Description
Technical field
What the present invention relates to is the field of measuring technique of power cell source.
Background technology
Power cell source refers to the electric battery that very strong driving force can be provided.It is applicable to every application scenarios that need the high energy battery power supply such as hybrid vehicle, electric automobile, portable station, Mobile Data Base Station.Power battery pack generally is to be in series by multiple batteries.After the multiple batteries series connection, each battery charging and discharging unbalanced phenomena in use can occur, be embodied in that overcharging appears in the part battery or cross to put and to cause the part battery to damage and influence whole battery group performance and life-span etc. as not adding control.Energy SOC (State of Charge as battery; be called for short SOC; be battery electric quantity) can be lower than other batteries; if continue discharge; then when assembled battery total voltage does not also drop to protection voltage; the voltage that some single battery can occur has dropped to the lower limit of this batteries, if continue the permanent damages that this batteries will appear in discharge again.But prior art is measured the working current of electrokinetic cell and the meter of the energy SOC of battery is counted in the bigger error of existence, measured slow, the timely alarm of response speed, and causes single battery overvoltage or under-voltage and damage.
Summary of the invention
The objective of the invention is in order to solve prior art, and cause single battery overvoltage or under-voltage and problem damage to the operating voltage of electrokinetic cell, electric current, temperature survey with to the measurement of the energy SOC of battery and calculate to go up and have bigger error, measure slow, the timely alarm and can not carry out Real-time Monitor Management of response speed to the course of work.And a kind of method of test of power cell source is proposed.
Steps of the method are:
Step 1: initialization microprocessor chip 2, display circuit 3, multiselect one analog switching circuit 1, CAN transceiver 4; Contrast potential parameter, contrast current parameters, reduced temperature parameter set up standard;
Step 2: after periodic voltage, electric current, the temperature data of each battery of the battery source that microprocessor chip 2 will collect by multiselect one analog switching circuit 1, electric voltage equalization testing circuit 12 carries out the A/D conversion, be converted to numerical value again, compare with the contrast potential parameter that pre-sets, contrast current parameters, reduced temperature parameter respectively then, when comparative result for not within critical field, when being excessive or too small, then do abnormality mark; And with above-mentioned all data storage in a data set; And real-time waiting timer subroutine interruptive command;
Step 3: the data set in the step 2 is handled, will do not had the data conversion storage (in memory bank that outage back data are not lost) in another data set of abnormality mark in the data set; All stored data are used for the instant extraction of keyboard subroutine interruptive command and handle, show and report to the police; When the numerical value in the data set had abnormality mark, then microprocessor chip 2 was promptly carried out the operation of reporting to the police by 6 work of feedback module circuit 5 guide sound light crossing-signals; And real-time waiting timer subroutine interruptive command; Return operating procedure two.
The present invention can carry out measurement and monitoring in real time accurately and fast to the energy SOC of operating voltage, electric current, temperature and the battery of power cell source, phenomenon generation and sound and light alarm prompting in real time that it can prevent battery over-discharge and overcharge, and having prolonged life-span of battery, it also has the advantage that step is simple, be easy to apply.
