Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model is elaborated.
The structural representation of utility model as shown in Figure 1, a kind of vehicle-mounted charge and emergency power supply system based on electric automobile, comprise electrokinetic cell and charge circuit, emergency signal trigger module, socket current detection module, battery electric quantity acquisition module, discharge loop and first～four relay that this system also comprises control unit and is attached thereto respectively, control unit also connects charge circuit; Electrokinetic cell is connected with the input of discharge loop through the 3rd relay, and the output of discharge loop is connected with electric automobile socket through the first relay; Electric automobile socket is connected with the input of charge circuit through the second relay, and the output of charge circuit is connected with electrokinetic cell through the 4th relay; Control unit detects the triggering signal of emergency signal trigger module, and gathering the electric quantity signal of electrokinetic cell and the current signal of electric automobile socket by socket current detection module and battery electric quantity acquisition module respectively, control unit is controlled the operating state of the first～four actuating of relay and charge circuit and discharge loop according to the signal collecting.In the present embodiment, control unit has also connected display, for showing the dump energy of electrokinetic cell.
Operation principle of the present utility model is: under normality, the first～four relay is all in off-state.Emergent trigger module is provided with trigger switch, in the time that user needs electrokinetic cell to power to external equipment, presses trigger switch, emergent trigger module sends lasting triggering signal to control unit, control unit detects the dump energy of electrokinetic cell and the current signal of electric automobile socket, only send triggering signal at emergent trigger module, the dump energy of electrokinetic cell is higher than discharge threshold, when the charging socket of electric automobile meets without civil power simultaneously, control unit is just controlled the first relay and the 3rd relay adhesive, and enable discharge loop and outwards discharge, system enters discharge mode, in this process, the dump energy of control system cycle detection electrokinetic cell, in the time that the dump energy of electrokinetic cell is equal to or less than the discharge threshold of setting, control system stops the electric discharge of discharge loop, disconnect the first relay and the second relay, system exits discharge mode.
The dump energy that emergency signal trigger module Triggerless, electrokinetic cell detected when control unit has city's signal of telecommunication lower than charge threshold and the electric automobile socket set, control unit control the second relay and the 4th relay closes, and control unit enables charge circuit, system enters charge mode, and it is power battery charging that electric automobile socket is got civil power.In this process, the dump energy of control system cycle detection electrokinetic cell, the electric weight that control unit detects electrokinetic cell greater than or equal to set charge threshold time, control unit control the second relay and the 4th relay disconnect, system exits charge mode.
Above embodiment is only explanation technological thought of the present utility model; can not limit protection range of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection range.
