What is the standard charging protocol for lithium-ion batteries?

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.

Do charging protocols affect the performance of lithium-ion batteries?

Our experimental cycle life study on charging protocols for lithium-ion batteries has shown that a sophisticated study design is essential for separating the effects of different parameters on the performance of charging protocols.

What is the CCCV protocol for lithium-ion batteries?

As the CCCV protocol is the standard charging protocol for lithium-ion batteries, it serves as a baseline in our study. For all three cell models examined our study, the CCCV protocol is the charging procedure recommended by the manufacturer. Extensive parameter variations were performed for the charging current Ich and the charging voltage Vch.

What temperature should a lithium battery be charged at?

One of the challenges for fast charging is the massive heat generated by high charging currents [ 4 ]. The appropriate operating temperature of the LIB should be within the range of 25–40 °C [ 5, 6 ]. Besides, the temperature difference in a battery module is better to be controlled within 5 °C [ 7].

What is the optimal charging strategy for a battery module?

The results indicate that the optimal charging strategy can achieve a balance between temperature uniformity and charging time at a battery module level. The numerical results of the GA charging strategy, MCC-CV charging strategy and CC-CV charging strategy are listed in Table 2, Table 3 and Table 4, respectively. Table 2.

What is communication protocol?

Communication protocol It defines the communication protocol in detail in <Communication protocol of front-end smart devices>, according to the practical application and characteristic, the protocol (B.12) give a specific definition of the SM and SO(Master Smart Pack). Standard data format is the requirement in the protocol. 2.1.
