European e-Call System.

The European commission will implement the automatic emergency call system e-Call by the beginning of 2018.


This emergency system provides information about position of the car, extend of damage and allows the insured person to talk to an emergency call centre. Chances for rescue and

reduced severity of damage increase significantly.

The Battery challenge.


The combination of GPS and GSM system and the need to have sensor data from various positions inside the car requires an independent system with powerful battery that is able to reliably work in the harsh automotive environment over the extended temperature range. Battery must be robust to withstand car crash and be steadily available at any time.
