How to control the discharge depth of lead-acid battery?

To control the discharge depth of lead-acid batteries, the following measures can be taken:

The control system shall be set with reasonable discharge protection voltage and discharge cut-off voltage. 

Monitor the battery status, timely detect the voltage, current, temperature and other parameters of the battery, and control the charging and discharging of the battery based on the monitoring results, while avoiding excessive discharge and ensuring the charging status of the battery.

Based on the usage and actual needs of the battery, develop appropriate discharge strategies, such as using segmented discharge control to divide the total capacity of the battery into several equal parts, and discharge them sequentially during operation to avoid single discharge depth exceeding the battery's tolerance range.

For lead-acid batteries, special charging methods such as "three-stage" charging or pulse charging can also be used to extend the battery life. When charging, try to avoid excessive charging current as much as possible to avoid causing damage to the battery.

It should be noted that in order to ensure the safety and reliability of the photovoltaic power generation system, in addition to using control strategies to control the depth of battery discharge, it is also necessary to regularly inspect and maintain photovoltaic components, batteries, and other equipment, as well as check whether the system wiring and parameter settings are correct to avoid equipment damage or safety accidents.
