[ detailed description ] embodiments
The following detailed description of embodiments of the invention refers to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention is a battery discharge test circuit, which includes a battery positive terminal, a battery negative terminal, a sampling resistor R1, a sampling resistor R2, a discharge resistor R3, a resistor R4, a resistor R5, a setting resistor R6, a resistor R7, a resistor R8, an adjusting resistor R9, an adjusting resistor R10, a capacitor C1, a triac Q1, a transistor Q2, a power supply terminal VCC, a voltage comparator AR1, and an alarm unit LS 1. For example, the voltage comparator AR1 is an operational amplifier, such as a differential amplifier circuit with an operational amplifier circuit in an open loop state.
As shown in fig. 1, a battery positive terminal, a regulating resistor R9, a resistor R5 and a battery negative terminal are connected in sequence; preferably, the battery positive terminal is connected with the circuit fuse F1, the positive electrode of the reverse connection prevention diode D1 and the negative electrode of the reverse connection prevention diode D1 in sequence and then is connected with the adjusting resistor R9. In another example, the positive terminal of the battery is connected to the sliding terminal of the regulating resistor R9, or the positive terminal of the battery is connected to the sliding terminal of the regulating resistor R9 after being sequentially connected to the circuit fuse F1, the positive terminal of the anti-reverse diode D1, and the negative terminal of the anti-reverse diode D1. The battery positive terminal is connected with the positive electrode of the external battery to be tested, the battery negative terminal is connected with the negative electrode of the external battery to be tested, namely the battery positive terminal and the battery negative terminal are respectively connected with the positive electrode and the negative electrode of the external battery.
The resistor R5 and the negative terminal of the battery are grounded; that is, the positive terminal of the battery, the regulating resistor R9 and the resistor R5 are connected in sequence and then grounded, and the negative terminal of the battery is grounded.
The discharge resistor R3, the first main terminal of the bidirectional thyristor Q1, the gate of the bidirectional thyristor Q1 and the resistor R4 are connected in sequence and then connected in parallel with the adjusting resistor R9; that is, a circuit formed by connecting the discharge resistor R3, the first main terminal of the triac Q1, the gate of the triac Q1 and the resistor R4 in series is connected in parallel with the adjusting resistor R9. And, the second main terminal of the triac Q1 is grounded. Thus, the battery forms a discharge loop through the discharge resistor R3 and the triac Q1, so that the battery is discharged; the discharge current can be set by using the adjusting resistor R9 as a discharge current adjusting resistor and changing the conduction angle of Q1 by the adjusting resistor R9. That is to say, the magnitude of the resistance of the adjustable resistor R9 is adjusted to set different magnitudes of the discharge current and the discharge voltage, so as to implement the simple discharge test circuit according to the embodiments of the present invention, so as to meet the discharge test requirements of different batteries, thereby solving the problems of inconvenience and low test efficiency caused by the requirement of different test circuits for different batteries. Preferably, the sliding ends of the regulating resistor R9 are respectively connected with the positive terminal of the battery and the discharge resistor R3. In another example, the resistor R4, the gate of the triac Q1, and the second main terminal of the triac Q1 are connected in series and then connected in parallel with the resistor R5.
The battery positive terminal, the sampling resistor R1, the sampling resistor R2 and the battery negative terminal are connected in sequence; that is, a circuit formed by connecting the sampling resistor R1 and the sampling resistor R2 in series is connected in parallel with a circuit formed by connecting the adjusting resistor R9 and the resistor R5 in series. The battery positive terminal, the sampling resistor R1, and the sampling resistor R2 are connected in sequence and then grounded. Thus, the resistor R1 and the resistor R2 are used as sampling resistors for the battery voltage, and the two resistors are divided to form the sampling voltage Vbt.
The capacitor C1 is connected in parallel with the sampling resistor R2, and a sampling point is arranged between the sampling resistor R1 and the sampling resistor R2, as shown in fig. 1, for acquiring the sampling voltage Vbt; the power source terminal VCC is connected to the setting resistor R6 and the adjusting resistor R10 in this order and then grounded, and a reference point is provided between the setting resistor R6 and the adjusting resistor R10 to obtain the reference voltage Vrf. Thus, the resistor R6 and the resistor R10 are used as reference voltage setting resistors of the comparator circuit, and both resistors are divided to form the reference voltage Vrf. Thus, the reference voltage Vrf can be changed by adjusting the adjustable resistor R10, so that the battery discharge voltage value can be changed to adapt to different battery discharge voltages. Preferably, the sliding end of the adjusting resistor R10 is connected to the setting resistor R6.
The inverting input end (namely, the negative end and the negative end) of the voltage comparator AR1 is connected with the sampling point, the non-inverting input end (namely, the positive end and the positive end) is connected with the reference point, the power input end is connected with the power supply end VCC, the grounding end is grounded, the signal output end Vout outputs a level signal, and the level signal is grounded after being sequentially connected with the resistor R7 and the resistor R8; the base of the transistor Q2 is connected between the resistor R7 and the resistor R8, and the emitter is grounded. Preferably, the transistor Q2 is an NPN-type transistor
The alarm unit LS1 is respectively connected with a power supply terminal VCC and a collector of a triode Q2. For example, the alarm unit is a Speaker (Speaker), a buzzer, an LED lamp and related circuits, when the sampled voltage Vbt is lower than the reference voltage Vrf, the comparator AR1 outputs a high level to drive the transistor Q2 to be turned on, and the alarm unit LS1 is turned on and emits sound and/or twinkles light to prompt the user. For example, when the battery voltage continuously drops and the sampling voltage Vbt continuously drops during the discharging process of the battery, when the sampling voltage Vbt is smaller than the reference voltage Vrf, the comparator AR1 outputs a high level to drive the transistor Q2 to be turned on, the buzzer is turned on and sounds, and the discharging voltage is indicated to be reached.
In the battery discharge test circuit, the battery positive terminal is connected with the circuit fuse F1, the positive electrode of the anti-reverse diode D1 and the negative electrode of the anti-reverse diode D1 in sequence, and then is connected with the sampling resistor R1, the discharge resistor R3 and the adjusting resistor R9 respectively. The circuit fuse F1 is adopted, so that the damage of a rear circuit and the generation of large current to damage a battery to be tested can be prevented; and an anti-reverse diode is adopted for preventing the input end of the battery from being reversely connected to cause circuit damage. Therefore, the discharging current and the discharging voltage of different batteries can be realized by directly adjusting the adjustable resistor, and the problems of inconvenience and low testing efficiency caused by different batteries needing different testing circuits can be solved.
The battery discharge test circuit applied to the above embodiments and combinations thereof further comprises a voltage display table V1 and a current display table V2; the negative electrode of the reverse connection prevention diode D1 is connected in series with a current display meter V2 and then is respectively connected with a discharge resistor R3 and an adjusting resistor R9; the current display meter V2 is connected in parallel with the voltage display meter V1 after being sequentially connected with the discharge resistor R3, the first main terminal of the bidirectional thyristor Q1 and the second main terminal of the bidirectional thyristor Q1. Thus, the battery voltage and the battery discharge current can be visually observed by the voltage display table V1 and the current display table V2. For example, the conduction angle of the Q1 is changed by adjusting R9, the discharge current is set, and the discharge current can be displayed through a V2 ammeter so as to adapt to different battery discharge currents and have good compatibility.
In the battery discharge test circuit, the resistor R5, the battery negative terminal, the second main terminal of the triac Q1, the sampling resistor R2, and the capacitor C1 are connected to the common ground of the voltage display table V1, and the adjusting resistor R10, the ground terminal of the voltage comparator AR1, and the resistor R8 are connected to the common ground of the emitter of the transistor Q2.
