The testing center is a department with the function of product full inspection and QC education. It is responsible for the quality of product from both production line and samples. It also provides testing data and evidence of product modifications in the design sessions. The testing center has the major responsibility for the reliability and security of batteries and chargers; the calibration and management of quality project and equipments. It is a solid backing for the quality control system.

There are five major testing areas in the testing center: charger testing area, PCB testing area, battery cells testing laboratory, testing chamber for high and low temperature and final products testing area.

Testing Capability of the testing center

1. The testing center is responsible for the confirmation of the performance (charge and discharge mechanism, discharging in different rate, cycle life and electricity retention ability) of new incoming cells including Ni-MH,Ni-Cd,cylinder Li,soft pack Li, IFR and so on.

2.The testing and confirmations of PCMs are mainly for Lithium battery and LiFeSO4. The testing terms includeovercharge protection, overcharge recovery, over-discharge protection, over-discharger recovery, over current, internal resistance, self consumption, balance starting, communication function, short circuit protection etc.

3.The testing and confirmation of chargers applies on Ni-MH battery chargers, Lithium battery chargers, LiFeSO4chargers, various balance chargers and adaptors.

4.The samples from the R&D department will be strictly inspected according to IEC and GB/T 18287-2000 standards. The testing terms include free fall, vibration and abuse experiments. The actual capacity of the samples will be accurately measured to see if they meet the design requirement. Besides, aging tests are also applied to the samples in order to find the current and potential quality problems. The testing center will guide the mass production only after the safety of the products is ensured.

5.The OQC department will stick to the testing standards and do sampling inspection on every batch of products to guarantee the quality. It is also their responsibility judge the quality of the products with the lowest cost, time and fewest product samples. In addition, they will be playing an important role in improving the manufacture process and the quality of final product. The cutting-edge equipments in the lab are capable of recording the data in the charging/discharging process and can be easily managed by graphical display. It is very convenient to review and trace back the manufacture process.

6. Reliability Laboratory

The reliability lab is responsible for testing the reliability of battery cells under abuse conditions (25±2℃ external short circuit, over charge , thermal shock, impact, nail penetrating, crushing, projectile and free fall). It is built strictly according the ISO requirements and helps obtaining UN38.3 certificate for all our products in order to guarantee the safety during transportation. In addition, it can help meet customers' non-technical requirements and improve our international competitiveness.

7.Thermostatic Laboratory

Thermostatic laboratory provide the thermal adaptability tests (charging and discharging experiments high temperature, low temperature, constant humidity and special environment using different charge rate) of battery cells and packs. The equipments can provide a highly reliable testing environment effectively.
