      Battery Division


    ▣ It is a charger/discharger that can test the characteristics of secondary batteries. It is a device that inspects battery characteristics and life time at the research institute/quality inspection/development stage.

    Features and Advantages

    - Pulse Type cycler

    - Driving pattern simulation of electric

    vehicles is possible.

    - Apply high current for actual use in mass

    production process


    ▣ Formation refers to the activation process that

    completes the characteristics of a secondary battery after

    the secondary battery assembly is completed.

    K&C Co., Ltd. is the first in the world to apply a pulse type,

    enabling groundbreaking formation control.

    Features and Benefits

    - The charging time is more than twice as fast as the

    existing charge/discharge process.

    (Tact Time 50% ~ 65% reduction effect)

    - Securing battery stability during high-speed

    charging (extension of battery life by 12 to 31%)

    - High current resistance is secured by applying a

    high current with a pattern similar

    to that actually used in EV vehicles.

    · Basic concept of pulse type charging

    High value current charge and low current

    discharge within a short time alternating method

    Normal Type

    Pulse Type

    · Comparison of K&C pulse charging and other

    companies' pulse charging


     * Required input data

    Normal Type

    Pulse Type

    · Advantage of Pulse Type Charging

    Normal Type

    Pulse Type

    - The same capacity charging time is reduced from

    100 seconds to a maximum of 30 seconds. It is

    reduced by about 50% as a general test experience.

    · Charging result

      Experimental condition :

      Pulse 1.0C / Pulse 1.56C / Normal 1.56C

    Pulse : 1.0C

    Pulse : 1.56C

    Normal :

    1.56C

    - In general, the chemical conversion process is

    carried out at 0.4C ~ 0.6C, and charging is possible

    without damage at more than twice the charging

    speed when charging with Pulse Type.


    ▣ Supports Direct DCIR method / Excellent

    precision compared to other domestic and

    foreign equipment.

    Features and Advantages

    - DCIR measurement required by IEC should be

    measured at 0.01sec, but the current

    Hwasung process DCIR measurement is

    conducted at 10sec, 1.5C.

    - K&C Co., Ltd. Pulse Type DCIR is implemented at

    0.01sec, 4~6C, and it meets IEC requirements.

    · DCIR measurement method

    1. constant voltage

    2. Discharge in CC (constant current) mode under

        class conditions

    3. ΔU3(drop voltage) measurement

    4. DCIR calculation



    · DCIR measurement important technology

    1. Accuracy of current capability and current control

    corresponding to Class (1 to 4)

       * Current control (Tr/Tf time and charge/discharge

          switching characteristics)

    2. ΔU3(drop voltage) record interval technology to measure

    | Comparison of precision and characteristics of 

       KNC and existing equipment
