Abstract
The application relates to the circuit design field, especially to a battery simulator circuit. The battery simulator circuit comprises a linear voltage stabilizing circuit and a voltage clamping circuit. A voltage stabilizing output end of the linear voltage stabilizing circuit is connected to a clamping end of the voltage clamping circuit. The voltage stabilizing point of the linear voltage stabilizing circuit is smaller than a clamping point of the voltage clamping circuit. The voltage stabilizing output end of the linear voltage stabilizing circuit is connected to the clamping end of the voltage clamping circuit, so when the voltage stabilizing point of the linear voltage stabilizing circuit is set to be smaller than the clamping point of the voltage clamping circuit, the circuit can simulate a battery. When the circuit simulates discharging of the battery, a power source is connected to the input end of the linear voltage stabilizing circuit; when the circuit simulates charging of the battery, the power source is connected to the clamping end of the voltage clamping circuit.

As shown in Figure 1, the battery analogue circuit that the application provides, comprises linear voltage-stabilizing circuit 1 and voltage clamping circuit 2; The output end of pressure-stabilizing of linear voltage-stabilizing circuit 1 is connected with the clamp end of voltage clamping circuit 2, and the voltage stabilizing point of linear voltage-stabilizing circuit 1 is less than the clamped point of voltage clamping circuit 2.
Linear voltage-stabilizing circuit 1 comprises: resistance R1, resistance R2, adjustable resistance R3, NPN triode Q1, reference voltage source U1; The clamp end of voltage clamping circuit 2 is connected with the emitter of NPN triode Q1; One end of resistance R1 is connected with the input end of linear voltage-stabilizing circuit 1, and the other end is connected with the negative electrode of reference voltage source U1 and the base stage of NPN triode Q1; The base stage of NPN triode Q1 is connected with the negative electrode of reference voltage source U1, and collector is connected with the input end of linear voltage-stabilizing circuit 1, and emitter is connected with one end of resistance R2;
The reference pole of reference voltage source U1 is connected with the other end of one end of adjustable resistance R3 and resistance R2, the adjustable side of adjustable resistance R3 and the plus earth of reference voltage source U1; Voltage clamping circuit 2 comprises: resistance R4, resistance R5, adjustable resistance R6, PNP triode Q2, reference voltage source U2; One end of the output end of pressure-stabilizing of linear voltage-stabilizing circuit 1 and the clamp end of voltage clamping circuit 2 and the emitter of PNP triode Q2, one end of resistance R4 and resistance R5 is connected; The negative electrode of the base stage of PNP triode Q2, the other end of resistance R4, reference voltage source U2 is interconnected; The reference pole of the other end of resistance R5, one end of adjustable resistance R6 and reference voltage source U2 is interconnected; The adjustable side ground connection of the collector of PNP triode Q2, the anode of reference voltage source U2 and adjustable resistance R6.
According to Fig. 1, VCC is the input end of linear voltage-stabilizing circuit 1, and VOUT is the output end of pressure-stabilizing of linear voltage-stabilizing circuit 1, simultaneously also as the clamp end of voltage clamping circuit 2.
The principle of work of this battery analogue circuit simulated battery is as follows:
Consumer 3 is connected between VOUT and ground.By regulating the resistance of adjustable resistance R3, the voltage that the reference of adjustable reference voltage source U1 is extremely gone up, thus the output end of pressure-stabilizing voltage V1 of linear adjustment mu balanced circuit 1.By regulating the resistance of adjustable resistance R6, the voltage that the reference of adjustable reference voltage source U2 is extremely gone up, thus the clamp terminal voltage V2 of regulation voltage clamp circuit 2.Make V1 be less than V2 by regulating adjustable resistance R3 and adjustable resistance R6 and get final product simulated battery.
When power supply is accessed by VCC, get final product the discharge mode of simulated battery.Because V1 is less than V2, voltage clamping circuit 2 cannot enter clamping state, and therefore, the voltage stabilization of VOUT, at V1, realizes the simulation to battery discharge status.
When power supply is inputted by VOUT constant current, get final product the charge mode of simulated battery.Owing to being provided with the clamper terminal voltage V2 of voltage clamping circuit 2, therefore the voltage of VOUT can raise until reach set clamper terminal voltage V2 gradually, voltage clamping circuit 2 enters clamp state, and the voltage stabilization of VOUT, at V2, realizes the simulation to battery charging state.
In actual use, V2 only need be set and be a bit larger tham the charge and discharge mode that V1 gets final product simulated battery.Reference voltage source U1 and reference voltage source U2 can adopt TL431, and TL431 is a kind of parallel voltage-stabilizing integrated circuit.It is simple that this battery analogue circuit has structure, the advantages such as work noise is low, and dynamic perfromance is good, discharge and recharge automatic switchover, is suitable for simulating low-power battery.
