9.2 SOC Change Description
1. How does the SOC change from 99% to 100% when the battery is about to be
fully charged?
When the SOC is greater than 99%, the battery switches to float charging and the
charging current decreases gradually. Finally, the SOC reaches 100%.
2. When the battery temperature is low, the charging power is displayed as about
300 W, but the SOC does not change. Why?
When the internal temperature of the battery module is low, the internal heating
component starts to heat the battery. The heating power is 300 W (typical value).
When the heating component is working, the battery is not charged and the SOC
does not change. Battery heating helps to keep the cell at a proper operating
temperature and prolong the service life of the product.
