　　1. The reasonable battery is measured to 10-20%of the battery capacity. For soft short circuits, this is equivalent to 3-6 months of discharge rates per month; for uneven cycle time, this is equivalent to 16%capacity loss at 100 cycles.

　　2. The reasonable time required for battery equalization can be short to only one charging/discharge cycle. SOC unevenness takes a longer time, up to 18 hours (these 18 hours are not entirely used for charging, but a process of adjustment and discharge adjustment process at least one charging/discharge cycle). Unbalanced capacity usually requires 1 hour, and at least 2.5 hours.

　　3.18650 has the highest capacity, 2,000mAh, and usually uses up to 3 battery parallel. Therefore, the maximum equilibrium current required to modify 20%of the capacity is iBARANCE = (20%× 2000mAh × 3)/1.0HR=1200ma In order to achieve the equilibrium of this level, the adjustment of the battery pack must be adjusted for a long time. Assuming that the charging time is 1 hour and the discharge time is 3 hours, the two -hour balance can be obtained after two charging/discharge cycles. This requires a balanced current to be 150mA.High. For example, if the battery is 4V, the power consumption can reach 0.6W when the balanced power supply is 150mA. The best compromise is to control the battery equilibrium current between 50mA-150mA, and the initial equilibrium will continue multiple cycles.
