Description
Technical field
The utility model relates generally to the detection technique field of electric battery, relates in particular to a kind of super capacitor carries out Non-Destructive Testing to the electric battery semi-manufacture circuit of using.
Background technology
Be connected in the process of BMS/PCM at electric core; Since processing procedure intrinsic defective; May cause the damage of BMS/PCM, after still in a single day electric core and BMS/PCM link together, receive the restriction of electric core capacity; Be difficult to quick and precisely adjust electric core voltage and charging and discharging currents, also just can't detect the function of BMS/PCM through external circuitry.Industry for low capacity electricity core, below 1000mAh, is taked big electric current mostly at present, the method that heavy load discharges and recharges, thereby in the hope of changing the function of electric core voltage checking BMS/PCM fast.The limitation of this method has 2 points:
1) can only be used for the less electric core of capacity;
2) electric core carried out the operation of big electric current super-charge super-discharge, be provided with like operating conditions and improperly then might damage electric core, and this kind damage is recessive that its harmfulness will just can display in the use behind product export.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, provides a kind of and can detect high capacity electricity core and can not damage the application super capacitor of electric core carries out Non-Destructive Testing to the electric battery semi-manufacture circuit.
The utility model is realized through following technical scheme:
Use super capacitor carries out Non-Destructive Testing to the electric battery semi-manufacture circuit; Include the electric battery semi-manufacture, the electric battery semi-manufacture include electric core, BMS/PCM, and described electric core parallel connection inserts BMS/PCM; It is characterized in that: also include super capacitor, described super capacitor is parallelly connected with electric core.
Described application super capacitor is characterized in that the circuit that the electric battery semi-manufacture carry out Non-Destructive Testing: the capacity of described super capacitor and ESR and electric core are complementary.
Described application super capacitor is characterized in that the circuit that the electric battery semi-manufacture carry out Non-Destructive Testing: described super capacitor also is in series with two parallel with one another, opposite polarity diodes, and the other end of two diodes connects a single-pole double-throw switch (SPDT).
The principle of the utility model is:
Super capacitor and the parallelly connected formation of electric core shunting circuit that the utility model is complementary capacity and ESR and electric core.Utilize the characteristic that super capacitor can high power charging-discharging, it is discharged and recharged, thereby in the BMS/PCM major loop, produce the performance of big electric current with test b MS/PCM.
When charging measurement; Make the voltage of super capacitor be equal to or slightly lower than electric core voltage through control circuit; But ESR hinders well below electric in-core, forces most of electric current flow through super capacitor rather than electric core; Thereby avoided the infringement of large current charge to electric core, the effect that can simulate large current charge has simultaneously again detected the performance of BMS/PCM.
When discharge test; The voltage of super capacitor is equaled or a little more than electric core voltage through control circuit; But ESR hinders well below electric in-core, forces most of electric current to be provided by super capacitor, rather than electric core; Thereby avoided the infringement of heavy-current discharge to electric core, the effect that can simulate heavy-current discharge has simultaneously again detected the performance of BMS/PCM.
The utility model has the advantages that: the utility model is simple in structure, realization is convenient, has avoided the infringement of large current charge to electric core, has realized the performance detection to BMS/PCM.
