Competition to provide the best energy savings to EV owners is heating up between auto makers.

General Motor’s unit GM Energy has just released PowerBank, a stationary energy storage battery pack that gives electric vehicles (EV) owners the ability to store and transfer energy from the electric grid, and allows integration with home solar power equipment.

The PowerBank, which comes in 10.6kWh and 17.7kWh battery capacity variants, can power up a home when there is an outage or help offset higher electricity rates during peak demand, GM said. In addition, customers can also use PowerBank to store and use solar energy, supplement the charging of EVs and provide power to a home without an EV being present.

GM says that combining two of its 17.7kWh PowerBanks can provide enough energy to power the average American home for up to 20 hours.

The PowerBank can be bought as part of two bundles: the GM Energy Storage bundle at $10,999, or the GM Energy Home System bundle at $12,700. The latter includes a bi-directional EV charger that can provide up to 19.2kWh of power.

By comparison, Tesla’s energy storage system, PowerWall 3, can store 13.5kWh of energy and has a price tag of $9,300.

According to GM Vice President Wade Sheffer, one key advantage of the PowerBank it its “modularity,” which allows for easy integration with existing technology.

GM announced in August that it would provide vehicle-to-home (V2H) technology on all its model year 2026 models. It will now also offer vehicle-to-grid (V2G) technology, which can provide additional energy and financial savings.

Energy savings coming from the integration of electric vehicles, solar-powered homes, and energy grids are increasingly at the center of EV manufacturers’ offerings.

Nissan, BMW, Ford, and Honda have grouped together to offer the ChargeScape V2G software, which connects EVs to utilities and the power grid. EV owners can receive financial incentives to pause charging during peak demand or sell energy back to the grid.

While Tesla has so far backed off from embracing V2G technology, CEO Elon Musk has hinted that V2G tech could be introduced for Tesla vehicles in 2025.

Robotaxi aside, a $25,000 EV would be pointless, Tesla CEO says

Enthusiasts expecting to one day put their hands on the steering wheel of a $25,000 Tesla EV may feel like they’ve been taken for a ride.
CEO Elon Musk has just put a serious damper on those expectations, saying that outside of the driverless Robotaxi recently unveiled by Tesla, a regular $25,000 model would be “pointless” and “silly.”
During a conference call with investors, Musk was asked to clarify whether such a model was in the works.
"Basically, having a regular $25K model is pointless,” Musk said. “It would be silly. It would be completely at odds with what we believe." Tesla, Musk continued, has “been very clear that the future is autonomous.”
On October 10, Tesla unveiled its much-awaited robotaxi, called the Cybercab, an autonomous-driving EV with no steering wheel or pedals. The company also unveiled the Robovan, a much larger autonomous vehicle expected to carry people or goods.
The automaker said the Cybercab is expected to be produced in 2026 and cost $30,000. Musk, meanwhile, said that it would be a $25,000 car without specifying if that price tag included federal tax credits.
Tesla’s ambiguity about an affordable entry-level model has been going on for years. In 2020, Musk signaled that a $25,000 Tesla would arrive within three years. It was later reported that Tesla had ditched the idea, instead favoring the development of a robotaxi.
Language within Tesla’s latest financial report still hints that new affordable Tesla models are on the way. But Musk’s latest comments are putting a floor on just how affordable these would be. So far, Tesla’s Model 3 Rear-Wheel-Drive remains the company’s cheapest model, with a base price of $38,990.
Some rival EV makers, meanwhile, are entering the affordable space more aggressively in the U.S.
General Motors has already put out its Chevy Equinox EV at a price of $27,500, including federal tax credits. Volkswagen America says it plans to release an under-$35,000 EV in the U.S. by 2027.

Stellantis’ 2027 Dodge Charger Daytona might feature solid-state battery tech

The battle to use cheaper, more efficient, and safer EV batteries is heating up among automakers. At the heart of this battle, the development of solid-state battery technology, an alternative to highly flammable and costly lithium batteries, is garnering more and more attention.For proof, Stellantis, the world’s fourth-largest automaker, is betting on the technology for its next generation of electric vehicles. The Netherlands-based company announced that it will launch a demonstration fleet of Dodge Charger Daytona EVs that will feature solid-state battery tech made by U.S. startup Factorial.The demo fleet, expected to launch by 2026, will provide a real-world assessment of Factorial’s technology. Factorial has been partnering with Stellantis since 2021 and is also partnering with the likes of Daimler AG’s Mercedes-Benz and Hyundai.Besides Dodge, the technology would eventually be deployed on the Stellantis STLA Large multi-energy platform, which includes brands such as Jeep, Chrysler, Alfa Romeo, and Maserati.Stellantis said that the integration of solid-state battery technology will yield “improved performance, longer driving ranges, and faster charging times in the coming years.”Factorial, meanwhile, says its technology provides higher energy density, reduced weight, improved performance, and the potential for further reduction in total vehicle cost over time. Stellantis, Daimler, and Hyundai aren’t the only ones to bet on solid-state battery tech. Toyota, the largest automaker in the world, has heavily invested in the technology. It also created a coalition with Nissan and Panasonic to boost its production in Japan. So far, making solid-state batteries has remained an expensive endeavor. But steps such as the Stellantis demo fleet and production at scale by the likes of Factorial are expected to improve manufacturing processes and costs over time.Other automakers, meanwhile, are working on ways to improve lithium batteries. Volkswagen, for one, is developing its own unified battery cell in several European plants as well as one plant in Ontario, Canada.

Costco partners with Electric Era to bring back EV charging in the U.S.
costco ev charging us electricera fast station 1260x945

Costco, known for its discount gas stations, has left EV drivers in need of juicing up out in the cold for the past 12 years. But that seems about to change now that the big-box retailer is putting its brand name on a DC fast-charging station in Ridgefield, Washington.
After being one of the early pioneers of EV charging in the 1990s, Costco abandoned the offering in 2012 in the U.S.
While opening just one station may seem like a timid move, the speed at which the station was installed -- just seven weeks -- could indicate big plans going forward.
Besides lightening-speed installation, Electric Era, the Seattle-based company making and installing the charging station, promises to offer “hyper-reliable, battery-backed fast charging technology in grid-constrained locations.”
Its stalls can deliver up to 200 kilowatts and come with built-in battery storage, allowing for lower electricity rates and the ability to remain operational even when power grids go down.
If that sounds like it could very well rival Tesla’s SuperCharger network, it’s no coincidence: Quincy Lee, its CEO, is a former SpaceX engineer.
Costco also seems confident enough in the company to have put its brand name on the EV-charging station. Last year, the wholesaler did open a pilot station in Denver, this time partnering with Electrify America, the largest charging network in the U.S. However, Costco did not put its brand name on it.
In an interview with Green Car Reports, Electric Era said it was still in talks with Costco about the opening of new locations. Last year, Costco said it was planning to install fast chargers at 20 locations, without providing further details. It has maintained EV-charging operations in Canada, the UK, Spain, and South Korea.
Meanwhile, the wholesaler’s U.S. EV-charging plans might very well resemble those of rival Walmart, which last year announced it was building its own EV fast-charging network in addition to the arrangements it already had with Electrify America.
