Li-ion Battery

Performance Evaluation

TECHNICAL OVERVIEW

Technical Overview

We conduct a health evaluation with high safety and reliability by synthesizing the IEEE standards for battery maintenance.


Periodic inspection is recommended for lithium-ion batteries.


Performance evaluation is carried out in various fields such as pack voltage, cell voltage, cell internal resistance, wiring resistance, temperature, and electrolyte leakage.


We provide expert consulting based on the results of battery health evaluation.

Soundness Evaluation Equipment 

Li-ion Battery Recommendations 

Recommendations for testing

Test Classification
Classify Inspection/Performance/Service Tests
Test Cycle
25% of life expectancy or 2 years, whichever is smaller
Every year when the difference of 10% or more from the previous test result or less than 90% of the rated capacity

Maintenance Inspection Recommendations

It is recommended by classifying it into monthly/quarterly/half-yearly/yearly special inspections.
Checking List
Pack voltage, cell voltage, cell internal resistance, wiring resistance, temperature, electrolyte leakage, etc.
It is recommended to conduct a performance test when a large change in internal resistance (30-50%) is detected or periodically (1-2 years)

Recommendations for testing

After the performance test, it is recommended to replace the battery if it is less than 80% of the capacity suggested by the battery manufacturer.

Development of Mobile Test Equipment 

PACT-Alliance periodically inspects the plant's UPS and ESS batteries by upgrading existing equipment to be portable.


When it is necessary to take out for uninterruptible power supply testing, it is possible to reduce costs through visiting testing.


We are developing and researching an On-Line Test System and test equipment to evaluate the health of lithium-ion batteries that are easy for users to access.
