Upon entering the second stage, the battery SOC should be about 50 %. This approach, as previously discussed, helps mitigate battery expansion strain and capacity loss. In this stage, the charging current is reduced according to the real-time strain. The strain is controlled by the charging current and maintained at the strain limit boundary.
