Basic principle of battery over-discharge protection

 Basic principle of battery over-discharge protection

The following takes lead-acid battery as an example to introduce the over-discharge protection principle of the controller. 1. Discharge characteristics of lead-acid batteries The discharge characteristics of lead-acid batteries are shown in Figure 1. It can be seen from the discharge curve that the battery discharge process has three stages. In the beginning (OE) stage, […]

Photovoltaic power generation system controller

Photovoltaic power generation system controller

In the independent operation of photovoltaic power generation system and solar street light, energy storage battery must be equipped. The battery plays the role of storing and regulating electric energy. When there is excess electric energy generated by sufficient sunshine or strong wind, the battery stores the excess electric energy; on the contrary, when the
