Mr. SAVIN Jean-FrancoisWe have been using Neware benches for testing our primary cells and batteries for several years. We are quite satisfied about the quality of this type of equipment and we find always good and very reactive feedback from their after-sales service to help us in specific case.
Prof. Lv LiWe have been using Neware battery testing system for many years. We are focused on different electrochemical tests of lithium-ion batteries. The Neware machine is easy to be used and the program is easy to set. We have conducted charge-discharge cycling for more than 5000 cycles and the machine showed very good stability, which helped us to obtain
Mr. Frank GroenVarious neware testing systems have been equipped our laboratory for years and serves very good. We use them for many kinds of tests. Easy to handle the tests and data is well organized for our reporting work. The most important thing is the measurement and control are quite accurate and reliable.

Recycle Battery Function
If you have recovery battery pack , like Toyota Prius battery pack , generally, each piece has 6 single Ni - MH cell , then several pieces batteries assembed in one pack , and you need to check each single cell for capacity , cyclie life , resistance , etc . Then assemble the battery cell after sorting by capacity , resistance . You will get the new battery pack . And last you will test the battery pack to check the real capacity and other function parameter .
Simulation - the Way You Look into Reality
You know battery capacity at at constant current , or power , or load . But the reality is that no the energy is drawn by a constant variable . Your capacity or energy tested under constant conditions can only be a general one , and the cycle life tested such regime can also be largely deviated from reality . To have a better master of reality, simulation is introduced . GSM pulse is of such kind for phone batteries . for EV batteries , Drive Cycle Simulation is used .
Driving Cycle Simulation
Driving cycles are used to simulate car fuel economy at different operating conditions . There are many driving schedules or driving cycles that are issued by various agencies or institutes. To simulate EV , you need to convert the speed output into the power consumption or regeneration of the energy storage device installed on the vehicle .
Most of us are considering the voltage and current accuracies are the all important factors of a battery tester , but actually timing accuracy is of the same importance .
Capacity or energy is calculated on time basis with the voltage and current measured , thus the timing accuracy will greatly affect the capacity calculated . To a general constant current or other constant testing regimes, this effect may not that easy to be observed .
