RE: Fast Chargers18 Jul 2019 21:56
In my long-held opinion, you're spot on Seaangler. For me it's the elephant in the room for EVs and the mainstream either doesn't see it or is ignoring it hoping it will go away. It makes me laugh when people say that Hydrogen just isn't ready, and yet they don't acknowledge that batteries and fast charging isn't ready either. They're still trying to develop higher power charger stations (as if 150kW isn't dangerous enough already). 350kW is going to require liquid cooled cables. Battery chemistry still doesn't like to charge that fast when either too flat or too full. As you rightly point out, 30 minute refills are going to require acres of charge points. And the batteries are just too damn heavy and expensive which is limiting most producers to 200-250 mile range. For my money hydrogen solves all this (except cost) as well as being the only solution for trains, trucks, buses, windfarm/solar storage, home heating, ships, (and possibly planes).
They have recognised that dead batteries will be a problem in the future which is why there are a host of second-life proposals...but to me that sounds like simply kicking the problem into the long grass. Recycling batteries is going to be more expensive than manufacturing from fresh raw materials and that cost isn't factored into the current vehicles either.
To me pure Lithium Battery EVs are the fluorescent bulb of the car market and FCEVs are the LED bulb, and many governments are in danger of backing the wrong one at this stage in both their developments, like they did with the dim, slow-to-start, fluorescent bulbs a couple of decades ago.
