More Information
Summary:The utility model discloses a 200V(voltage) accumulator units discharging capacity testing device adopting the scheme which can make direct current output of the discharge of the accumulator invert to the alternating current, and can revert synchronously the alternating current to the alternating current net. The capacity testing device comprises a discharging circuit which is composed of a DC/DC isolation converter (3), a DC/AC current source inverter (4), an electric filter (5), and a control loop which is composed of a control processor (9), a monitor (10), a current mutual-inductor (1) and a main electric appliance (6). The utility model is safe and accurate, avoids the defects of the traditional measuring approach.
