Abstract
The utility model provides a battery test device that can be used to charge and discharge batteries. The utility model is characterized in that current direction regulating circuit, one end of the regulating circuit is connected to the battery and the other end is connected to the storage element.
Description
Technical field
The utility model relates to the battery testing machine that is used for battery is carried out the charge and discharge performance test.
Background technology
Can charge the secondary cell that uses repeatedly must be through repeatedly charge and discharge performance test before dispatching from the factory, and the battery testing machine obtains electric energy from civil power and charges into the battery during charging, during discharge electric energy is converted into heat energy and discharges.Because Ce Shi number of batteries is big simultaneously, and a large amount of heat energy that discharge behind the multiple discharge can make between test carriage in temperature raise, so must additionally install an air-conditioner or fan is lowered the temperature, increased production cost.For avoiding the workshop temperature too high, at present common recovery method is to adopt inversion to reclaim electric energy to the mode of electrical network, but when being power inverter, the shortcoming of this mode can cause the measuring accuracy of battery testing machine to descend, inversion specialized equipment manufacturing cost is higher, if the inversion transformation technique that adopts is immature, then may impact simultaneously electrical network.
The utility model content
The purpose of this utility model is to provide to avoid operating ambient temperature obviously to improve and lower-cost battery testing machine.
A kind of battery testing machine is characterized in that, is provided with the power flow regulating circuit, and the one end connects tested battery, and the other end connects energy-storage travelling wave tube.
Owing to be provided with the power flow regulating circuit, when tested battery discharge, regulate the power flow regulating circuit tested battery is discharged to energy-storage travelling wave tube; When need during, regulate the power flow regulating circuit and make energy-storage travelling wave tube to tested battery discharge to tested battery charge.During tested battery discharge, electric energy is stored in the energy-storage travelling wave tube, has avoided producing too much heat and has made between test carriage temperature too high, compare to the mode of electrical network with inversion, power flow regulating circuit and energy-storage travelling wave tube are simple in structure, and cost is low, and can not reduce measuring accuracy, can not impact electrical network.Electric energy is recycling between tested battery and energy-storage travelling wave tube, need not the repeat consumption electric energy to tested battery charge, has improved capacity usage ratio.
Description of drawings
Accompanying drawing is the utility model circuit diagram.
Embodiment
As figure, tested battery and energy-storage travelling wave tube respectively have two, and energy-storage travelling wave tube adopts battery in the present embodiment.The power flow regulating circuit comprises two pairs of metal-oxide-semiconductors, in every pair of metal-oxide-semiconductor, and the D utmost point mutual connection of two metal-oxide-semiconductors, metal-oxide-semiconductor is connected to the voltage source of being controlled by triple gate to the S utmost point of Q1.
Switch a3, switch b2, tested battery 2 and flow measurement resistance R 2 are serially connected between voltage source and the ground successively.Switch a2, tested battery 1, switch b1 and flow measurement resistance R 1 also are serially connected between voltage source positive pole and the ground successively.Bridge switch a1 between the contact of the contact of tested battery 1 negative pole, switch b1 and tested battery 2 positive poles, switch b2, the contact of switch a3, b2 connect the S utmost point of metal-oxide-semiconductor to Q2.
Switch b3, energy-storage travelling wave tube 3 and switch a5 are serially connected between metal-oxide-semiconductor another S utmost point and ground to Q1 successively, and switch a4 and energy-storage travelling wave tube 4 also are connected in series between metal-oxide-semiconductor another S utmost point to Q1 successively.Bridge switch b4 between the contact of the contact of energy-storage travelling wave tube 3 negative poles, switch a5 and energy-storage travelling wave tube 4 positive poles, switch a4, the contact of switch b3 and energy-storage travelling wave tube 3 positive poles is connected metal-oxide-semiconductor another S utmost point to Q2.
When tested battery needs when energy-storage travelling wave tube discharge, switch a1, a2, a3, a4, a5 closure, b1, b2, b3, b4 disconnection.Tested like this battery 1,2 forms cascaded structure, and energy-storage travelling wave tube 3,4 respectively by metal-oxide-semiconductor to Q2, Q1 parallel connection, thereby make tested battery 1 cathode voltage be higher than energy-storage travelling wave tube 3,4 cathode voltages, tested battery 1,2 just discharges to energy-storage travelling wave tube 3,4 to Q2, Q1 by metal-oxide-semiconductor.
When energy-storage travelling wave tube needs to tested battery discharge, switch a2, b1, b2, b3, b4 closure, switch a1, a3, a4, a5 disconnect.Tested like this battery 1,2 respectively by metal-oxide-semiconductor to Q1, Q2 parallel connection, and energy-storage travelling wave tube series connection, thus make energy-storage travelling wave tube 3 cathode voltages be higher than tested battery 1,2 cathode voltages, energy-storage travelling wave tube 3,4 just discharges to tested battery 1,2 to Q1, Q2 by metal-oxide-semiconductor.
Electric energy is the continuous loss of meeting in the process that circulates, and need replenish with voltage source, and this moment, Closing Switch a3, a4, a5 disconnected other switches, allow voltage source that energy-storage travelling wave tube 3,4 is charged by triple gate trigger voltage source.
Voltage source also can charge to tested battery.
Energy-storage travelling wave tube also can be an electric capacity.
The electric capacity of energy-storage travelling wave tube preferably is not less than tested battery, in order to avoid energy-storage travelling wave tube can not hold all electric energy that tested battery is emitted fully, causes waste of electric energy.
Power flow regulating circuit two ends also can connect tested battery respectively, and the tested battery at two ends is mutually as the other side's energy-storage travelling wave tube.
The power flow regulating circuit is not limited to the described physical circuit of present embodiment.
