XL Fleet and eNow partner to electrify refrigerated trailers

XL Fleet Corp. announced a battery and power electronics development and supply agreement and an investment in eNow, Inc., a provider of solar and battery power systems that enable fully-electric Transport Refrigeration Units (eTRUs) for Class 8 commercial trailers.

Under the terms of the agreement, XL Fleet will supply battery and power electronics systems for the first 1,000 units of eNow’s new electrified refrigerated trailer solutions.


XL Fleet will provide battery and power electronics systems for eNow’s innovative electrified refrigerated trailer solution.

eNow has pioneered the development of mobile solar battery charging systems to the commercial fleet market since 2011. eNow’s patented roof-mounted solar modules store energy in auxiliary batteries used to power lift gates, in-cab HVAC, refrigeration, telematics and other loads such as appliances and lighting. eNow has established itself in a favorable pre-market position to deliver emission-free eTRUs for commercial trailers in the US.

XL Fleet’s partnership with eNow accelerates and expands the company’s existing market opportunity into Class 8 trailers. Approximately 50,000 new diesel-powered refrigerated trailers are sold annually in the US., reflecting a multi-billion dollar potential total addressable market for all-electric solutions.

Each conventional diesel power refrigerated trailer can use as much diesel as a delivery truck uses in a day, so there are large opportunities for diesel and emissions savings with electrified refrigerated trailers. Additionally, the partnership enhances XL Fleet’s strategic position to collaborate with important Class 8 transportation customers, providing potential cross-selling opportunities for XL Fleet’s integrated solutions offering, including electrified powertrains and XL Grid charging infrastructure.

XL Fleet and eNow are collaborating on the design and development of the system that will power eTRUs, as a replacement for conventional diesel-powered systems.

  • XL Fleet is developing the high-capacity integrated lithium-ion battery and power electronics technology that will be installed underfloor on the Class 8 trailer, providing approximately 12 hours or more of run time between charges.

  • eNow will integrate this system into its architecture, including solar panels mounted on the roof of the trailer to maintain the battery charge and extend operation.

Currently available 480V 3 phase shore power will be used for charging of the batteries and powering of the eTRU when idle or during loading and unloading of the trailer. The system will be equipped with a thermal management system to enable year-round operation across North America.

XL Grid will support customers that require new charging or expanded charging infrastructure, or energy solutions. This partnership also builds on XL Fleet’s promise of delivering Electrification-as-a-Service, by giving customers the opportunity to finance or lease the refrigerated trailers and related infrastructure.

eTRUs deliver a lower total cost of ownership and are more environmentally friendly than diesel-powered units currently serving the majority of the market today. eTRUs can be hauled by traditional internal combustion engine or electrified tractors, as a way for fleet managers to immediately and significantly reduce emissions.

XL Fleet and eNow expect to deliver initial eTRUs beginning in the first half of 2022 to customers in industries including food, retail, manufacturing and distribution.

Concurrent with the agreement, XL Fleet invested $3 million in convertible notes in eNow. Additionally, XL Fleet has the right to acquire eNow at a pre-determined valuation.



I count 14 solar panels on the trailer in the picture; if those are full size panels, they can easily generate 5 thousand watts of electricity using the latest technology That's a bunch if they keep em clean.
