Quick Question - does the upcoming Tesla API charges affect charge-control of Tesla cars, reading of power data from Tesla Powerwall batteries, or both?
I charge a non-Tesla car through a OCPP-controlled charger, with CHQ reading the power-flow from a Tesla PW2 for the solar/grid/home/battery sensors.
If Tesla are going to be charging a significant fee for access to the car-charging API, sounds like a surcharge for Tesla car accounts might be the most transparent cost-recovery option around. Tesla drivers $7/month, non-Tesla drivers $3/month. Sorted.
Hi Adam et al,
OVO has now informed me like many others (I am a bit behind in my emails having been away) that my EV Plan has changed, everything gone up except the FIT that has gone down from 8c/kWh to 3c/kWh. The exception being that if I join EV Control they will leave me on the 8c tariff!!
This amounts to quite a $ amt per month to do this of course.
I know I maybe asking the wrong people here, but I have been with Charge HQ for a while, now paying the Solar Plan, but will OVOās EV Control give me the same benefits as Charge HQ?
It appears, if I swap over to EV Control and change to the Charge HQ free plan, I earn the extra FIT $'s and save paying for the Solar Plan?
Even though I cannot see a reason to run both, are there any issues with running both? If I switch off Charge HQ, would that solve any issues, or just as importantly, if I turn off EV Control after I join will OVO know anyway?
Are there any other complications?
My apologies for such a convoluted email. Just trying to see a way forward in all of this
You either let your electricity retailer to control your charging, or you control it yourself according to your excess solar / scheduling.
They way OVO controls the charging will be purely based on the wholesale pricing they are being charged at the time, with the priority set to your time of departure.
It is a different way to charge your car. I suggest jumping online and looking at some reviews of electricity retailers that are currently offering the same thing with EV control, and then decide for yourself which approach is more suitable for you.
For me, I want the control, and my solar system is not massive. It makes more sense for me to stick with the OVO EV plan and use Charge HQ to control all my charging.
This would be great if it became an option. Thereās very few all-in-one Raspberry Pi OCPP solutions out there (and none of them are anywhere near the quality and convenience that Charge HQ provides.)
Iām a paid subscriber to Charge HQ & am with OVO in Australia. I just had a play with with the OVO EV Control. As expected, it was pretty lame & I deleted itās access to my Tesla within about 5 minutes of granting access. Charge HQ is great & I wish the devs all the best
Bad news about awful Tesla (smacks of the same Apple bs).
In any case OCPP chargers are brilliant, nor do we need faffing about with so-called āsolar awareā & overpriced EV chargers than rarely do that well, can haved botched installs, wrong CT clamp locations etc.
Forgetting about Tesla, hereās hoping some the real Big EV sales an owners like BYD, get that togther, eg, a cheap Beny & Charge HQ.
For me, a Mach-E & a Wallbox pulsar has been perfect for ChargeHQ.
I am new to this and HQ but from my experience with Power companies and lack of useful information, I can only say I rather pay $5 per month to a company that tries to safe me a few dollars than to a power company.
For example, I was monitoring my power consumption which my provider gives my in 30 minutes intervals. I was curious about the fact that I was supplying to the grid and consuming at the same time and found that rather intriguing.
The answer was that my hot water system is on a controlled load and that is a separate meter that does not use the solar energy I generate. The result is that I pay $0.30 for several KWh that in fact I sell them for $0.04. What a ripp off.
The solution is to disconnect the hot water from the controlled load and use solar to charge it. That is where Charge HQ could really come in and save me $50 per month with a solution
