarizations and to procure more charge capacities. Meanwhile, the temperature rise is calculated as a constraint, preventing thermal runaway and ensuring charge safety.
This paper + presented the design of a constant-current/constant-voltage charging control strategy for a battery cell using the so-called cascade control system arrangement with the adaptation of the battery charging current based on the open-circuit voltage (OCV) parameter estimation.
First, taking the acceptable charge current as the optimal charge current limit, the battery is charged with high current at the initial charging stage to speed up the charging process.
