Lithium battery charging-undervoltage

Using only CV, especially with a low-resistance charger output/cables/etc, may cause an excessive current to flow when battery''s own voltage is much lower than the CV limit. This in turn may exceed battery''s advised/safe charging current, may cause the battery to heat up, and cause all sorts of futher problems.

Understanding Lithium Ion Battery Current Variation During Charging

Lithium Ion Battery Current Variation During Charging And Discharging is crucial in understanding the behavior of these batteries. During the charging process, the current gradually decreases as the battery reaches its capacity. Conversely, during discharge, the current increases as the battery provides energy to the device.
