A CC-CV charging method is a hybrid approach that controls either output current or output voltage at a time. While charging the battery, at first it uses CC charging, and when the battery''s voltage hits up to the required threshold value, the charging step shifts from CC charging to the CV charging method as shown in Fig. 3 (b) [19], [20].
As with most things in engineering, arbitrarily increasing the pack voltage isn''t unequivocally a good thing, and that''s even without invoking a reductio ad absurdum argument (e.g. if 1 kV is better than 100 V, then 10 kV is better than 1 kV, etc.). Still, there are some benefits to increasing the pack voltage, and the most obvious is that less cross
In addition, parasitic oxidation is also accompanied by the generation of gases (mainly CO 2, CO, O 2, H 2, CH 4, etc.) that adhered to the electrode surface, leading to problems such as obstruction of lithium-ion migration and increased internal pressure of the battery.Studies have shown that the higher the voltage is, the stronger the parasitic
