4 Technology Trends Defining the Future of New Energy Electric Vehicles
New energy electric vehicles are now considered the future of most transportation sectors – an incredible change since even five years ago, new energy electric vehicles were considered a niche product, and in the 20s It won't matter in a year or so. It's surprising how quickly this perception has disappeared.
Now let us analyze the development trend of new energy-electric vehicle technology.
Advanced Li-Ion Cells and Battery Packs
Advanced lithium-ion refers to silicon and lithium metal anodes, solid electrolytes, high nickel cathodes, and various battery design factors. Given the importance of the new energy electric vehicle market, especially battery new energy electric vehicles in determining battery demand,
Lithium-ion batteries are expected to maintain their dominance. However, incremental improvements to the cathode, anode, cell design, and energy density are key.
Innovation also happens at the packaging level. Assembling a battery pack requires a variety of materials, including thermal interface materials, adhesives, gaskets, dipping, potting, fillers, and more. A general trend towards larger cell form factors and non-modular cell-to-pack designs is underway, reducing the number of connections, bus bars, and cables between cells and modules.
In automotive power electronics (inverters, onboard chargers, DC-DC converters), significant progress is being made to improve powertrain efficiency, allowing for lower battery pack capacity or increased range. One of the key ways to achieve higher efficiency is to transition to 800V or above SiC MOSFETs and high-voltage automotive platforms.
In fact, Renault, BYD, GM, Hyundai, and others have announced 800V vehicle platforms that will use SiC MOSFETs in their power electronics by 2025.
Experts say this transition presents new challenges for power module packaging materials, as higher switching frequencies, higher power densities, and higher operating temperatures are required while maintaining a 15-year lifespan. The report found that by 2030, 800V platforms and SiC inverters will rise to at least 10% market share. As the power density of semiconductor chips increases exponentially, new double-sided cooling designs, copper wire bonds, and lead frames will enable this trend.
The electric motor market is still evolving, with new designs increasing power and torque densities and more consideration for the materials used. Experts believe that developments such as axial-flux motors and various OEMs could eliminate rare-earth materials entirely.
Electric motors have several key performance indicators. Power and torque density can improve driving dynamics in a smaller, lighter package, where weight and space are at a premium in NEVs. Another key area is driving cycle efficiency.
Increased efficiency means less of the precious energy stored in the battery is wasted when the vehicle accelerates, resulting in increased range for the same battery capacity. Due to the many different considerations in motor design, the NEV market has adopted several other solutions, including permanent magnet motors, induction motors, and wound rotor motors.
Experts believe that while motors will still be dominated by permanent magnets, there will be opportunities for non-magnetic variants as cost and sustainability become paramount issues in the coming years.
The Fuel Cell
Although the market is still growing, supported by government support, the opportunity for fuel cells in the automotive market is limited. Deploying fuel cells in vehicles is not a new concept. Major OEMs including Toyota, Ford, Honda, GM, Hyundai, Volkswagen, Daimler, and BMW have invested heavily in advancing the technology over the past 30 years.
For passenger cars, a lot of effort and expense have been invested in developing fuel cells. Still, only two major OEMs, Toyota and Hyundai, have produced FCEV vehicles by 2022, while fewer than 20,000 FCEVs will be sold in 2021.
The deployment of fuel cell vehicles faces considerable challenges, including reducing the cost of fuel cell system components and rolling out sufficient hydrogen refueling infrastructure. Equally important is the availability of low-cost "green" hydrogen, which is produced by electrolyzing water using renewable electricity, and the analysis highlighted in the new report is crucial for FCEVs to provide the environmental credentials to sell them.
