Nidec’s Motor for Battery-assisted Bicycles is Adopted for Use in Taiyo Yuden’s Regenerative System that Keeps Them Running for 1,000km per Charge

　　Nidec Corporation (TSE: 6594; OTC US: NJDCY) (“Nidec” or the “Company”) today announced that a motor that it developed for regenerative system-based battery-assisted bicycles has been adopted for use in FEREMO™, the regenerative power assistance system*1 that Taiyo Yuden Co., Ltd. (“Taiyo Yuden”) produced keeps a bicycle running for up to 1,000km on a single charge*2　　FEREMO™, the regenerative power-assisted system that Taiyo Yuden developed, uses its power-assisting motor as a generator when the person on a bicycle puts on the brake or has his/her feet off the pedals, to collect and reuse motion energy.　　This feature enables FEREMO™ to enjoy a significantly longer per-charge running distance, or up to 1,000km, than conventional power-assisting systems. In addition, with speed suppressed while the regenerative system is on, one can ride a bicycle safely even on a downhill.　　Nidec’s power-assisted bicycle motor installed in FEREMO™ was designed exclusively for the system. While conventional power-assisting systems merely engage in powered operation (i.e., driving a motor with battery-generated electricity), this new motor operates as a generator when a bicycle decelerates, engaging in regeneration (i.e., rotating a motor with external power to generate electricity). In comparison with the Company’s other existing motors, this latest model boasts 30% more regenerative electric power, which is an industry-leading power generation efficiency, to help FEREMO™ achieve the 1,000km travelling distance. Furthermore, unlike assistance-only motors, load is constantly on the motor, making it more durable, low-noise, and radiation-efficient than conventional models.　　As the world’s leading comprehensive motor manufacturer, Nidec stays committed to developing products with its technologies to make light, thin, short, and small products, as well as productivity enhancement and control technologies; and to proposing, at an overwhelming speed, revolutionary solutions that contribute to the lives of people around the world.　　*1: FEREMO™ are Taiyo Yuden Co., Ltd.’s registered trademark or trademark for use in Japan　　*2.

ROHM：New Compact VCSEL Proximity Sensor Contributes to Greater Miniaturization and Battery Capacity in Wireless Earbuds and other Wearable Devices

　　ROHM has developed a compact 2.0mm × 1.0mm proximity sensor, the RPR-0720, optimized for applications requiring attachment/detachment and proximity detection.　　As the use of IoT continues to grow, sensor devices that play a critical role are requiring greater miniaturization and functionality. ROHM offers a lineup of proximity sensors that combine light emitting and receiving elements in a single package, providing unmatched versatility that has led to widespread adoption in a range of applications, from mobile devices to industrial equipment. Particularly for wearable devices, in response to the growing demand for small proximity sensors that can support improved designs and an increase in the number of parts resulting from higher functionality, ROHM developed a compact proximity sensor that integrates a VCSEL and sensor IC.　　The RPR-0720 is an optical sensor module that adopts a VCSEL featuring higher directivity than LEDs as the light emitting element and a sensor IC for the light receiving element. Compact size is achieved by optimizing the module structure using in-house chips, reducing area by approximately 78% compared to conventional products. At the same time, the wide input voltage range (2.7V to 4.5V) of the built-in VCSEL eliminates the need for a peripheral voltage booster circuit (i.e. consisting of a power supply IC, three capacitors, and one inductor) when using a Li-ion battery, contributing to greater space savings that leads to smaller applications and increased battery capacity. This makes it suitable not only for sensing attachment/detachment, but also for detecting various conditions in a wide range of applications.　　Going forward, ROHM will continue to develop sensing products that meet customer needs by combining original light receiving and emitting elements to further improve energy savings and convenience.　　Product Lineup　　Application ExamplesSuitable for a wide range of applications that use light reflection to detect conditions.　　◆ Attachment/detachment detection of wireless ear buds, smart watches, gaming console controllers, VR headsets, and the like　　◆ Paper detection in printers, copiers, shredders, and other office automation devices　　◆ E-cigarette cartridge/liquid detection　　◆ Detecting various conditions in smartphones and laptops　　TerminologyVCSEL　　Short for Vertical Cavity Surface Emitting Laser, a type of laser diode that can emit light directly from the surface. Although conventionally used for communication, it is increasingly being adopted in recent years as a light source for the optical block in sensing systems.

AMEYA360:Next-Gen EVs Need Battery and Powertrain Innovations

　　At the recent Advanced Automotive Technology Forum 2023, from EE Times, industry experts discussed some of the battery and powertrain innovations needed for the next generation of electric vehicles (EVs), and challenges the industry faces to implement them.　　An all-electric vehicle. (Source: U.S. Department of Energy)　　EVs have been around for well over a decade. But while their adoption is growing, it will take some time before they capture a sizeable share of the market. For example, out of approximately 80.6 million new cars sold globally last year, less than 10% (7.8 million) were electric, according to a slide presented by Patrick Le Fèvre, chief marketing and communications officer at Powerbox.　　Meanwhile, sales of cars are increasing and the number of vehicles on the road is growing, too. If today there are around 1.6 billion vehicles worldwide, by 2035 that number will grow to nearly two billion, according to the slide from Powerbox. In the EU, 2035 will be the year when sales of new cars with internal combustion engines (ICEs) will be banned. So, by that time, most automakers will have introduced top-to-bottom EV lineups.　　There are many reasons why the adoption rate of EVs is relatively slow, and perhaps the best way to speed it up is to make EVs more attractive in general. There are several ways to do so, but many innovations are required.　　For example, batteries and power electronics are among the major challenges. Specifically, as EVs require up to 20× more power compared with traditional automobiles, they present a considerable challenge for power experts in terms of building energy-efficient power conversion solutions, powertrain development and battery technology.　　Converters and inverters need work　　Today, most hybrid/plug-in hybrid electric vehicles (HEV/PHEV), as well as EVs, use converters and DC-AC invertors that comprise of silicon-based insulated gate bipolar transistors (IGBTs). These components are, in many cases, not compact and are not very efficient, yet they are cheap as they have been around for decades, according to a slide demonstrated by Pietro Scalia, director of automotive traction solutions at Onsemi.　　For now, IGBTs may be good enough for most mass market applications. But the HEV/PHEV market will decrease as car manufacturers focus on battery-powered EVs (or BEVs), so higher-performance converters and inverters will get more widespread as EVs tend to feature higher performance traction motors.　　Furthermore, while sedans and crossover EVs will remain the most popular types of vehicles with the highest market shares, SUVs, trucks and sports cars will see increased demand after 2025, which will rise demand for >250kW electric drives, according to Onsemi’s slide. This will increase demand for higher performance, higher efficiency, and smaller converters and invertors.　　EV, HEV, and PHEV market trends and power class segmentation. (Source: Onsemi)　　Building compact and efficient power-conversion solutions requires using wide-bandgap (WBG) semiconductor materials, such as gallium nitride (GaN) and silicon carbide (SiC). When compared with silicon, they offer higher power density (high electron mobility and breakdown voltage allows to build smaller and lighter PSUs), high efficiency (less power loss and lower temperatures, which lead to reduced cooling requirements and lower costs), fast switching speeds (leads to improved power conversion efficiency and reduced electromagnetic interference), and wide temperature ranges (higher reliability and durability).　　While both GaN and SiC offer tangible advantages in power conversion applications, they are not interchangeable in all use cases, and the choice between the two depends on the specific requirements. For example, GaN has a higher electron mobility and can achieve higher power densities, which makes it more suitable for in-vehicle applications and chargers.　　Actually, usage of GaN for in-car electronics like LiDAR, infotainment and headlights has been increasing and will keep increasing in the future. Furthermore, some traction motors now also use GaN converters, said Alex Lidow, CEO and co-founder of EPC, a supplier of GaN-based devices.　　“Today, if you have a LiDAR system on a car, whether it be autonomous or just a level two or level three, that has GaN devices in it,” he said. “We have been on headlights with GaN for almost 10 years, infotainment systems, wireless charging, other than for the car, but wireless charging inside the car, and all sorts of advanced things like augmented reality heads up displays. These are all homes for GaN. As sure as the sun comes up in the morning, [GaN] will replace silicon, and everything that is in the 48-V range. We will see whether or not it moves to the traction [motors], and the onboard charging in the future, as well.”　　Uses of GaN in cards. (Source: EPC)　　On the other hand, SiC can handle higher voltages and offer better thermal performance, making it a suitable choice for high-power and high-temperature applications, such as traction inverters in EVs. Also, SiC technology is more mature and is sometimes cheaper to implement. Some SiC-based inverters may be cheaper than IGBT-based inverters.　　“Finding the sweet spot of the performance versus the cost of the material [is important], I had a sweet spot at 250kW, where I can easily demonstrate that SiC is cheaper than IGBT in terms of area given the delta cost, calculating the extra need the you have to put in place for dissipating, you can have a much cheaper solution with silicon carbide,” Onsemi’s Scalia said.　　It goes without saying that with higher efficiency comes miniaturization and weight loss on components levels, which in turn allows us to build more comfortable cars with longer range or make cheaper cars with sufficient range for everyday needs. Cost-efficient SiC MOSFETs along with innovative packaging opens doors to lower-cost EVs with decent motors.　　“One part of our strategy at Qorvo [is addressing the] explosion of lower powered cars that are going to come,” said Anup Bhalla, chief engineer of power devices at Qorvo.　　There is a persistent need in “getting the cost out of the solution for the people who want to build EV traction inverters and to make the [EV] technology more accessible,” he added.　　Finding the right balance between an inverter or converter cost, efficiency, and reliability is a challenge that makers of SiC and GaN components, as well as EVs, must address whenever they build a new car, converter or inverter.　　“When we tackle an inverter design with a customer, there is a lot of back and forth how they can extract the maximum benefit [as there are] regular tensions between efficiency they want to get the cost they are willing to pay,” Bhalla said. “This cost is always tied in with the reliability impact of trying to go too cheap. This system has to in the end be very reliable. And everybody has their own take on how they need to build the inverter to define their own advantage.”　　Bhalla demonstrated a compact dual side cooled 150kW (12ohm/1200V) inventor comprising of three SiC MOSFETs in a top cool discrete package, as well as another invertor solution featuring top-cooled SiC MOSFETs that could be used for such applications.　　“People will need to put traction inverters designed differently, maybe designed right around the motor, needing different form-factors,” he said. “Then they need different kinds of packaging solutions. The great thing is that these devices have become so efficient, that we can consider putting them into a top-cooled package getting a moderate amount of heat out and then build a traction inverter out of it.”　　Onsemi’s slide claimed that usage of its EliteSiC Powertrain extends range by 8 to 12% due to higher efficiency compared with IGBT-based solutions. Furthermore, for high performance inverters, SiC is preferrable for many reasons, so its adoption is set to grow.

Ameya360:Li-ion Battery Material Prices Drop in January Amid Slowing Growth in Chinese NEV Market

　　There was an across-the-board decline in prices of upstream (raw) materials for lithium ion (Li-ion) batteries in January as participants in the industry chain in China were focusing on inventory consumption, according to TrendForce. The decline was especially significant for upstream materials related to cathodes, cathode materials, and battery electrolytes.　　The average price of lithium carbonate, which is the most costly among the upstream materials related to cathodes, fell by 12% month-on-month (MoM). Lithium hydroxide also suffered a price drop, but the demand for this material was bolstered by orders from regions outside China. Compared with lithium carbonate, lithium hydroxide experienced a more moderate price slide. Nevertheless, the average prices of battery-grade lithium carbonate and lithium hydroxide both dipped below Rmb500,000 per metric tons. Turning to electrolytes and related upstream materials, the average price of LiPF6 (lithium hexafluorophosphate) fell by 11% MoM for January. This, in turn, caused the average price of electrolytes to drop by 11~15% MoM for the same month.　　TrendForce points out that China initiated the phase-out of its NEV (new energy vehicle) subsidy at the start of 2023. Other regions of the country have introduced other subsidy policies in the hope of stimulating consumption, and the preferential rate for the purchase tax on NEV purchase has been extended to the end of 2023.　　However, a significant portion of Chinese consumers’ demand for new vehicles was expended in 4Q 2022 when the country saw energetic promotional activities that aimed to spur NEV sales. Moving into this first quarter, the Chinese car market has been affected by the low season. On the whole, NEV sales in China has slowed down recently and thereby caused a general decline in prices of upstream materials for Li-ion batteries. On the other hand, the drop in material prices has reduced some of the cost pressure on the manufacturing of Li-ion batteries.　　Regarding price trends of NEV power battery products in China, prices of battery cells on the whole fell by about 1% MoM for January. Various cell types including ternary cells and prismatic LFP (lithium iron phosphate) cells experienced a MoM decline of 1~2%. TrendForce projects that their prices will go down further in February.　　In the market for energy storage battery cells, most products are LFP cells, and their prices fell by 2% MoM for January to reach the average of Rmb0.94 per watt-hour. Also, due to the policy support that the Chinese government has been providing for the development of energy storage technologies, the demand for Li-ion energy storage batteries is expected to rebound slightly going forward. Prices of energy storage battery cells are currently projected to remain mostly flat or drop a bit for 1Q23.　　Lastly, looking at Li-ion battery cells for consumer electronics, the average price of LCO (lithium cobalt oxide) cells in China came to around Rmb9.9 per amp-hour in January. Transactions were low in the market for consumer batteries due to the slumping demand for electronic devices. Furthermore, prices of the upstream materials for LCO cathodes kept sliding.　　Looking ahead, the market for LCO materials is expected to remain weak in the short term, it will witness a further price decline in February.
