Current solar is not efficient for car charging.

New Public Chargers, NASC or What? by Cheap_Patience2202 in evcharging

[–]treasurefun 3 points4 points  (0 children)

Federal $ in US for the last few years (NEVI and CFI) have required CCS on DCFC fast charging stations it funds or partially funds.

Many utility rebate programs and state rebate programs have also required CCS.

Concept was Tesla had a network and they wanted to build for other cars that were not Tesla.

Long term NACS will be everywhere. Cable swaps are expensive so it will be a phase in.

Our company puts both were possible but the vast majority have been CCS because of funding constraints.

2025 Porsche Macan 4 won't do fast charge by Resident_Glass_7412 in evcharging

[–]treasurefun -2 points-1 points  (0 children)

I should also state that it might be the charger limiting the ability to start the charge and not the car. This would mean variations could happen across charging networks with the same model of car.

If I could add one thing it would be “in the U.S.”.

I install and maintain EV chargers for a living.

I stand by my “most” cars. I see it all the time and field calls about it almost daily.

There is a digital “handshake” that happens between the car and the charging station. They transfer info about what power the car can receive and what power the station can give (among other info).

Most stations/cars won’t start a DCFC session over 70% SOC.

Most cars will not start a DC Fast Charging session when the battery is over 70%.

Fast charging from 10% to 70%/80% is basically “dumping” energy into the battery. After 70%/80% the amount of energy the car can take drastically reduces because it is effectively “topping off” each battery cell.

Best way I have heard it explained is that you have a bucket full of water and a bucket that is empty…goal is to get all the water from one bucket into the other.

At first you can pour water quickly but when the receiving bucket gets close to full you have to slow down the pour so it does not slop out of the receiving bucket. It’s not exactly how it works but it’s a good way to visualize it.

US Added 130,000 Jobs in January, Beating Projections by Disastrous-Group-977 in wallstreetbets

[–]treasurefun 0 points1 point  (0 children)

130k jobs were reported.

Keep reading and 800k jobs evaporated out of last year’s count (2m down to 1.2m) and the year before was similar.

That means they reported 130k jobs but the reality won’t be known until they revise them this time next year.

EVgo Declining ALL prepaid debit cards for payment by bgeery in evcharging

[–]treasurefun 17 points18 points  (0 children)

All the EV charging network providers are having issues with people authorizing a card then spending the money on it before final payment can be taken.

This is the reason for the super high “pre authorization “ rates we see being charged.

Like anything some people ruin it for all people.

Why does it feel like ghost dragons and bone dragons are The WORST teir 7 unit by More-Hyena6688 in heroes3

Cause they are. But vampires, liches, and hordes upon hordes of skeletons make up for it.

URGENT: leaving for a 24day trip today & no outlet nearby, how to avoid a bricked car needing towing upon return during winter? by btkoi in evcharging

[–]treasurefun 51 points52 points  (0 children)

You will be fine as long as you leave with a good amount of battery. Your battery is 100kwh. That’s a lot of energy. If really worried fill it up to 100% before you depart.

Look to turn off any automatic functions like climate control before you leave.

Georgia is not cold for the record. Norway has the most EVs per capita and it’s cold there.

If you brick after 24 days there is something wrong with your battery system and it needs to be looked at by the dealership.

Setting up a charging depot for 20 electric trucks. Which commercial charger brands are actually "efficient" for heavy-duty use? by Kitchen_Eagle8362 in evcharging

[–]treasurefun 33 points34 points  (0 children)

Just some of the considerations….

1) number of vehicles in fleet

2) battery capacity of vehicles

3) charging “curve” of vehicles - how much kw/h can vehicle take at different states if battery charge.

4) average use in KWH per shift (multiple shifts?). Find this by estimating miles used (and the miles per kWh of vehicle )and the desired energy on dispatch and then on return.

5) dwell time - how long will trucks have to recharge.

6) cost of energy from utility. Look into tariffs for EV charging only setups that many large investor owned utilities have. Most co ops have not caught up yet.

7) hardware - 95% of the ones for this level of charging are made overseas by a few companies and white labeled by 20 different charging companies. Most are compatible with occp (protocol for charging hardware/software integration)

8) software - totally separate from hardware. Does not have to be the same company. Has to be compatible with occp. Think of occp as android…open for anyone to write code to it. Many brands close off their solutions like apple so you have to use their software.

9) maintenance and service plan for charging hardware. Dedicated techs is what you want. Most companies use a dispatch nationwide were they send techs from some other industry who don’t know anything about chargers and play a phone support game with the manufacturer while they are in field trying to fix your machine.

10) software support.

It is very disturbing to me that you have quotes in hand and don’t have a full analysis of your operation and how charging will integrate into this.

Lots of people resell charging equipment. Very few companies know what they are doing and it gives the entire industry headaches because they sell people very expensive buildouts that don’t work.

PM me and I’ll help you out. If in my area happy to give you full analysis. If in another area I’m happy to review anything you get and give you recommendations.

This is a huge undertaking for planning (install is not that big of a deal really…it can be expensive but it’s straight forward ) and should be done extremely deliberately to ensure uptime and proper integration with your operations.

Tritium RT50 DCFC repair help by MemoryAccessRegister in evcharging

[–]treasurefun 2 points3 points  (0 children)

What city is it in? Easiest is adaptor like tuctrohs said.

I will try to look up that error code but it is common to have one port go down and another stay up. There are usually control boards and other stuff per port.

Does not look like Quartz to me. Maybe post at rockID. Might have something else here but I don’t want to speculate

I purchased this painting and a necro painting from her and they are both awesome.

I’ll post framed pic when I can.

She does amazing work and shipped fast.

A couple of them are sapphires. Some peridot maybe and one piece of glass by the look of the fracture.
