Cadillac Escalade IQ on Out of Spec’s “Eastern Edge”: An Epic Fail or Punt?

From News Coulomb. While watching @OutofSpecMotoring Eastern Edge ( https://youtu.be/RfcTgnxDuHA?si=qzesaBO7kdB9-19s ), I was surprised to see that Team Cadillac Escalade IQ wasn’t using battery preconditioning during the race because they had been told that it only warms but does not cool the battery. Given the results of the race, I’m sad that the Cadillac Escalade…

On the First Day of Boltmas… Present

From News Coulomb. It’s a Boltmas miracle! Boltmas is back, and this time, it is more present than ever. This year, I will endeavor to visit a number of charging sites in my region to showcase the current state of the public charging infrastructure. These trips will focus on smaller charging providers and equipment and…

Overcoming Challenges to Charging an EV Off-Grid

From News Coulomb. I’ve tried a number of different methods of charging an EV off-grid, and I’ve found that there’s really only one option. Standard pure sine inverters and solar generators mostly have improperly grounded AC outlets, and even the Anker f3800, which has an option for an internal neutral-ground bond for charging EVs, is…

Running PV Solar Panels in Parallel Can Be Dangerous

From News Coulomb. I’m intending for this video to be more of a PSA because it’s not information that was readily promoted when I was putting together some of my DIY solar arrays, but I think it’s extremely important for the community to know. Reiterating this type of information is good, and can prevent novices…

Is XT60 Current Rating Legitimate?

From News Coulomb. I’ve been walking through my DIY solar system, correcting issue and upgrading components. I recently upgraded the input power to my Anker Solix f3800, which is now being fed by 27 A of current from solar panels. Typically, a constant current of 27 A would require at least 10 AWG cables, so…

Don’t Take EV Carpool HOV Access Away

From News Coulomb. As of December 2025, electric vehicles and plug-in hybrids no longer have access to the high occupancy vehicle (HOV) carpool lanes. Rather than eliminating access for these clean air vehicles, we should abolish carpool lanes entirely, and if they are preserved as special access lanes, they should be restricted buses and other…

Plug-Side Chat: Are We Building Too Many Battery Factories?

From News Coulomb. In a recent story, InsideEVs covered the topic of how we might have overbuilt battery production facilities. According to a report from AlixPartners, our battery production capacity now far exceeds current EV demand. In my opinion, this is short-sighted. Even with a 2:1 production to demand ratio, that means that our current…
