Solar Street Lamp Charging And Discharging Monitoring System

As we all know, the LED street light project is the representative project of the current energy saving and emission reduction project. On the illuminating components, the characteristics of the LED itself have achieved very good energy-saving effects. With years of attention to the power supply, we have made great efforts to improve the quality and efficiency of the power supply. LED power products currently have conversion efficiencies of over 90%, and some products are as high as 95%, meeting the high efficiency requirements of all applications.
The conditioning circuit is used to sample the output current of the photovoltaic cell, the discharge current of the battery, and the charging and discharging working voltage of the battery at a certain frequency, and the collected data is sent to the computer by the USB data acquisition module. The battery output signal is a floating signal. The use of differential measurement in LED streetlights minimizes the impact on the circuit under test and also reduces measurement errors.
