Accompanying drawing illustrates:
Fig. 1 is the circuit block diagram of the utility model storage battery charge protection device.
Fig. 2 is the utility model storage battery charge protection device circuit diagram.
Embodiment:
Below in conjunction with drawings and Examples, the utility model is described in further detail:
The each circuit function of the utility model storage battery charge protection device and operation principle:
1, the general structure of storage battery charge protection device circuit is: storage battery charge protection device coordinates with electrical bike charger, and two normally opened contacts in storage battery charge protection device are in series with the 220V electric power loop in charger and the output loop that charges respectively.Charging indicator light circuit in charger is connected with storage battery charge protection device, and the output circuit of charger is also connected with storage battery charge protection device.
2,220V automatic switch-over circuit and the charging effect of output automatic switching circuit and operation principle
This circuit is born primarily of relay K.
When relay does not work (being in release condition), 220V power supply does not access charger input circuit and output wiring terminal.So power plug of charger is inserted on 220V socket for a long time, also there will not be dangerous accident.Insert time more without the need to charging at every turn or pull up after being full of, what decrease 220V attaching plug plugs and unplugs action, improves security performance and the serviceability of battery vehicle charging.
When relay work (being in attracting state), 220V plant-grid connection charger input circuit, makes charger operation; Connected the connection between charger and output wiring terminal, storage battery starts to be charged simultaneously.
3, to charge the effect of automatic starting circuit and operation principle
The effect of charging automatic starting circuit is when charging plug inserts storage battery socket, automatically makes charger enter operating state.Thus eliminate the trouble inserting 220V attaching plug, decrease the chance of artificial contact ac electric device, improve the safe application performance of battery vehicle.
Charging automatic starting circuit is made up of components and parts such as VT1, VT2, R1, R3, C1, VD3.
Under normal conditions, VT1 and VT2 does not work, and relay K is failure to actuate, and contact is open-circuit condition, and charger is also in off position.
When the charging plug of charger inserts battery vehicle, in battery vehicle, the residual voltage of storage battery charges to C1, then by the metering function of resistor R1, makes VT1 obtain suitable operating voltage and conducting.So VT1 drives relay K action, and make relay contact become closure state by normally open, connected 220V current supply circuit, charger is started working.After charger normally works, charging indicator light lights, and gives VT2 indicator light voltage through resistor R3.VT2 obtains suitable base voltage and conducting, makes relay K continue adhesive, produces relay effect with the conducting of VT1.After charger enters work, the rechargeable energy in C1 also can be depleted, makes VT1 enter cut-off state.
After relay contact closure, also connected the connection of charger and charging terminal, storage battery starts to be charged.
4, the effect of charging voltage observation circuit and operation principle
The effect of charging voltage observation circuit carries out, in charging process, constantly detecting battery voltage to storage battery at charger.Battery voltage, once reach setting, at once makes charging automatic starting circuit quit work, at once stops the charging to storage battery.
Charging voltage observation circuit is made up of IC2, R4-R6, C2, C3, VD1, VD2, VT3 and RP.
The reference voltage circuit be made up of VD2, R6 and C3 is connected at the inverting input of IC2; The in-phase input end of IC2 is connected with storage battery; be connected to by R4, RP, C2, VD2 current limliting, dividing potential drop, protecting network simultaneously; by adjustment adjustable resistor RP; can adapt to detect the charging of the various voltage storage batterys such as 24V-60V; and by the pressure stabilization function of VD2, prevent too high voltages from damaging IC2 input.
Charged state, the in-phase input end current potential of IC2 is less than anti-phase input terminal potential, and IC2 exports electronegative potential, VT3 remain off state.When storage battery is full of, when the in-phase input end current potential of IC2 is greater than anti-phase input terminal potential, IC2 exports high potential, and VT3 conducting forces VT2 to become cut-off from conducting, and relay K power-off discharges.So 220V power supply is disconnected, charger exports and also disconnects with charging terminal, reaches the object of protection storage battery, protection charger.
5, the effect of voltage stabilizing circuit and control principle
In order to improve the service behaviour of storage battery charge protection device, devise power circuit, specially for IC2 provides stable working power.
Power circuit is made up of IC1, R7, C4, C5.
The input power of power circuit takes from battery voltage or charger output voltage, delivers to the input of IC1 after R7 step-down, metering function, exports the stable operating voltage of 5V, for IC2 provides stable working power after the voltage stabilizing and C4, C5 filtering of IC1.
6, the structure of storage battery charge protection device
The electronic devices and components of the utility model storage battery charge protection device, are arranged on one piece of circuit board slightly larger than relay.Storage battery charge protection device low-profile, can be placed in various charger easily.
After obtaining the utility model storage battery charge protection device owner agreement, storage battery charge protection device circuit and various charger circuit can be united two into one, form novel battery charger circuit.
The utility model storage battery charge protection device, has: the feature such as practical, safe, reliable, cheap, has positive role, therefore have very large promotion prospect to lifting charger quality and battery vehicle quality.
