A battery expert once said: "I have not seen a cell balancing circuit that works." For multi-cell packs, he suggested using quality Li-ion cells that have been factory-sorted on capacity and voltage. This works well for Li-ion packs up to 24V; packs above 24V should have balancing. Most balancing is passive; active balancing is complex and ...
CV charging is implemented because the external battery pack voltage seen by the charger IC exceeds the actual battery cell voltage in the pack. This is due to the internal cell resistance, PCB resistance, and the equivalent series resistance (ESR) from the protection FET and cell. To guarantee safe operation, the charger IC must not allow the ...

Estimating SoC by reading the voltage of a charging battery is impractical; measuring the open circuit voltage (OCV) after the battery has rested for a few hours is a better indicator. As with all batteries, temperature affects the OCV, so does the active material of Li-ion. SoC of smartphones, laptops and other devices is estimated by coulomb counting. (See BU-903: How to Measure …

NiMH batteries are ...
The voltage range of hybrid car batteries typically varies depending on the specific make and model but generally falls between 200 and 400 volts. The voltage range of hybrid car batteries is primarily determined by the number of individual cells within the battery pack and the voltage rating of each cell. These cells are often lithium-ion batteries, as they …
So, when the cell voltage is close to 4.2V the charging voltage must be higher e.g. 4.5V, and this should not cause any damage to the cell. Is my understanding correct? I''m asking because the power control module in the battery pack I''m trying to charge seems to cut off the circuit when charging voltage is above 4.5V.

The battery won''t be over-charging, it just gets a higher voltage when charging. However, if an individual module goes higher voltage than it should then it will throw a code, since a weak module will show both a voltage drop and a voltage rise higher than expected.
