The simulation center mainly comprises a high-precision resistor, a low-impedance MOSFET, a high-precision digital programmable power supply and a high-stabilization-degree switch power supply. The function analyzer has the advantages of being capable of well adapting to practical production situations and being used, clear in function and capable of carrying out tests quickly and conveniently, and facilitating simple operations for workers.
Description
Technical field
Type of the present invention relates to technical field of lithium batteries, is specifically related to a kind of novel semi-automatic li-ion cell protection plate functional analysis instrument.
Background technology
Since Sony in 1992 successfully developed first commercial li-ion battery, the lithium electricity was with its high-energy ratio, long-life, high platform voltage, and characteristic widespread use aspect portable type electronic product such as environmental protection.In recent years, also raise year by year in its market share of electrokinetic cell field.Though lithium ion battery other secondary cells relatively has lot of advantages, the characteristics that itself exist not overcharging resisting and not anti-mistake to put need peripheral holding circuit that it is protected, i.e. our usually said fender.The quality of fender is determining it for the protective capability of lithium battery, thereby it is detected just seems particularly important.Traditional fender tester, function complexity, measuring accuracy are not high, and testing efficiency is low, are unfavorable for the easy of production practices simultaneously.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art and a kind of efficient height, clear, the easy to operate novel semi-automatic li-ion cell protection plate functional analysis instrument of function is provided.
For reaching above purpose; the present invention adopts following technical scheme: a kind of novel semi-automatic li-ion cell protection plate functional analysis instrument; comprise Simulation Center; MCU, host computer, described host computer and Simulation Center communicate to connect; described host computer is connected with the Simulation Center two-way communication with MCU, MCU; described Simulation Center is mainly by high-accuracy resistance, Low ESR MOSFET, and high accuracy number programmable power supply and high voltage stability degree Switching Power Supply are formed.
The invention has the beneficial effects as follows: can adapt to the production actual conditions better and use, function is clear, be convenient to the staff oversimplifies operation, and can fast test rapidly.
Description of drawings
In order to be illustrated more clearly in technical scheme of the present invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural drawing of the present invention.
Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is explained in detail; in conjunction with Fig. 1; a kind of novel semi-automatic li-ion cell protection plate functional analysis instrument comprises Simulation Center, MCU; host computer; described host computer and Simulation Center communicate to connect, and described host computer is connected with the Simulation Center two-way communication with MCU, MCU, and described Simulation Center is mainly by high-accuracy resistance; Low ESR MOSFET, high accuracy number programmable power supply and high voltage stability degree Switching Power Supply are formed.Described precision resister is by carrying out dividing potential drop to the switch power source voltage, and then the whole Battery pack group of control, carries out dividing potential drop by the voltage to digital programmable power supply, and then the variation of single electric core in the whole Battery pack of simulation.In total system, the high-accuracy resistance of simulation single battery is controlled by two-way MOSFET.When selecting one the tunnel, corresponding MOSFET conducting can be adjusted the voltage of whole battery group.Simultaneously, during the MOSFET conducting of another road, can very accurately control each string, it is carried out isolated operation accurately.The high accuracy number programmable power supply can carry out communication with upper computer software, utilizes the high precision of the powerful programing function of upper computer software and this power supply, can test fender with the stepping of 1mV, really accomplishes in real time with stable.High voltage stability degree Switching Power Supply is made up of a series of Switching Power Supply, mainly is the dissimilar electric battery of simulation,, for some unconventional voltage, can revise the seamless test of voltage in the realization scope by adjusting its inner potentiometer as 24V, 48V etc.Described MCU belongs to lower computer system in this system, by with upper computer software real-time Communication for Power, the relay of Simulation Center is carried out valid function.Built-in data acquisition system (DAS) is carried out high-speed sampling to aanalogvoltage information, is the digital signal that MCU can identify with analog signal conversion, and the information of programmable power supply is better passed to upper computer software, carries out stored record.Host computer adopts software control, utilizes the powerful graphical interfaces function of VC, makes more intelligence and clear of operation interface.Upper computer software is monitored the situation of lower computer system in real time, and the control programmable power supply pressurizes and reduces pressure fender in set mode, and records final fault value information, and the data of record are carried out aggregation process, imports database.
The above person is preferred embodiment of the present invention only, is not to limit practical range of the present invention, and namely all equalizations of doing according to the present invention change and modify, and are all claim scope of the present invention and contain, and give an example no longer one by one here.
