With electric school buses rolling out across the US, new information suggests upgrading your district’s fleet may bring additional benefits beyond producing zero emissions, including higher attendance.

School buses pick up over 25 million children each year, traveling around 5.7 billion miles. Up until recently, many of these buses were diesel-powered.

Diesel exhaust has been shown to pose a severe danger to the kids riding the buses, drivers, staff, and communities they operate in, with over 40 toxic air contaminants, carcinogens, and other harmful fine particle matter.

Several studies have even suggested exposure to the pollutants can be up to 10 times higher inside the bus, especially while constantly idling to pick up students.

When exposed, diesel exhaust can cause serious health effects such as asthma, heart attacks, strokes, cancer, and even premature death.

To overcome this, the EPA has set aside funds to help school districts replace their fleets with cleaner alternatives. The EPA gave out over $7 million between 2012 and 2017 to upgrade districts’ fleets.

New study shows electric school buses improve attendance

According to a new study published in Nature Sustainability analyzing the EPA data shows replacing outdated diesel buses with electric or a cleaner alternative can result in significantly higher attendance.

The study estimates that over 350,000 additional student days of attendance were added in the school districts that won the EPA funding lottery.

Furthermore, the study found that there were six more students per day in attendance for every 10,000 students in the year after the lottery compared to districts that were not selected for funding.

Dr. Lisa Patel, a member of the American Academy of Pediatrics Council on Environmental Health and Climate Change, said:

I think everybody recognizes that those fumes make people sick. This study drew a really clear line between exposure to that pollution and the impact on children.

The findings from the study are consistent with other data showing cleaner or electric school buses can reduce lung inflammation in riders as well as lower communitywide hospitalizations due to bronchitis, asthma, and pneumonia in at-risk populations.

Researchers from the study estimate that replacing every school bus built before the year 2000 with an electric or cleaner option can add over 1.3 million attendance days in the US.

Electrek’s Take

The benefits of upgrading to electric school buses go beyond just reducing emissions. New findings continue to show electric school buses can protect students, bus drivers, staff, and the communities they work in.

The clean school bus program provides over $5 billion in funding from the recently passed Bipartisan Infrastructure Law to replace the nation’s fleet over the next five years.

Through the program, districts are eligible for up to $375,000 to replace old, outdated diesel buses with electric. Districts can also take advantage of $20,000 per vehicle for charging infrastructure. The administration rewarded 289 districts across the US with nearly $1 billion in October to replace over 3,400 clean school buses.

The new EPA emission rules introduced this week are expected to accelerate the transition to electric school buses further. The agency now expects 50% of “vocational vehicles,” including school buses, delivery trucks, dump trucks, and more, to be electric by 2032.

Saldivar’s Trucking: first owner-operator to deploy Volvo VNR Electric semi

Saldivar's Trucking: first owner-operator to deploy Volvo VNR Electric semi

Owner-operators are a huge part of the heavy truck market, and they’ve been among the most hesitant groups to transition from diesel to electric semi trucks. That may be changing, however, as Saldivar’s Trucking becomes first independent owner-operator in the US to deploy a Volvo VNR Electric Class 8 truck.

The higher up-front cost of electric semi trucks has been a huge obstacle for smaller fleets. That’s there are incentives from governments, utilities, and even non-profits to help overcome that initial obstacle. And the smart dealers are the ones who are putting in the hours to learn about those incentives, educate their customers, and ultimately sell more vehicles.

TEC Equipment is a smart dealer, and they worked closely with South Coast Air Quality Management District to secure the CARB funding and ensure Saldivar’s was able to ssecure $410,000 in funding from CARB’s On-Road Heavy-Duty Voucher Incentive Program (HVIP), which provides funding to replace older, heavy-duty trucks with zero-emission vehicles. The program is directed exclusively to small fleets with 10 vehicles or less that operate in California and aims to bridge the gap between the regulatory push for clean transportation and the financial realities faced by small business owners.

“TEC Equipment has been instrumental in supporting owner-operators like Saldivar’s Trucking through the transition to battery-electric vehicles,” explains Peter Voorhoeve, president of Volvo Trucks North America. “Their dedication to providing comprehensive support and securing necessary funding demonstrates how crucial dealer partners are in turning the vision of owning a battery-electric vehicle into a reality for fleets of all sizes.”

Saldivar’s Volvo VNR Electric features a six-battery configuration, with 565 kWh of storage capacity and a 250 kW charging capability. The zero-tailpipe emission truck can charge to 80% in 90 minutes to provide a range of up to 275 miles.

Those specs mean the Volvo electric semi is more than capable of meeting Saldivar’s operational needs, which include night shifts at California ports covering 175-200 miles per night, five nights a week. And, as he adds his VNR Electric miles to Volvo’s ever-growing tally, other owner-operators will see that it works for them, too.

“While large fleets often make headlines for their ambitious investments in battery-electric vehicles, nearly half of the 3.5 million professional truck drivers in the U.S. are owner-operators running their businesses with just one truck,” adds Voorhoeve. “These small operations face unique challenges, from the initial capital investment to securing adequate charging infrastructure … this collaboration is a perfect example of the important role to be played by truck dealers and why stakeholders need to work together to succeed in this new era of sustainable transportation.” We need solutions that work for different fleets of all sizes in the marketplace,” added Voorhoeve.”

Electrek’s Take

Electrifying America’s commercial trucking fleet can’t happen soon enough – for the health of the people who live and work near these vehicles, the health of the planet they drive on, and (thanks to their substantially lower operating costs) the health of the businesses that deploy them. TEC is doing a great job advancing the cause, and acting as true expert partners for their customers.

Mercedes’ upcoming electric CLA has a ton of neat EV tech and options

Mercedes' upcoming electric CLA has a ton of neat EV tech and options

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.

Insight Drivetrains & Efficiency Test Bench Sindelfingen 2024

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.

Reyes Beverage Group adds 29 Freightliner electric semi trucks to California fleet

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.

Electrek’s Take

Food and beverage trucks operate everywhere – not just at the ports but in urban population centers, too. That means they’re pumping out harmful emissions right where a lot of people live and work, and that’s no bueno, making the electrification of these vehicles a no brainer for anyone who cares about the quality of life of the people who live and work near them.
