What are the characteristics of the small battery during charging and discharging?
A working cycle of the small battery is the charging and discharging process of the charger, so the charging process of the charger is also an important factor affecting the life of the battery. The charging current of the small battery and the charging control method directly affect the life of the battery. The capacity and voltage of the battery pack determine the charging parameters. Therefore, the parameters of the charger should match the parameters of the battery, so as to reduce the chance of damage to the battery due to improper charging.
What are the characteristics of the small battery during charging and discharging? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. You can avoid detours when you use it in the future.
1. Small battery discharge characteristics: If the charged battery is discharged with a constant current, the voltage change of the battery is: the voltage drops to about 1.8V, and the discharge ends. If you continue to discharge, the voltage drops sharply and the discharge stops. The voltage will quickly rise to about 2V. The voltage at point M is called the final voltage of the battery. At this time, the discharge needs to be stopped. So as not to continue discharging so that the electrode plate will be sulfated or reversed to affect the service life of the battery. The voltage drop is related to the discharge rate, the discharge rate is high (that is, high current discharge). The voltage drops fast.
2. Charging characteristics of small battery: When charging with constant current at various hour rates, the voltage-time curve is displayed. The voltage rises when approaching the charging speed, and tends to stabilize. The voltage is maintained at about 2.7 V (10-hour rate), and the charging is completed at this time. The final voltage at the end of charging is related to the charging current. When the charging current is low, the final voltage is also Slightly reduce. The commonly used charging rate is a 10-hour rate, that is, charging takes 10 hours to reach the end of charging.
