Portable multifunctional storage battery detection system

The invention discloses a portable multifunctional storage battery detection system. An AC/DC conversion plate is connected in parallel with input ends of a 360V/12V conversion plate, a 360V/24V conversion plate and an auxiliary power panel through a capacitor plate. An output end of a master control plate is connected with a control end G pole of a MOSFET (Metal-Oxide -Semiconductor Field Effect Transistor) via a super capacitor charge control signal and is connected with a buzzer through a keyboard plate. A negative pole of a battery access is connected with a D pole of the MOSFET. An S pole connection line of the MOSFET passes through a discharge current transformer and is connected with an input end of a battery discharging port (a negative pole). The portable multifunctional storage battery detection system provided by the invention is high in versatility and integrates multiple functions; and the detection and maintenance of a battery can be effectively completed with one piece of equipment, so that the overall cost of storage battery maintenance is greatly reduced.
