Erik Spek on battery abuse testing, improving safety, and developing standards

(This article originally appeared in Charged Issue 7 – MAR/APR 2013) Q&A with Erik Spek: The Chief Engineer at TÜV SÜD Canada on battery abuse testing, improving safety, and developing standards. When analyzing the current state of lithium-ion technology, it helps to look back at the development of the nickel metal hydride battery (NiMH). Some argued that hybrid automotive… Read more »

Researchers discover memory effect in Li-ion batteries

Scientists at the Paul Scherrer Institute (PSI) and the Toyota Central R&D Labs have reported a memory effect in lithium-iron phosphate (LiFePO4) batteries that appears after only one cycle of partial charge and discharge. Memory effects are well known to users of nickel-cadmium and nickel-metal-hydride batteries. If these batteries are recharged repeatedly after being only partially… Read more »

Rich Byczek on delayed battery overheating and stranded energy

(This article originally appeared in Charged Issue 6 – JAN/FEB 2013) EV standards gaps: Intertek’s Rich Byczek on two of the biggest safety concerns centered around batteries. The EV industry is young and evolving quickly – too quickly, in some cases, for the standards community to keep up.  The competing charging standards provide the most obvious example. There are… Read more »
