Hey Tesla folks,
just wanted to share my opinion on charging infrastructure.
When the e-car revolution is going to happen,(2020?) i think we would need BETTER stuff than only super-chargers.
Because the problem with e-cars is that not everybody has a nice garage where he can charge. And who wants to see an ugly cable jungle
on a street with all the cars parking? Wireless charging tech indeed is very simple and low cost.
I am a little bit dissapointed that Tesla isnt think of it YET. Since energy losses are very,very low(like 3% at 15cm distance).
Only thing you need is a very flat coil in the road and one very flat receiver coil on the bottom of the car.
Frequency of the voltage 50Hz needs to be transformed to few Khz with a variable frequency-drive. Thats all. Basically only a cable
ending in a spiral.
Also alignment with the field could be done easily via magnetic sensors. Also small disalignments are not really a problem.
Additionally the receiver coil should be movable forwards and backwards. All of course automatically. Tesla-style. ha
Not such a big deal IMO.
Also from a energy generating POV it will be necessary to charge all vehicles of a country evenly distributed over the day otherwise the power plant
requirements would be humongous(peak power). (remember, no internal combustion engines means we WILL need more power plants, batteries are not generating energy like ICEs, only storing)
Example: 1 million e-cars charging at 100kw= 100GW Extra plants needed, or everyone has his own wireless charging unit loading at 500-1000W. Basically trying to charge that amount that you needed the whole day evenly distributed whenever your car stands.
There are already a few companies selling inductive chraging pads for 2000 dollars.
But i think we need more of them. MUCH MORE.
I also like the comfort i hjave to confess. But from infrastructure POV i think this will be THE BEST solution.
You wont even notice that you are charging everyday. Charging evenly distrubted over a whole country.
An self-driving alignment feature would be also great.:biggrin:
What do you guys think?
