Battery charge and discharge test



Methods to Construct a Battery Charging and Discharging System


  Turn keyEntrust SI to purchase Turnkey Self-construction Construct independently through the suggested development platform

Save time and energy
Battery manufacturers only need to focus on material and formula research and process optimization, and all test issues are handled by SI

The self-constructed system can be adjusted according to the change of requirement, which is more flexible than the dedicated system

With self-construction flexibility, the simple platform can quickly complete automated testing procedures without professional software engineers


After the system is installed, it is dedicated, and there is no flexibility for adjustment

It is necessary to hire full-time and professional software engineers. If the engineer were to quit the job, it would cause system maintenance issues None

Battery charge and discharge test
(Construct independently through the suggested development platform)




In the past, the equipment could not be connected to the Internet,

and the process data had to rely on manual or semi-automatic collection of information


High time and labor costs for managing equipment and data







Through GW Instek's MetaLab and MetaView metaverse solutions

Complexity is managed by simplicity, greatly reducing the overall cost of test deployment and management
