Many nations are passing legislation to boost the number of electric cars (EVs), with the objective of ultimately phasing out or outright prohibiting petrol and diesel automobiles.
While environmental considerations may have driven early adopters, a large section of the market is also worried about EV range restrictions and charging delays.
The automotive sector is under pressure to innovate and provide solutions that appeal to a wider audience, which is fueling the trend towards greater battery voltages.
The majority of passenger EVs on the road today are powered by 400-V batteries. EV buses and trucks are 600-V vehicles, while 800 V is being used for passenger cars.
A brushless dc (BLDC) motor’s primary components are the rotor, which creates a dc magnetic field (usually permanent magnets or a dc armature winding), and the stator, which comprises copper windings through which alternating current (AC) is transmitted.
The interplay of the rotor magnetic field and a spinning magnetic field created by time-controlled currents in the stator windings is what drives motion.
As the motor operating voltage increases for a given input power, the input RMS current and, consequently, the stator winding copper losses decrease. When using an 800-V supply instead of a 400-V source, losses are often decreased by a factor of four.
This allows for a reduction in the diameter of the copper winding wire, which reduces total volume and boosts packing efficiency, allowing for smaller motors. Lower current needs in an 800-V system decrease not just motor copper losses, but also losses in the overall system wire loom, saving weight, space, and money.
In most cases, 800-V systems go from silicon-based IGBTs to silicon-carbide (SiC) MOSFETs. SiC devices have substantially faster switching rates and, as a result, smaller switching losses. As a result, the operating frequency rises, lowering motor losses owing to lower harmonic currents.
Reduced weight enhances handling and acceleration, which is important in the high-end sports vehicle market. Together with decreased losses, it improves range, which is directly related to battery and power consumption.
Reduced weight, volume, and losses provide vehicle designers with alternatives for balancing cost, performance, and range for certain market segments. The lower cost makes the solution more accessible to the mid-range consumer market, rather than merely high-performance automobiles.
When making the conversion to electric vehicles, one of the most important factors to consider is range. For some, it’s a question of convenience and the desire to make long travels simpler. Extending the range of commercial vehicles implies more efficient delivery routes, more time spent on the road, fewer vehicles to cover the same region, and lower operating costs.
Plug-in hybrid electric vehicles (PHEVs) and hybrid electric vehicles (HEVs) have maintenance and safety requirements similar to conventional cars, whereas all-electric vehicles require less maintenance. Manufacturers are producing and releasing maintenance and safety manuals for these cars.\
Because PHEVs and HEVs employ internal combustion engines, their maintenance requirements are comparable to those of standard automobiles. Because of regenerative braking, the electrical system (battery, motor, and related electronics) normally requires minimum planned maintenance, and brake systems typically last longer than those on conventional cars.
The Global EV High Voltage Colorants Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Lanxess has created a new colorant that may be used to permanently color polyamides (PA) and other polymers with the RAL 2003 tone of orange. Macrolex Orange HT is a very heat-stable, light-fast, and weather-resistant organic dye with exceptional color strength and brilliance.
According to Lanxess, unlike most traditional dyes, Macrolex Orange HT is appropriate for not just PA but also other common plastic types such as polycarbonate (PC) or polyphenylene sulfide (PPS), which generally offer a difficulty for colorants due to their high processing temperatures.
The new halogen-free colorant provides constant high-quality and precise coloring (dE 0.7), which is especially crucial for orange tones. A dE1 hue variation is normally undetectable by humans.
Furthermore, the new LANXESS high-voltage orange is cost-effective due to its high color strength.
These new items have already been thoroughly tested under realistic situations. They coloured compounds with Macrolex Orange HT at the plastics technical center in Dormagen in collaboration with Lanxess’s High Performance Materials business unit and evaluated them for compatibility in plastics processing.
Macrolex Orange HT may be used to color various high-quality plastic items, such as housings for tools and other electronic equipment, as well as technical plastics for automotive components and structural applications, in addition to high-voltage applications.
Electric vehicles are inherently subjected to greater voltages and currents than combustion engines. Voltages in the battery circuit AC voltages surpassing V and DC voltages over V are already deemed potentially life-threatening in the engine circuit.
This is why the live components of an electric motor are bright orange in order to be clearly detected. As a consequence, the new Macrolex Orange HT product contributes to lowering the risk of accidents when handling electric motors.
Lanxess Macrolex dyes have a wide variety of possible uses and are highly compatible with a wide range of polymer types and production methods. They also comply with a slew of legislative standards for usage in food packaging and children’s toys.The Polymer Additives business unit’s colorant portfolio includes around 150 items.
