Secondary battery performance testing
Preface: The device has 16 independent constant current control power supplies, each of which is completely independently controlled. It can simultaneously test 16 different types and specifications of combined batteries or single cells without interference. The charging and discharging process, charging and discharging current, and constant voltage values of each circuit are set and controlled by a computer
Parameters: Working power AC220V single-phase 50HZ charging and discharging current range 0.1-2A Current measurement accuracy ± (0.1% FS+0.1% RD) Voltage measurement range 0-10V, minimum discharge voltage 0V Voltage measurement accuracy ± (0.1% FS+0.1% RD) Time measurement range and accuracy 2000 minutes/work step, Accuracy ± 0.1% Internal resistance sampling range 0-600m Ω Internal resistance resolution 0.1m Ω Channel number 16 Maximum cycle setting number 2000 Maximum step setting number 25
Application range: It can detect almost all types of conventional single or combined nickel cadmium, nickel hydrogen, lithium-ion, and polymer lithium batteries. Each device has 16 independent constant current source control circuits, each circuit is completely independent of control, and can simultaneously detect 16 different varieties without interference The charging and discharging process, charging and discharging current, and constant voltage value of different specifications of combination batteries or individual batteries are set and controlled by a computer with powerful detection functions. The computer controls the testing voltage, current, and battery AC internal resistance testing function throughout the entire process. Voltage sampling interval ≤ 3 seconds, current sampling interval ≤ 48 seconds, internal resistance sampling interval ≤ 48 seconds
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
1. The testing industry is fully covered, meeting different testing needs
2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate
4. Free initial testing, with no testing fees charged
5. Self service order delivery for free on-site sampling
6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in China
