Tesla has launched its “next-gen Megapack controls platform,” which it claims enables faster deployment and commissioning of large-scale energy storage systems than its competitors.
Megapack has become the go-to battery system for electric utilities looking to deploy large-scale energy storage, whether to stabilize the grid or take better advantage of renewable energy.
The battery system has become popular due to its cost, ease of deployment, and availability at scale, but these attributes are not solely due to Tesla’s expertise in building battery pack hardware. In fact, we have previously reported on Megapack customers taking advantage of Tesla’s software platforms for energy storage, like Autobidder and Powerhub.
Now we learn that Tesla is deploying a new ‘Megapack controls platform,’ which one engineer frames as a difference-maker, enabling meaningful savings for customers. Chris Bowman, senior staff product manager at Tesla in charge of software and firmware for battery energy storage platforms, shared on LinkedIn:
Our next gen. Megapack controls platform, combined with our industry-leading controller-hardware-in-the-loop test services (our “CHIL” platform), speeds up and de-risks deployment of Gigawatt scale battery and hybrid renewable plants. This matters because time and time again, our competitors fail on control system commissioning, causing multi-million dollar losses and 3-4 month project delays.
In short, the Tesla engineer claims that the platform enables quicker and smoother deployment and commissioning, which is important since those large-scale projects are often worth north of $100 million, and delaying turning on the batteries can result in critical losses.
Bowman continues with even harsher comments on Tesla’s energy storage competitors, claiming that the companies are deploying “un-tested” controls:
Un-like our competitors, who deploy bespoke and un-tested RTAC controls, Tesla’s innovative control system engineers productize regionally specific Control Templates (e.g. North America, Australia, etc.) that are CHIL-tested and approved. Our approach provides EPCs with turnkey control solutions that work the first time; and, meet the needs driven by electrical topology of large plants, the interconnection type, and regulations.
When the two factories are online and fully ramped up, they will produce 80 GWh of Megapacks per year – more than ten times Tesla’s overall energy storage capacity deployed in 2022. In the meantime, Tesla currently has a two-year backlog of orders for the Megapack.

Mercedes released a look at the powertrain technology of its upcoming electric CLA, and it includes tons of neat EV tech and some interesting options for battery technology and what looks to be the most flexible charging system we’ve seen yet.
We’ve already learned a fair amount about the CLA after first seeing the concept last year, and Mercedes released a few new specifics today regarding its powertrain.
In keeping with previous information we knew, the CLA is targeting extremely high efficiency of 12kWh/100km, which translates to just 193Wh/mi or 5.2mi/kWh. That’s more efficient than anything else on the road today – with Lucid’s Air Pure reaching 200Wh/mi, or 5mi/kWh. And just less than what Tesla is claiming the Cybercab will be capable of, at 5.5kWh/mi.
This is thanks to Mercedes’ new compact EDU 2.0 electric motor, which is part of its new Mercedes Modular Architecture (MMA) which will underpin its upcoming electric vehicles. The drive motor will be 200kW on the rear axle, though all-wheel drive models will be available with an additional 80kW unit on the front axle. A two-speed transmission will ensure efficiency at high speeds and low.
For more efficiency in cold weather, the CLA will use an air-to-air heat pump which is able to capture heat from the motor, battery, and ambient air to heat the cabin. While batteries and motors don’t make nearly as much waste heat as inefficient ICE engines, it’s still good to be able to channel heat to wherever you need it.
Mercedes says that the CLA will come equipped with a choice of two different batteries, each with different chemistries.
The larger 85kWh model will be capable of an unnecessarily-high 750km (466mi) of WLTP range – though WLTP numbers are always higher than EPA numbers, so expect something in the high-300s in EPA parlance. This battery will add silicon oxide to the anode for higher energy density, a technology that has been pioneered by Sila Nanotechnologies, a company which Mercedes is a lead investor in.
The smaller battery will be 58kWh, and will use lithium iron phosphate (LFP) chemistry. LFP is a cheaper but lower energy density technology, with higher long-term durability and simpler sourcing of minerals (it uses no cobalt, whereas Mercedes says cobalt has been “reduced” in the larger batteries). However, LFP generally has slower fast charging and cold weather performance.
On charging: the “premium” battery will have an 800V configuration capable of up to 320kW charging speeds. Mercedes says this can add 300km (186mi) of range in 10 minutes, and also says that the car will have a broad charging curve, which means you’ll get high charge rates even if the battery isn’t close to empty. It didn’t specify if the smaller LFP battery will have the same charge rate.
This high charging rate allowed Mercedes to set a record traveling 3,717km (2,309mi) in 24 hours at the Nardo test track in Italy in a pre-production CLA. That’s an average travel rate of 96mph – including time spent charging.
We also learned something about Mercedes’ NACS adoption plans. While just about everyone has committed to transitioning cars to NACS, it has taken longer than expected (largely due to Tesla’s chaotic CEO firing the whole supercharger team for little reason), and few cars have native NACS inlets yet. Some brands can already charge at Superchargers with adapters, but Mercedes is still on Tesla’s “coming soon” page.
As a result of delays in onbaording automakers, some seem to have pulled back on their plans, pushing NACS ports to later model years. But Mercedes has a new and unique solution – it will just put both CCS and NACS ports on the CLA, right on top of each other.
Mercedes says “in the future, new entry-level models will be capable of bidirectional charging,” but isn’t clear whether this model will be capable of that.
Electrek’s Take
While this is short of a full release of specs, we’re excited by what we see here. Mercedes seems to confirm that they’re meeting the efficiency goals they set out, and we like that they’re offering a variety of options and taking advantage of some newer EV tech like 800V charging infrastructure.
The inclusion of both NACS and CCS is very interesting, again offering options to owners during the transition. That seems to be the big message from Mercedes here – we’re not going to just pick one tool, we’re going to use all of them.
But pricing and availability are obviously big questions, as is design.
The concept looks fantastic, but concepts always change on their way into production. The shape of the camouflaged test vehicle is very different – but looks to have some shrouding on the front and back to hide its shape, so we’ll have to wait until we see this thing unveiled for more.
And as for pricing – Mercedes says the CLA will be an “entry-level” car, but who knows what that means anymore these days. The base ICE CLA starts at around $44k currently, so lets see if they can hit that number.

Daimler Truck North America has helped alcohol distributor Reyes Beverage Group deploy fully 29 zero-emission Freightliner eCascadia Class 8 electric semi trucks in its California delivery fleet.
Reyes Beverage Group (RGB) plans to deploy the first twenty Freightliner electric semi trucks at its Golden Brands – East Bay and Harbor Distributing – Huntington Beach warehouses, marking the first phase in the company’s transition to a fully zero emission truck fleet by 2039. An additional nine eCascadia Class 8 HDEVs are scheduled for delivery to RBG’s Gate City Beverage – San Bernardino warehouse before the end of 2024.
RBG’s decision to adopt the Freightliner eCascadia builds on its recent transition to renewable diesel and its ongoing idle-time reduction program. These electric vehicles (EVs) “go electric” will contribute significantly toward the company’s stated goal of reducing its carbon emissions 60 percent by 2030. These 2 trucks will save some 98,000 gallons of diesel fuel annually, and avoid putting nearly 700 metric tons of carbon dioxide and other harmful emissions into California’s air each year.
“We are excited to be among the first in our industry to adopt these electric vehicles,” explains Tom Reyes, President of RBG West. “This is a significant step toward our sustainability goals and ensuring compliance with state regulation as we transition our fleet to EV.”
Freightliner’s eCascadia electric semi trucks offer a number of battery and drive axle configurations with ranges between 155 and 230 miles, depending on the truck specification, to perfectly match customers’ needs without compromising on performance and load capacity. RBG’s Freightliner eCascadia tractors will rely on electric charging stations installed at each facility, allowing them to recharge to 80% capacity in as little as 90 minutes for RGB’s trucks, which feature a typical driving range of 220 miles as equipped.
The Windsor, Ontario utility says it’s driving towards a more sustainable future after adding a dozen new electric vehicles to its fleet – including a state-of-the-art, 55-foot Terex electric bucket truck.
Based on a Class 7 (33,000 lb. GVWR) International eMV Series BEV, the Terex EV takes the eMV’s 291 kWh battery and adds the Terex Optima 55-foot aerial device and HyPower SmartPTO system to create a fully electrified utility service vehicle that can do anything its diesel counterparts can do while offering better, safer working conditions for utility crews.
“We’ve got 12 EVs,” said Gary Rossi, president and CEO, Enwin Utilities. That number represents fully 10% of the utility’s entire vehicle fleet. “Our centerpiece is our electric 55-feet bucket truck. It’s very quiet,” continues Rossi. “So (the truck) allows us, our crews, to communicate better. It’s not as loud in the community when they’re doing repairs in someone’s backyard.”
That notion is echoed by Terex, itself. The company says its HyPower SmartPTO (power take off), which replaces a mechanical PTO, avoids a loud idling engine while reducing workers’ exposure to toxic exhaust fumes.
“It’s all about building Windsor’s future and literally plugging into the battery factory down the road that is being constructed and showing that Windsor is a leader on this front,” says Drew Dilkens, Mayor of Windsor. “I don’t own an internal combustion engine vehicle,” adds Mayor Wilkins. “I only own two electric cars. My wife and I, we made the change starting in 2019 and I can’t see myself ever going back.”

Enwin says its commitment to clean energy extends beyond its vehicle fleet. The company recently unveiled a massive MW solar rooftop net metering facility at its Rhodes Drive headquarters with over 3,000 solar panels. The site, one of Canada’s largest solar installations, generates enough clean electricity to power 300 homes annually.
