One of the main disadvantages of electric versus conventional automobiles is the amount of time needed to charge batteries.
Since July 2016, the research project FastCharge, co-initiated by BMW and Siemens, has been trying to address that problem, and it’s been making progress. Researchers recently unveiled a prototype of an ultra-fast charging station on the Autobahn A8. It has a capability of 450 kW – a huge improvement over the mere 42 kW of 90% of all charging stations in Germany.
Before the new type of station can be used, today’s electric cars will also have to be modified to handle such a quick jolt of power. But BMW has carried out a successful test on an adapted i3 model. It needed only 15 minutes to charge from 10 to 80% and was able to take in enough power in only three minutes to drive 100 kilometers.
