Rivian Teams Up with WeaveGrid to Bring Smarter, Cheaper Charging to Your Driveway
Rivian just announced a new partnership with WeaveGrid that could make home charging smarter, cheaper, and better for the planet. Starting later this year, Rivian drivers will be able to opt into utility-managed charging programs through WeaveGrid, earning financial incentives just for charging at the right times.
The idea is simple: most EV charging, over 80% of it, happens at home. But energy prices (and grid stress) vary throughout the day. WeaveGrid works directly with utilities to shift EV charging to times when electricity is cheaper and often cleaner. With this new integration, Rivian drivers will be able to automatically charge when it makes the most sense, without having to think about it.
That means more money in your pocket, lower emissions, and a more stable grid. Everyone wins.
For Rivian, this is another move in their push toward building a fully connected, software-defined vehicle experience. Wassym Bensaid, Rivian’s Chief Software Officer, called the collaboration a perfect example of how smart EVs can play a bigger role in the energy ecosystem. “We’re helping customers save money while supporting the grid and cutting emissions,” he said.
A big part of why this works? Trust. Both Rivian and WeaveGrid emphasized that customer data is protected through secure, OEM-approved connections. Drivers stay in control of their charging preferences, like desired charge level and timing, and the system handles the rest in the background.
WeaveGrid’s CEO Apoorv Bhargava added that this partnership will help scale utility EV programs even faster, unlocking more real-time, grid-responsive charging across the U.S.
The integration will roll out later this year, giving Rivian owners another reason to plug in with confidence, and another reminder that smart software is becoming just as important as hardware in the EV world.
Maybe I’m missing something, but WeaveGrid is already available (at least in my market), and is independent of the car manufacturer. Since I already set my Rivian to only charge between midnight and 8 AM when my utility gives a discount, the only potential benefit should be charging based on predicted needs. However, since my daily commute is short but my twice a month on average commure is quite long, the predictions are never enough for the long commute and I have to manually choose to start charging earlier. The other issue is having more than one electric car that uses the same charger. My daughter’s Honda doesn’t play nice with WeaveGrid unless you completely disable the Honda’s scheduling features, and either way the predictive charging gets confused between our cars and needs. It seems the only benefit to this program is that it automatically schedules most charging in off peak hours, something that our Rivians and just about every other EV and charger can already do.
Supposedly there was a monetary incentive to sign up, but it’s been months and I’ve yet to see a cent. Smartcharge NY, on the other hand, sends me a nice little deposit every month, not to mention referral and other bonuses.
So the reason they are partnering with car companies is because not every charging station is able to feed the data regarding location (to make sure you’re charging at home) and charge amounts.
Rivian opening their API like Tesla did will allow for any Rivian owner to join the program/get the rebate regardless of what brand their level 2 charger is as WeaveGrid will connect right to the API/car itself.
I have solar so utility price based charging is not so useful for me. If they could set the charge rate based on the solar output, then it will be really useful. Right now I manually adjust the charge throughout the day, a bit of a pain but I want to stay off the grid as much as possible.
It’s the only benefit I have with Tesla, charge on solar. First brand that adopts that I can trade it in.
I think the point is being missed Weavegrid works with the utility to find the best time to charge. I think of it like this, I have about 10 EVs in my immediate neighborhood. If all them waited to charge when their rate drops, that could slam the network. Weavegrid helps to delay and space out when the cars start to charge. You can always override, but that is how I understand it.
Slam the network? Do you think we have grid issues when people run their dryers at the same time? I don’t think this is as much of the issue as you think it might be.
I don’t think the grid is getting slammed by 10 EV’s at midnight?
