High Voltage

High voltage for efficient charging and energy storage

orange line
Large electrical vehicles put high demands on the charging. It needs to be fast and efficient to meet today's challenges.

Larger vehicles demand high voltage

As larger vehicles are becoming electrified, high-voltage products have become more common. For powerful vehicles and machines, internal combustion engines have so far been the only alternative. Many authorities and environments nowadays require fossil fuel-free vehicles, a fact, which has increased the high voltage development pace. More power efficient battery chemistries have been developed and smart modular concepts of batteries have paved the way for electric forklifts, commercial vehicles and other industrial machines.

High voltage - from 24-120VDC to 400-800VDC

The machines of today have larger power needs and also larger energy content in batteries, in order to extend time between charging. That creates higher demands on the charging occasions, since it needs to be fast and more efficient. To avoid excessive currents, it has become necessary to increase the electrical voltages. In the past, 24-120VDC was sufficient, while today it is increasingly common with secondary voltages of 400-800VDC.

Integrated high voltage charging

The new high-voltage technology enables complete battery systems where both the vehicle and the battery with charger are fully integrated. This is the foundation for both fast charging and onboard charging.


High voltage also facilitates energy storage, both for cable dimensioning reasons and for the fact that the conventional 3-phase mains voltages 3 x 380-480V are closer to the corresponding rectified voltages 400-800VDC.
