New battery pack test system at SLG operational since April 2018
Our new battery test system provides 20 additional test places for battery cycling for pre-test conditioning of batteries, for battery aging and life-cycle analyses.
The system can realise charging/discharging processes with a max. current of 62,5A and a max. voltage of 60V per channel as well as a max. power of 2500W per channel.
The equipment works energy-efficiently recycling the discharge energy from the batteries and feeding it back to the system for new charging cycles.
During the cycling process the battery temperature as well as the ambient conditions are constantly monitored.
Battery testing at SLG according to UL 62133:2015
The standard UL 62133:2015 for "Secondary Cells And Batteries Containing Alkaline Or Other Non-Acid Electrolytes" determines "Safety Requirements For Portable Sealed Secondary Cells, And For Batteries Made From Them, For Use In Portable Applications".
This North-American standard has been harmonised completely to IEC 62133.
SLG is a CB testing and certification body acknowledged for the BATT (battery) scope. We carry out tests according to IEC 62133 and can issue test reports according to UL 62133 if required.
Please note that for UL all safety-relevant components used in the battery must have a UL approval.
GENERIC48V project
SLG is a partner in the joint project "GENERIC48V". Together with other regional and national companies and institutions, we work on developing a Light Electric Vehicle LEV with the objective of obtaining approval for use on public roads. The project is supported by the Federal Ministry of Education and Research.
SLG will mainly be involved in the areas of battery testing and EMC testing as well as collecting legal and normative requirements prior to licensing the LEV.
As described in the project outline of Areus Engineering GmbH for LEV featuring a 48V on-board power supply "a new, integrated electronics design" will be developed as well as "an undercarriage [...] efficient and immune to electromagnetic disturbances. This undercarriage for three-wheeled as well as four-wheeled LEVs should then ensure an improved electromagnetic compatibility of the whole system."
