Switching-Mode Battery Test System

The constant current charging circuit (charger) and constant current discharge circuit (electronic load) of the traditional battery testing system (programmable type) use the analog linear constant current source circuit as the main structure. As a result, its efficiency is poor and electric energy cannot be recycled (the constant current discharge test of battery). Thus, it causes thermal pollution and requires cooling equipment to ensure that the system is working properly, and is energy-consuming. The constant current charging circuit (charger) and constant current discharge circuit (electronic load) of the switching-mode battery testing system (programmable type) use the PWM constant current source circuit architecture. Its efficiency is good and wasted electric power can be recycled (the constant current discharge test of battery). Therefore, it can save energy and reduce carbon emissions. According to the experimental data, its overall energy savings can reach 25%.
