In-Situ Multi-Channel Battery Storage Gassing System

In-Situ Multi-Channel Battery Storage Gassing System   Characteristic 1. In-situ Storage Gassing testing for pouch cells 2. Multi-channel Testing (up to 64 channels) 3. Automatical Data Recording(volume, voltage and internal resistance) 4. Access to External Cyclers Description   1. Disadvantages 1) The temperature changes duringthe process result in gas generation and testing losses. 2) Manual data recording may introduce errors, as data collection must be done manually. Traditional – Oven & Balance Method  TMAX In-Situ Storage Method Equipment Setup Requires multiple devices: oven, voltmeter, balance, charging/discharging equipment Integrated equipment Equipment Functions Temperature change, volume, voltage Temperature change, volume, voltage, supplementary power Volume Measurement Precision       Low precision, > 50μL High precision, < 30μL Operation Mode  Complicated, requires transferring cells multiple times Simple, in-situ measurement, no transfer needed Data Recording    Manual multiple recordings Software automatic recording 2. Features 1) In-situ Storage Gassing testing for pouch cells 2) Multi-channel Testing (up to 64 channels) 3) Automatical Data Recording(volume, voltage and internal resistance) 4) Access to External Cyclers
