PEC offers cell and module testers ranging from low power desktop and rack mount cell testers all the way up to high power test systems for cells and modules. All systems are based on linear technology offering excellent dynamics and precision. Systems are typically used in R&D, product evaluation, life cycle testing and end-of-line testing.

PEC has raised the bar on its latest product releases, with 100 µsec based internal sampling, control and capacity calculations, hardware controls for both current and voltage* and a ± 0.005% FSD accuracy on the voltage readings*. All PEC systems have best-in-class features on board, such as 2, 3 or 4 automatically switched current ranges, ±0.03% FSD current control, better than 1 msec rise times, including range and mode switching transitions.
*On specific models only

Most commonly used climate chambers in the battery industry are directly controlled from the test channels, not requiring any third party software interface.

Most PEC systems offer an onboard temperature sensor per test channel. However this can easily be extended using our Auxiliary IO’s, offering analog and digital inputs, outputs, thermocouple inputs, NTC/PTC inputs, as well as BMS interface cards. All data collected from the IO’s can be used in your test programs, and outputs can also be set from the software.

In high-power test systems, thermal management is a significant challenge. Drawing on our extensive experience in water-cooled power electronics, PEC has innovatively eliminated unnecessary fans and implemented an internal cooling system. Initially introduced in our cell formation towers, this advanced cooling platform is now standardized across all new PEC test systems. As a result, our test systems not only provide superior performance but also create a quieter and cooler environment in your cell testing lab, doubling equipment lifespan while eliminating maintenance hassles.
