Battery Cycle Test

What is Cycle Test?​

The battery cycle test refers to the task of repeating charging and discharging the battery hundreds of times using cyclers for several months
under various conditions, such as voltage, current, pressure, temperature, and rest period.​

Tests generate data on battery voltage, current, capacity, internal resistance, temperature, time required, energy efficiency, impedance, etc.
for battery design verification and safety, reliability, and lifespan evaluation.​

Cycle Tests in
Battery Value Chain​

Why are cycle testing
services required?​

  • The increased demand for secondary batteries for EVs and ESS is
    expected to boost the demand for evaluation as well.​

  • Data distributed by department and project impedes seamless access
    and usage.​

  • Construction, maintenance, and expansion of environments such as
    evaluation equipment and SW incur high costs.

  • Relying on manual data collection poses potential reliability issues,
    including contamination.​

  • Data organization and report writing tasks are monotonous, repetitive,
    and inefficient.​

  • It is demanding to monitor revaluation progress and real-time data.​
