The organisation is presently focused on the release of a high voltage version of its popular Smart Flow\u00ae FiC-15 e-fan, where it was first to market, followed by the FiC-31 HV e-fan. \u201cBoth e-fans were created for use in medium- and heavy-duty on-highway vehicles and are a great option for electric industrial vehicles,\u201d explains Kevin Puszczewicz, EMP\u2019s VP sales and customer service. \u201cThe robustly-built brushless fans are currently being integrated into several fuel cell electric vehicle (FCEV) and battery electric vehicle (BEV) cooling applications.
\u201cA real differentiator for EMP is that our e-fans maintain an air-cooled design, as opposed to others in the sector which need to be liquid-cooled. This essentially eliminates the requirement for additional cooling capacity needed for liquid-cooled systems.\u201d
The FiC-15 is designed to run at a voltage range of 500 to 850V with up to 3kw of power, and the FiC-31 up to 25kw of power, depending on application specifications. The FiC-31 HV motor controller is also built to be modular.
\u201cIn addition, EMP has introduced the WP150 HV high-performance, long-life electric water pump, for use in cooling systems within extreme environments. These e-pumps can be used in off-road applications, power generation, and large vehicle applications, including fuel cell, diesel, electric, and other alternative fuel applications,\u201d Puszczewicz adds.

The WP150 HV e-pumps are designed to run at a voltage range of 500 \u00a0to 850V with up to 3kw of power, depending on application specifications.
Utilising Smart Flow\u00ae technology, the new HV fans and components are Controller Area Network (CAN) controlled to provide variable speed for precise control as well as full diagnostic capabilities.
Advantages of using HV components<\/strong>
\u201cWhen compared to low voltage components, EMP\u2019s HV options provide a number of advantages to commercial electric vehicles,\u201d Puszczewicz continues. \u201cFirstly, they eliminate the need for costly high amperage DC\/DC convertors, a notable benefit.
\u201cDue to its power and heat output, a converter dedicated to providing power to all 12 or 24V components typically requires its own cooling. Removing that converter not only eliminates its own weight and added wiring complexity, but it also removes the additional cooling system. This has been the major driver for OEMs to switch e-fans from low voltage to high voltage.
\u201cAnd by simplifying the vehicle architecture, we\u2019re additionally improving space availability within commercial EVs, which is a limited resource. It\u2019s a real challenge for OEMs to create the maximum amount of space for battery packs to increase power and range, while still remaining under weight limits and packaging dimensions. More efficient thermal management systems remove redundant componentry to allow for increased battery architecture, something that could be critical to an OEM\u2019s competitive edge.
\u201cThere is also increased performance because we are able to physically spin the fan blade faster due to the higher voltage.\u201d
According to Puszczewicz, EMP can provide full systems with these high voltage fans, offering the end customer a complete plug-and-play solution for vehicle cooling needs. \u201cEMP will continue to optimise technology for the commercial and heavy-duty electric vehicle sector, with a focus on adding to our HV pipeline based on growing market needs, such as HV air compressors, additional fan sizes and more.\u201d<\/p>\n\n\n\n![\"\"](\"https:\/\/www.concentricab.com\/content\/uploads\/2023\/11\/Hybrid-fan-system.png\")
