Smartphones & Co.
Burning smartphone batteries showed recently that the ever-increasing pace of technical development means that the lithium-ion battery safety requirements also have to be brought in line due to the increasing energy levels involved.
The experts at VDE|DKE have therefore supplemented the existing standard DIN EN 62133-1 (VDE 0510-81), which mainly covers nickel-cadmium and lead batteries, with a new, second part, DIN EN 62133-2 (VDE 0510-82), which specifically refers to the requirements for lithium-ion batteries. Part 2 of the standard contains requirements and tests for the safe operation of such batteries.
For example, the standard deals with what happens if a battery is inserted incorrectly into a laptop. It specifies how smartphone safety can be improved in the event of a fault by carrying out corresponding advance checks.
Stationary and mobile applications in industry
While DIN EN 62133-1 and -2 (VDE 0510-81 and -82) are limited to batteries in portable devices, the newly published DIN EN 62619 (VDE 0510-39) focuses on industrial applications with lithium-ion batteries.
The standard thus covers e.g. the requirements and tests for stationary applications such as telecommunications or emergency power supplies. It also includes mobile applications such as those used in railways, shipping and other areas (such as forklifts and golf carts).
