Lightyear Solar EV Goes 441 Miles
Lightyear, the solar electric vehicle pioneer, has achieved a major technology performance milestone by driving 441 miles (710 km) of range with its Lightyear One prototype car. Never before has an electric vehicle driven such a long-range on a relatively small battery.
“After four years of hard work and in-house development, this is a very important engineering and technological milestone. It validates the performance of our patented technology and truly shows that we are able to deliver on our promise to introduce the most efficient electric vehicle. This prototype has over 440 miles of range with an energy consumption of only 137 Wh/Mile at 53 miles an hour. Even the most efficient electric cars in the market today consume around 50% more energy at this relatively low speed”, says Lex Hoefsloot, CEO and co-founder of Lightyear. “This milestone is a great confirmation of the scalability of our business model. We are confident that in the coming months, we will be able to reach a similar level of energy consumption at highway speed. Lowering the energy consumption per mile of an EV means that you can provide a lot of range on a small battery. Because batteries are the most expensive part of an EV, you can lower the purchase price of the car and achieve affordable electric cars with a lot of range that don’t need a lot of charging. Low-energy consuming cars can also benefit a lot more from adding solar cells to the car and gain about 45 miles of charge on a sunny day.”
The prototype car was put to the test at the Aldenhoven Testing Center in Germany, to complete a drive cycle at a speed of 53 miles per hour on a single battery charge of 60 kWh. The integral test ranged from validating the yield of the solar panels, the battery performance, the energy consumption of the cooling system, all the way to the functioning of the in-wheel motors and the software operating the solar car.
The conducted full drive cycle test is a crucial step to verify and validate all the assumptions of the vehicle’s performance. Beyond the validation of the technical performance of the car, other upcoming tests are related to the homologation process such as the crash tests and an official WLTP drive cycle test.
Lightyear is on a mission to make clean mobility available to everyone, everywhere and is gearing up for the industrialisation and manufacturing of Lightyear One. The concept of a long-range solar car represents a huge opportunity to change mobility, so you can drive for months without charging. An exclusive series of 946 Lightyear One’s will go into production in the first half of 2022. Lightyear wants to address the mass market starting from 2024.
Bosch Intros AVT for EVs
The electromobility business is booming. Certain applications, however, still pose enormous challenges for the electrical powertrain: when towing trailers, tackling steep ascents with a heavy load on board, or driving longer freeway stretches at high speed, the battery charge drops rapidly. Almost all electric cars have only one forward gear, but in such situations a multi-stage transmission can work more efficiently. To demonstrate this, Bosch installed a continuously variable automatic transmission (CVT) with push belt in a test vehicle. Called CVT4EV, this transmission increases efficiency by up to 4 percent. Depending on design, this can provide more torque in traction mode, better acceleration, or a higher maximum speed.
“The CVT4EV expands the electrical car’s repertoire,” says Gert-Jan van Spijk, who is in charge of CVT engineering at Bosch. And because the transmission adjusts the ratio continuously without loss of traction, the driving ease typical of e vehicles is not lost. Bosch contributes its systems expertise plus several components to the complete CVT solutions offered by specialized transmission manufacturers.
Better performance, lower energy consumption
The CVT4EV’s variable gear ratio provides the best possible balance of efficiency and performance. To this end, the system can freely control the speed and torque of the electric motor. At low speeds, a smaller gear ratio improves acceleration and handling characteristics on ascents, while a higher ratio enhances efficiency at higher speeds, as well as increasing top speed. In addition, it provides increased torque when towing and driving off-road, yet with lower energy consumption. Especially at constant speeds, the CVT4EV reduces the vehicle’s energy requirements.
Due to the electric motor’s reduced torque and speed requirements, a cheaper and more compact motor can deliver the same or even better performance. Alternatively, the same motor can achieve a greater range. As a result, manufacturers of electric vehicles can find the optimum balance between battery capacity and range.
High versatility, low complexity, reduced costs
This powertrain solution consists of a CVT4EV module, an inverter, an electric motor, and an axle drive with a ratio adapted to the vehicle. It is suitable for a wide variety of applications, from mid-size cars to sports cars to light commercial vehicles. Since individual software programs can often adapt the powertrains to the respective area of application, fewer hardware variants are needed. This cuts costs in both development and production. The use of CVT4EV also enables different driving modes for different types of vehicles, so carmakers can stand out from the competition by offering their brand’s typical handling in all their vehicle segments. As a result, end users get the driving experience they associate with the respective marque.
Compared to alternative variable solutions for electric vehicles, the CVT4EV offers a greater increase in the torque and engine speed available to the wheels. It also ensures completely smooth shifting without jolts – a must for electric vehicles. In addition, the larger spread of the CVT reduces the speed of the electric motor, resulting in an even smoother and quieter ride.
The concept of the CVT4EV with numerous Bosch components comes from Bosch Transmission Technology B.V., a Dutch subsidiary of Bosch. Based in Tilburg, the company is a leader in the development and mass production of CVT push belts. Full CVT4EV solutions are available through specialized transmission suppliers.

LED Demand Increases
Value demand for Light Emitting Diodes (LEDs) alone in automotive lighting will nearly triple from $1.4 billion in 2020 to $3.9 billion by 2024. The latest report “Automotive Lighting: Who Can Challenge LED’s Dominance?” from the Strategy Analytics Powertrain, Body, Safety & Chassis Service (PBCS) service, predicts that OEM requirements for styling and functionality will further increase demand for LED-based automotive lighting systems.
LED has seen further developments in efficiency and Tier 1 vendors have developed cost effective solutions for LED headlight modules. With the urgency to improve efficiency to support emissions and fuel economy mandates, the transition from halogen and xenon to LED has increased. But automakers are increasingly looking at styling with LED-based systems to win customers over their rivals. LED is also being used to raise functionality in lighting systems, particularly Digital Light Projection (DLP) and matrix LED headlights to form a precise Adaptive Driving Beam (ADB) and increase the use of glare-free high beam illumination, as well as new welcome lighting and even projecting messages and virtual lane markings.

Stellantis Reveals EV Roadmap
The Stellantis electrification roadmap encompasses the entire value chain. The company’s EV battery sourcing strategy is to secure more than 130 gigawatt hours (GWh) of capacity by 2025 and more than 260 GWh by 2030. The EV battery and component needs will be met with a total of five “gigafactories” in Europe and North America, completed with additional supply contracts and partnerships to support total demand.
Stellantis has signed memorandums of understanding (MOUs) with two lithium geothermal brine process partners in North America and Europe to ensure a sustainable supply of lithium, identified as the most critical battery raw material with regard to availability, as well as have the ability to integrate lithium into the supply chain once available.
In addition to sourcing strategies, Stellantis’ technical expertise and manufacturing synergies will drive battery costs lower. Electric vehicle battery pack costs are targeted to be reduced by more than 40% from 2020 to 2024 and by more than an additional 20% by 2030. All aspects of the battery pack play a role in reducing the costs – optimizing the overall pack, simplifying the format of the modules, increasing the size of the battery cells and upgrading the battery chemistry.
The company intends to maximize the full value of the battery life cycle through repair, remanufacturing, second-life use and recycling, as well as ensure a sustainable system that prioritizes customer needs and environmental concerns.
Affordability is a priority at Stellantis, as the company is targeting for the total cost of ownership of EVs to be equivalent to internal combustion engine vehicles by 2026.

Nuvve Enables V2G for School Districts
Nuvve Holding Corp. a global technology leader accelerating the electrification of transportation through its proprietary vehicle-to-grid (V2G) platform, announced today that it has been selected as the energy technology provider that will enable school districts and utilities in San Diego, Calif. and Durango, Colo. to accelerate the electrification of their school buses, further expanding Nuvve’s growing V2G network. Reinforcing its leadership in this market, Nuvve’s proprietary V2G technology will create value for the customers of these deployments by lowering the total cost of ownership of electric school buses (ESBs) to be equal to or less than that of diesel school buses.
Electrifying school buses is a top priority for the Biden administration. The $1.2 trillion infrastructure plan supported by the administration includes $7.5 billion to replace thousands of diesel-powered school and transit buses with zero-emission electric vehicles. However, with approximately 480,000 school buses across the nation, the $7.5 billion split across both sectors represents only a fraction of the funding needed to electrify all school buses across the country. Nuvve’s V2G technology and the company’s recently announced plans to form a joint venture (“Levo”) to provide fully financed options for customers will help bridge the gap between the need to electrify the nation’s transportation fleet and the funding available to do so.

Sensata GigaFuse Chosen by Charging OEMS
Sensata Technologies (NYSE:ST), a leading industrial technology company and provider of sensor-rich solutions that create insight for customers, announced its new power disconnect solution has been chosen by several leading charging infrastructure OEMs to enable faster and safer DC fast charging. Sensata’s unique solution combines contactors and GigaFuses from its leading Gigavac product brand to provide customers with a value-added contactor module, simplifying their installations while delivering safer and more effective system protection compared to traditional contactor and thermal fuse pairings.
To compete with traditional internal combustion engines, EVs need faster charging times, so EV Charging Systems are quickly migrating from 400V to 1,000V and from 50kW to up to 350kW to shorten charging times to less than 20 minutes. While higher voltage and current levels reduce charging times, they increase the safety risks and design challenges for the systems. High voltage contactors provide safe circuit continuity while fuses are required in tandem for circuit-protection in the event of a hazardous short circuit event.
The increases in voltage and current levels not only require contactors with higher breaking capabilities, but also make the contactor and fuse pairings more technically challenging. To address these challenges, DC fast charging infrastructure OEMs are seeking safer, higher performing and more comprehensive solutions that improve on the traditional contactor and thermal fuse pairing.
Sensata’s GigaFuse offers several advantages compared to a conventional DC thermal fuse, including the ability to:
- Open a circuit within 3 mS; faster than a conventional DC thermal fuse
- Open a circuit closer to normal operating conditions without nuisance tripping, resulting in less potential risk of damage
- Pair more easily with the contactor because of its unique electro-mechanical triggering mechanism
- Help prevent overloading, improving the performance of the contactor in the circuit
- Reduce thermal resistance; typically, 0.15 mohm
- Eliminate thermal aging due to low heat generation
Sensata’s packaged power disconnect module includes high voltage contactors and GigaFuses that are harnessed to a mounting plate. The solution delivers overcurrent and short circuit protection and provides the following benefits for the whole charging system:
- Increases safety/reduces risk of damage
- Increases thermal performance/system efficiency
- Provides fast and reliable circuit protection
Nick Moelders, Vice President, Electrification at Sensata Technologies explains, “Our recent wins with major Charging Infrastructure OEMs demonstrate the additional value we provide to our customers as we move from being a component supplier to a leading electrification solutions provider. Working engineer-to-engineer with the most innovative companies allows us to learn and adapt to the needs of the rapidly transforming clean energy market.”
