Batteries, piercing the experimental temperature monitoring

Analog cell damage, test design, safety analysis heating curves and battery parameters such as surface heat distribution.

For details

Battery monitoring and local fever
Battery module temperature monitoring

To balance control of heating/cooling, temperature monitoring to ensure the quality and safety performance, and provide reference for the thermocouple loading installation.

For details

Charging and discharging test

Rechargeable batteries in the unit time to the rated capacity, monitoring OCV monitoring batteries different temperature points at the same time, establish OCV/SOC relationship curve model, to detect charged state.

03 monomer battery performance check

OCV, ACR, shell voltage testing

RongHuaCheng stages OCV tests to judge the trend of internal battery aging, test ACR in screening process high consistency of the battery, voltage detection shell to avoid defective insulation, and the same voltage test stands completed OCV/ACR/shell.

For details

03 monomer battery performance check

OCV temperature testing

OCV test at the same time focus on cell temperature changes, such as abnormal rise, there is risk of short circuit.

For details

04 battery module performance tests

Batteries and the temperature of the module test

To balance control of heating/cooling, temperature monitoring to ensure the quality and safety performance, and provide reference for the thermocouple loading installation.

For details

Battery pack factory inspection

Battery pack factory, need to spot check battery internal insulation and resistance performance of mass production, to avoid due to instability of the production process of the battery performance partial shift, ensure production batteries in the widest range of insulation and resistance performance of consistency.
