Currently, constant current constant voltage (CC/CV) charging protocol is widely used to charge the lithium ion battery, where the batteries are first charged using a preset constant current until the terminal voltage reaches the cutoff voltage and then the terminal voltage is kept as constant while the current proportionately reduces.
Charging the Li-ion battery with constant current and constant voltage (CC-CV) strategy at −10°C can only reach 48.47% of the normal capacity. To improve the poor charging characteristic at low tem...
It denotes a charging curve where the maximum allowed charging current is applied to the battery as long as the cell voltage is below its maximum value, for example, 4.2 Volts. Once the battery reaches that voltage level, the charge controller gradually decreases the current to hold the battery at a constant voltage of 4.2 Volts:
The standard charging protocol for lithium-ion batteries is constant current constant voltage (CCCV) charging. In addition to this, several alternative charging protocols can be found in literature. Section 2 will provide an overview on the different categories of charging protocols and their specific characteristics.
The charging capacity of 1 C is 1.162 Ah, beyond 80% of battery capacity, and the other charging rates only need to recover the rest of capacity at 25°C. While the high charging rate does not work well with temperature decreasing, the charging current rate with the maximum charging capacity of 0.28 Ah is 0.5 C at 0°C.
For practical battery systems, it is most important to select a well-suited cell type. For such cells, a CCCV charging protocol with an appropriate charging current and charging voltage will provide a good overall performance.
Partial Charges: Avoid charging the battery to 100% every time. Studies suggest that maintaining a charge between 20% to 80% can help prolong battery life. Charging to full capacity occasionally is acceptable but not necessary daily. …
