When trying to solve REALLY BIG riddles sometimes the best thing to do is Deep Dive and then Walk Away.
Walk away for an hour
Walk away for a day
Walk away for a week
Walk away for a month
Walk away for a year
Bigger the problem
Longer the time you spend reflecting
...
During this reflection period it is very common to find many false leads that may appear to side-step the problem. Write these leads down on a board
Bubbles
Lines connecting Bubbles
Capture the full System with inter-dependencies
... A primary difference I have noticed between circular thinkers (quacks) and epic geniuses is this ability to maintain the wide and narrow focal point at the same time.
Anyway...
(Sitting at home sick. Eating Chinese Food for breakfast...)
I recently became aware of this DIY BMS Master than can speak with the Slave Modules of the top tier OEM Battery Modules. That was a huge missing puzzle piece in this solution set.
...
To brainstorm a bit
We are having great issues with Grid Infrastructure
Many have lined up AGAINST EV Progress
...
I think the solution is to Side Step the argument
Re-Focus on Energy Independence
Develop Solar and Inverters
Develop (Mobile) Stationary Storage
Worry less about Protocol (like CCS1 and all the garbage in this thread)
Worry less about Connector type (see above)
Worry more about just standardizing on the actual mechanics of what is going on
So
Back to basics
There is DC
There is AC
Solar creates DC
Random DC
Cars can take AC (up to 10KW) or DC (up to 100KW)
Cars at home need not charge fast
Internationl Standard is AC
J1772 is quite simple
... Solar + Inverter + GridTie + any attempt at sationary storage
(To drive the inverter industry to support it)
(even if it is a 1Ah battery... it must be there in the system!)
...
This takes me away from this big fight about getting this garbage CCS stuff working.
I can tell when something has been made to be overly complicated by its nature.
A slow-down
A stumbling block
....
Meh
X-10 Modules are super simple
CCS Charging EV's is a black hole
This... Comms over Power is susceptible to mistakes so it carries no magic safety... It is no more safe than wireless comms.
...
Every car has Bluetooth
Most cars have 3G or better Internet connection
Cars are becoming wireless
Authentication is easy
Serial numbering is easy
Safe Wireless is easy
Meh -
Every bone in my body says that this is not the solution we want to continue working toward. The big Charge Companies have eliminated low voltage support.
...
First we must simplify the protocol
Second we must drive down the cost and complexity of the Interconnects
...
I still think the ultimate solution is a 3rd Option
Option 1) Drive 240V AC into Car
Option 2) Drive 200V - 1000V Clean DC into Car
Option 3) Compromise
Back in the Think Tank days the best idea (which did not win) was to
TRANSFER DIRTY POWER
Dirty Power can be anything
It can be Bi-Polar or Unipolar
It can be Steady DC or Chopped
It can be 50hz or 50khz
It really does not matter
Dirty Power. . . is almost as easy to deal with as Standard AC
...
The question becomes:
"How small and light of a "Dirty Power to DC Charge" Converter can you create?
We would want these to be 10KW bricks
Automobiles could put 1 to 15 bricks in their car
Bricks could be swapped out
Yes...
It is some dead weight to carry around...
What you would get from the dead weight is
the ability to plug your car into anything.
Found a 120V AC socket? Plug it in.
Found a 240V AC socket? Plug it in.
Found a 480V AC socket? Plug it in.
Found a big DC source? Plug it in.
Found a hella choppy, super noisy, wicked bunch of shit? Plug it in.
That is where things need to go if we are going to scale massively.
An Electric Vehicle needs to be able to charge off of anything it can find in any form.
Forget these people who are trying to take control of the industry and put themselves in a middle-man position to profit greatly...
You do not need a CHAdeMO connector
You do not need a CCS1 connector
You do not need a CCS2 connector
You do not need a Tesla connector
You do not need. . . to conform... to anything - IF - You have onboard Conversion and Protection....
...
Your Trunk or Frunk can open up to have any number of adapters in there.
Yea - at first - it will be a Nerd Mess... but... the market will take over from there and fix things
... The most BASIC of comms are all that is needed. Even the extended J1772 can handle it
KISS
Keep It Simple Stupid
I... am seeing startups fail and lose runway.... over total BS
... Think outside the box and remember that sometimes we have to throw away a lot of work to start clean.
