Hexagon Agility與Brudeli綠色出行公司（Brudeli Green Mobility）達(dá)成了一項(xiàng)合作，共同為北美市場(chǎng)打造7-8級(jí)壓縮天然氣/可再生天然氣（CNG/RNG）混合動(dòng)力重卡。
在拉斯維加斯舉辦的2024年美國(guó)綠色交通及充電樁展（ACT Expo 2024）上，Hexagon Agility宣布與挪威電動(dòng)車傳動(dòng)技術(shù)供應(yīng)商Brudeli達(dá)成了一項(xiàng)合作，旨在集成Hexagon Agility的CNG/RNG系統(tǒng)與Brudeli的插電式混動(dòng)系統(tǒng)。據(jù)稱，Brudeli的這項(xiàng)技術(shù)將能夠使車隊(duì)在保留柴油內(nèi)燃機(jī)工作周期的同時(shí)降低燃油成本，助力OEM實(shí)現(xiàn)全球脫碳目標(biāo)。
Hexagon Agility的銷售與系統(tǒng)開發(fā)執(zhí)行副總裁Eric Bippus介紹稱：“Brudeli的PowerHybrid技術(shù)使車隊(duì)運(yùn)營(yíng)商能夠在保留天然氣發(fā)動(dòng)機(jī)的動(dòng)力、性能和燃油成本效益的同時(shí)，充分利用電能的效率。我們認(rèn)為，混動(dòng)技術(shù)在未來(lái)商用卡車領(lǐng)域?qū)l(fā)揮舉足輕重的作用，因此我們很高興能積極主動(dòng)地將這項(xiàng)技術(shù)推向市場(chǎng)，搶占先發(fā)優(yōu)勢(shì)。”
該系統(tǒng)基于雙電機(jī)系統(tǒng)，使動(dòng)力總成能夠在串聯(lián)和并聯(lián)混動(dòng)模式之間切換。據(jù)稱，該系統(tǒng)將使卡車能夠根據(jù)車速、負(fù)載、驅(qū)動(dòng)模式和電池電量等因素，始終保持峰值效率運(yùn)行。
據(jù)Brudeli稱，換擋會(huì)使車輛減少高達(dá)25%的加速功率，但PowerHybrid系統(tǒng)能夠在換擋過(guò)程中將動(dòng)力傳遞到驅(qū)動(dòng)輪。當(dāng)卡車下坡或減速時(shí)，該系統(tǒng)還可以啟用再生制動(dòng)功能。此外，該系統(tǒng)還可以在電機(jī)曲線進(jìn)入低效區(qū)間時(shí)開啟輔助用的內(nèi)燃機(jī)，并在車輛處于靜止、停滯狀態(tài)，或需要輸出功率時(shí)關(guān)閉發(fā)動(dòng)機(jī)，從而提高系統(tǒng)效率。
Brudeli表示，該系統(tǒng)允許車隊(duì)選擇現(xiàn)有的清潔能源方案，實(shí)現(xiàn)靈活運(yùn)營(yíng)。Brudeli的首席執(zhí)行官Lasse Bjørkhaug說(shuō)：“人們不斷認(rèn)識(shí)到，必須對(duì)占美國(guó)交通運(yùn)輸領(lǐng)域總碳排20%的中卡和重卡進(jìn)行排放控制。因此我們希望與Hexagon開展合作，幫助這些難以實(shí)現(xiàn)電動(dòng)化的細(xì)分市場(chǎng)中的車隊(duì)實(shí)現(xiàn)敏感區(qū)域內(nèi)的零排放運(yùn)營(yíng)，同時(shí)利用可再生天然氣（RNG）消除長(zhǎng)途運(yùn)輸?shù)睦锍探箲]。此外，具備電動(dòng)車的卓越性能并減少負(fù)載限制，也能為車隊(duì)運(yùn)營(yíng)商帶來(lái)顯著效益。”
PowerHybrid插電式混動(dòng)的電池系統(tǒng)可使用2級(jí)充電方式，并提供75英里（120 km）的純電續(xù)航里程。Brudeli稱其旨在成為美國(guó)市場(chǎng)上首個(gè)實(shí)現(xiàn)商業(yè)化的近零排放汽車（NZEV）技術(shù)。一旦獲得NZEV認(rèn)證，搭載PowerHybrid系統(tǒng)的7-8級(jí)卡車將符合已在加州和其它10個(gè)州通過(guò)的ACT（Advanced Clean Truck）法規(guī)的要求。
去年12月，Brudeli宣布與EMOSS合作，在一輛原型卡車上集成Brudeli的PowerHybrid模塊。Brudeli和Hexagon Agility計(jì)劃于2026年推出首批采用該技術(shù)的試點(diǎn)卡車，并于2028年開始批量生產(chǎn)。
Hexagon Agility announced a collaboration with Norwegian EV transmission supplier Brudeli Green Mobility at the 2024 ACT Expo in Las Vegas. The partnership’s goal is the integration of Hexagon Agility’s CNG/RNG systems with Brudeli's plug-in PowerHybrid system. This technology will reportedly offer fleets the capability to maintain diesel ICE duty cycles while providing fuel cost savings and help OEMs achieve global decarbonization goals.
“The Brudeli PowerHybrid enables fleet owners to retain the power, performance, and fuel cost-savings offered by natural gas engines, while simultaneously harnessing the efficiencies of electric,” said Eric Bippus, EVP sales & systems development, Hexagon Agility. “We believe hybrids could play a role in commercial trucking in the future, and we are excited to take an active role bringing that to the market.”
Brudeli’s PowerHybrid unit electrifies existing CNG/RNG trucks by allowing them to utilize up to 80-percent pure electric energy. The system is based around a dual electric motor system that enables the powertrain to alternate between serial and parallel hybrid modes. The system will reportedly allow trucks to operate at peak efficiency depending on factors such as vehicle speed, load, driving patterns and battery SOC.
According to Brudeli, its PowerHybrid unit enables transfer of power to the drive wheels during a gear shift. Brudeli claims that as much as 25% of acceleration power is lost during gear shifts. The unit can also perform regen duty when the truck is traveling down a grade or when reducing speed. The system also realizes efficiency gains by assisting the combustion engine at low efficiency areas of the motor curve and also turns the engine off engine when the vehicle is stationary or when standstill or when power take off is needed.
Brudeli states that this system provides flexibility for fleets to operate with clean energy options that are readily available. “There is growing awareness of the need to cut emissions from medium- and heavy-duty trucks, which make up more than 20% of overall CO2 emissions in the U.S. transport sector,” said Brudeli CEO Lasse Bjørkhaug. “Our partnership with Hexagon enables fleets in hard-to-electrify market segments to achieve zero-emission operation in sensitive areas, while eliminating range anxiety for longer trips with RNG. Additionally, fleet operators will benefit from trucks that offer superior electric-like performance without the same payload restrictions.”
The PowerHybrid plug-in battery system is capable of Level 2 charging. The system offers 75 miles (120 km) of electric-only range. Brudeli claims that this is intended to be the first NZEV-compliant (Near Zero Emission Vehicle) technology commercially available in the U.S. market. Once NZEV certified, the Class 7 and 8 trucks with outfitted with Brudeli’s system would comply with the Advanced Clean Truck (ACT) rule, which has been adopted by California and ten other states.
Brudeli announced in December of last year that it had partnered with EMOSS to outfit a prototype truck with the Brudeli PowerHybrid module. Brudeli and Hexagon Agility plan to introduce the first pilot trucks with this technology in 2026, with serial production slated for 2028.
