Voltage drop calculation formula

Jul , 19 2024

Voltage drop is a common issue in circuits. To calculate the decrease in voltage, we can use the following formula: Vout=Virn * (R2/(R1+R2)). This formula is based on the principle of resistance voltage division, where Vin represents the input voltage, Vout represents the output voltage, R1 represents the resistance value of the upper resistor, and R2 represents the resistance value of the lower r...

Lithium battery life The reason for the slow charging speed

Dec , 13 2024

1. Electrical problems: Insufficient power of the charger is one of the common reasons for slow charging speed. If the output current of the charger used is small and cannot meet the maximum charging current requirements of the battery, the charging speed will be limited. For example, a lithium battery mobile phone that supports fast charging, the original charger output current is 3A, and the cha...

How to maintain the consistency of lithium batteries

Apr , 19 2025

1. Balance control of the Battery Management System (BMS) Passive equalization: Through resistor discharge, the energy of high-charge cells is dissipated in the form of heat, making the voltages of each cell tend to be consistent. It is suitable for cost-sensitive scenarios, but the efficiency is relatively low. Active balancing: It transfers the energy of high-charge cells to low-charge cells thr...
