Description
Technical field
The utility model relates to the simulated testing system of the dynamic debugging functions of a kind of test battery management system SOC.
Background technology
SOC (is a state-of-charge; The ratio of capacity when the residual capacity of finger accumulator and its are full of electricity condition fully) be an important parameter of accumulator real-time status; It is the important evidence of battery management system adjustment battery charging and discharging state, adjustment loaded work piece state; Because of this parameter is a dynamic data; Be the dynamic value that battery management system calculates according to accumulator each item index of gathering, therefore when battery management system dispatches from the factory, must whether normally test the dynamic debugging functions of the SOC of battery management system.
Though have the software of the dynamic debugging functions of test SOC at present, when carrying out software test, seldom there is testing laboratory can reach the simulation of actual condition, there are following deficiency and shortcoming:
1. device-restrictive is put to the test; Simulated condition fully; Can not test the software all functions of battery management system; Because testing laboratory is just made with adjustable capacity analog electrical core, a lot of testing laboratories do not have the variation that this equipment can't analog electrical core capacity, the certain dynamic debugging functions that just can't test SOC.
2. the software of current battery management system is all tested when client is debugged about the SOC retouch in passing, often needs the change program in the test, causes client's the increase of follow-up work difficulty, work quantitative change big.
3. partly not test of the SOC of battery management system, more unusual in the client appearance, fraction defective is higher.
Above deficiency causes present battery management system debug difficulties, and fraction defective is high, and CSAT is low, unfavorable a large amount of productions.
The utility model content
In view of this, but the technical matters that the utility model will solve provides the battery management system SOC that a kind of real simulation electricity core accurately tests the dynamic debugging functions of the SOC of battery management system dynamically revises simulated testing system.
In order to solve the problems of the technologies described above, the utility model adopts following mode to realize:
A kind of battery management system SOC dynamically revises simulated testing system; Comprise test macro host computer and battery management system to be tested; Described host computer is connected with battery management system to be tested through the CAN card, and battery management system to be tested is connected with the analog electrical core of adjustable voltage through sample line.
As the improvement to such scheme, described analog electrical core is formed in parallel by a plurality of constant pressure sources with fixed voltage range.
Relative prior art the utlity model has following advantage:
1. the analog electrical core of this test macro is composed in parallel by a lot of constant pressure sources, and the variation through electric core in the voltage analog operating mode of regulating constant pressure source can change voltage very rapidly and accurately, be applicable to testing laboratory's test phase.
2. this test macro can be accomplished (the dynamic debugging functions of the SOC of current battery management system need arrive the client test) in testing laboratory for all functions test of battery management system; The software engineer can verify the software of writing at any time, shorten the development time.
3. reduced the fraction defective of battery management system; Improved CSAT; Battery management system all is through just issue use after the test passes, has reduced the phenomenon that client breaks down, and has improved the stability of product; Reduced debugging and difficulty after sale, increased the confidence of client product.
Description of drawings
Fig. 1 is the utility model embodiment circuit theory synoptic diagram.
Embodiment
Defective to prior art exists below will combine accompanying drawing describing in further detail the utility model for the ease of it will be appreciated by those skilled in the art that:
The battery management system SOC that present embodiment discloses dynamically revises simulated testing system and can accurately carry out simulation test to the dynamic debugging functions of the SOC of battery management system.
Shown in accompanying drawing 1.This simulated testing system comprises test macro host computer 1 and battery management system to be tested 2; This host computer 1 is connected with battery management system 2 to be tested through CAN card 3, and battery management system 2 to be tested is connected with the analog electrical core 4 of adjustable voltage through sample line.Wherein, this analog electrical core 4 is had voltage range and is formed in parallel for the constant pressure source of ± 5V by a plurality of.In the present embodiment, the host computer that adopted 1 is PC, in testing software is housed, can know that demonstration directly perceived understands the state of battery management system and analog electrical core 4.
During test, link to each other battery management system to be tested with PC through CAN card 3, and the other end of battery management system to be tested links to each other with analog electrical core 4, energized lets total system start working.Earlier be transferred to Full Charge Capacity to analog electrical core 4, i.e. upper voltage limit threshold values, this moment, the SOC of battery management system can show 100; Be transferred to 50% to the electric weight of analog electrical core 4 then, whether directly the SOC of observation battery management system this moment saltus step is 50; Be transferred to 15% to the electric weight of analog electrical core 4 again, whether the SOC that observes battery management system this moment can slowly be adapted to 15.Said process, if the SOC value is to change by the variation of analog electrical core 4 entirely, then the dynamic debugging functions part of the SOC of this battery management system is qualified.
The above embodiment has only expressed the embodiment of the utility model, and it describes comparatively concrete and detailed, can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
