　　Equalizing charging method for button battery cr1620 pack protection board

　　Commonly used button battery cr1620 pack balancing charging technologies include constant shunt resistance balancing charging, on-off shunt resistor balancing charging, average battery voltage balancing charging, switched capacitor balancing charging, buck converter balancing charging, inductor balancing charging, etc. When a set of lithium batteries is charged in series, each battery should be charged evenly, otherwise the performance and life of the entire set of batteries will be affected during use.

　　1. Attach a parallel balancing circuit to each single cell of the button battery cr1620 pack to achieve a shunt function. In this mode, when a battery reaches full charge first, the balancing device can prevent it from overcharging and convert the excess energy into heat energy to continue charging the under-charged battery. This method is simple, but it will cause energy loss and is not suitable for fast charging systems.

　　2. Before charging, discharge each cell one by one through the same load to the same level, and then perform constant current charging to ensure a more accurate equilibrium state between each cell. However, for battery packs, due to physical differences between individuals, it is difficult for each cell to achieve completely consistent ideal effects after deep discharge. Even if the same effect is achieved after discharging, new imbalances will appear during the charging process.

　　3. Timing, sequencing, and individually detecting and evenly charging the single cells in the button battery cr1620 pack. When charging the button battery cr1620 pack, it can be ensured that each button battery cr1620 in the battery pack will not be overcharged or overdischarged, thus ensuring that each battery in the button battery cr1620 pack is in normal working condition.

　　4. Using the time-sharing principle, through the control and switching of switch components, additional current flows into the battery with a relatively low voltage to achieve the purpose of balanced charging. This method is more efficient, but the control is more complicated.
