Charging While Driving Now Possible In Michigan

December 14, 2023 by 66 Comments

Heavy vehicles like semi trucks pose a bigger challenge in electrifying the transportation fleet than smaller, more aerodynamic passenger cars. Michigan now has the first public in-road charging system in the United States to help alleviate this concern. [via Electrek]

Electreon, a company already active in Europe, won the contract to provide for the inductive coil-based charging system at the new Michigan Central Station research campus. Initial runs will be with a Ford E-Transit for testing, but there are plans to actually allow public use along the one mile (1.6 km) route in the near future.

Vehicles using the system need a special receiver, so we hope we’ll be seeing an open standard develop instead of having to have a different receiver for each road you drive on. This seems like it would be a more onerous swap than having to have three different toll road transponders. Unfortunately, the page about wireless standards on the Electreon website currently 404s, but CharIN, the standards body behind the Combined Charging Standard (CCS) did just launch a task force for wireless power delivery in September.

If you’re curious about other efforts at on-road charging, check out this slot car system in Sweden or another using pantographs.

What Happened To Sweden’s Slot Car EV Road?

Many EVs can charge 80% of their battery in a matter of minutes, but for some applications range anxiety and charge time are still a concern. One possible solution is an embedded electrical rail in the road like the [eRoadArlanda] that Sweden unveiled in 2016.

Overhead electrical wires like those used in trolleys have been around since the 1800s, and there have been some tests with inductive coils in the roadway, but the 2 km [eRoadArlanda] takes the concept of the slot car to the next level. The top of the rail is grounded while the live conductor is kept well underground beneath the two parallel slots. Power is only delivered when a vehicle passes over the rail with a retractable contactor, reducing danger for pedestrians, animals, and other vehicles.

One of the big advantages of this technology being in the road bed is that both passenger and commercial vehicles could use it unlike an overhead wire system that would require some seriously tall pantographs for your family car. Testing over several Swedish winters shows that the system can shed snow and ice as well as rain and other road debris.

Unfortunately, the project’s website has gone dark, and the project manager didn’t respond when we reached out for comment. If there are any readers in Sweden with an update, let us know in the comments!

We’ve covered both overhead wire and embedded inductive coil power systems here before if you’re interested in EV driving with (virtually) unlimited range.

Hyundai To Lead US Market For Hydrogen Fuel Cell Trucks

December 13, 2022 by 96 Comments

Hydrogen has long been touted as a potential fuel of the future. While it’s failed to catch on in cars as batteries have taken a strong lead, it still holds great promise for larger vehicles like trucks.

Hyundai have been working diligently in this space over the last few years, with its Xcient line of fuel-cell powered trucks. It’s set to dominate the world of hydrogen trucking in the US as it brings a fleet of vehicles to California next year.

Trucks Could Soon Run On Electrified Highways

July 18, 2022 by 180 Comments

Electric vehicles make for cleaner transport. However, they’re hung up by the limited range available from batteries. Long recharge times further compound the issue.

These issues are exacerbated when it comes to trucks hauling heavy goods. More payload means more weight, which means less range, or more batteries, which means less payload. Electric highways promise to solve this issue with the magic of overhead wires.

Hyundai Makes Push Towards Fuel Cell Trucking

July 16, 2020 by 102 Comments

Hyundai has begun shipping fuel-cell based heavy duty trucks to face off against battery-electric trucks in the commercial hauling market.

Battery electric vehicles, more commonly known as electric cars, have finally begun to take on the world in real numbers. However, they’re not the only game in town when it comes to green transportation. Fuel cells that use tanks of hydrogen to generate electricity with H2O as the main byproduct have long promised to take the pollution out of getting around, without the frustrating charge times. Thus far though, they’ve failed to make a major impact. Hyundai still think there’s value in the idea, however, and have developed their XCIENT Fuel Cell truck to further the cause.

Ask Hackaday: Does Your Car Need An Internet Killswitch?

October 1, 2019 by 103 Comments

Back in the good old days of carburetors and distributors, the game was all about busting door locks and hotwiring the ignition to boost a car. Technology rose up to combat this, you may remember the immobilizer systems that added a chip to the ignition key without which the vehicle could not be started. But alongside antitheft security advances, modern vehicles gained an array of electronic controls covering everything from the entertainment system to steering and brakes. Combine this with Bluetooth, WiFi, and cellular connectivity — it’s unlikely you can purchase a vehicle today without at least one of these built in — and the attack surface has grown far beyond the physical bounds of bumpers and crumple zones surrounding the driver.

Cyberattackers can now compromise vehicles from the comfort of their own homes. This can range from the mundane, like reading location data from the navigation system to more nefarious exploits capable of putting motorists at risk. It raises the question — what can be done to protect these vehicles from unscrupulous types? How can we give the user ultimate control over who has access to the data network that snakes throughout their vehicle? One possible solution I’m looking at today is the addition of internet killswitches.

Printed Parts Make DIY Electric Longboard Possible

November 4, 2017 by 13 Comments

Appalled by expensive electric longboards, [Conor Patrick] still wanted one, and wanted it now. So — naturally — he converted an existing board into a sprightly electric version at a fraction of the cost.

[Patrick] is using a capable 380KV Propdrive motor, capable of pushing him up to 30mp/h! A waterproof 120A speed controller and 6000mAh, 22.2V LiPo battery slim enough to fit under the board give the motor the needed juice. He ended up buying the cheapest RF receiver and remote combo to control the board, but it fit the all-important “want electric long board now” criterion.
