Electrification Efforts Advance Through Engineering Collaboration

Partnerships between companies are becoming increasingly important to help advance new technology.

Industry partnerships are nothing new in the heavy-duty  equipment design industry. However, their prevalence has seemed to grow in  recent years particularly as development efforts for electrification have   progressed.

In late 2020, Daimler and Volvo Group announced they would  work together on a joint venture aimed at advancing development of fuel cells  for heavy-duty on-highway vehicles. Both companies have been actively working  in the electrification space and will be able to bring together years of experience.

When it comes to electrification of mobile applications,  there are a variety of technologies coming together and no single company can  master and integrate those technologies in order to provide customers an  optimized solution, says Kimmo Rauma, Vice President of Danfoss Power  Solutions.

Because of this, company collaborations are becoming  increasingly important to help advance new technology. Companies which  collaborate with one another can bring their individual expertise to a project.  Rauma says each company’s engineering team can focus on designing the  components it already knows best; then the teams can work closely together to bring  their technologies into a single, cohesive system that will meet customer   requirements.

Creating optimized solutions

Danfoss Editron—a business division of Danfoss Power  Solutions—announced in April 2021 it was partnering with Meritor Inc. and  Electra Commercial Vehicles to form the Meritor-led Electric Powertrain  Integration for Heavy Commercial Vehicles (EPIC) consortium. The consortium’s  goal is to develop advanced electric powertrains.

Each company will bring its own industry expertise to the project.  Danfoss Editron, for instance, will bring its knowledge developing electric   motors and inverters. According to Rauma, the company will be looking at how it  can increase power density further through adjustments to the mechanics,  cooling and total system package.

He says Danfoss Editron will work together with Meritor and  Electra to create an e-axle package which uses less materials to provide a more  optimized solution in terms of cost and performance.

Ensuring a high level of efficiency and performance is a key  aspect of the project, as well. To achieve this, Rauma says new technologies  for the motor and power electronics used for the controller will be necessary.  “We want to introduce a silicon carbide design so that we have the most   sophisticated control methods in this application area.”

When developing these types of systems, Rauma says companies  can optimize the components individually or look at the whole picture and optimize  all the components as a single unit to get the best solution package. “Our  target with Meritor is to be close partners so we can optimize the package in a  way that the competition cannot match us,” he says.

“The cooperation really brings all the key understandings of  these companies together so that we can make an optimal solution for the end  customer,” he adds.

Rauma says the partnership with Meritor is a very close one “because  otherwise we are not able to meet the timetables and the technology targets  that we have put ourselves against.” The companies don’t want to create  technology that is already available in the market, but instead bring something  new to the industry.

“The engineering teams are working more or less as one, sharing information and trying to find out the methods that [enable] the next  steps of what is available or possible,” says Rauma.

Partnership can expand application uses

In January 2021, Proterra announced it was collaborating  with Komatsu on the development of a battery-electric hydraulic excavator which   Komatsu expects to begin commercial production on in 2023-2024. Proterra will  be providing its battery technology.

This is the first off-highway equipment project for Proterra  which is probably best known for its electric buses. However, its Proterra  Powered business offers battery packs for use in other OEMs’ vehicles and  equipment. Claire McConnell, Vice President of Proterra Powered, says the  company’s battery systems are now utilized in everything from its own transit   buses to school buses and delivery vehicles.

“One of the segments that we've actually been most excited  about and believe is especially right for electrification is construction  equipment,” says McConnell. “It's a major contributor to air pollution, especially  in our cities and neighborhoods where most construction projects are located.”

She says Proterra is very flexible in how it works with  OEM partners and that it is able to bring its full electrification expertise to   partnerships like the one with Komatsu.

Proterra’s battery technology platform is flexible, as well,  which enables it to easily be customized to various applications. McConnell  notes the battery platform offers a high level of energy density and ruggedized  housing to withstand use in harsh operating environments.

“Packaging flexibility helps enable optimal placement of the  Proterra batteries within the Komatsu electric excavator and actually replaces  the need for a normal counterweight used to balance the excavator’s hydraulic   arm movements,” she explains.

Additionally, she says Proterra designs its battery packs  for commercial vehicles from the ground up, which enables it to ensure they  provide the durability and safety required in heavy-duty applications.

公司之间的合作关系对于推动新技术的发展正变得越来越重要。在重型设备设计行业,行业合作并不是什么新鲜事。然而,近年来,特别是随着电气化发展工作的进展,这种情况似乎越来越普遍。2020年底,戴姆勒(Daimler)和沃尔沃集团(Volvo Group)宣布,他们将合作成立一家合资企业,旨在推进重型公路车辆燃料电池的开发。两家公司都在电气化领域积极工作,将能够汇集多年的经验。丹佛斯电力解决方案副总裁Kimmo Rauma说,当谈到移动应用的电气化时,有各种各样的技术结合在一起,没有一家公司能够掌握和集成这些技术,以便为客户提供优化的解决方案。正因为如此,公司合作对于推动新技术的发展变得越来越重要。相互合作的公司可以将他们个人的专业知识运用到项目中。劳马表示,两家公司的工程团队可以专注于设计自己最熟悉的组件;然后,团可以紧密合作,将他们的技术整合到一个单一的、内聚的系统中,以满足客户的需求。


2021年1月,Proterra宣布与小松合作开发电池电动液压挖掘机,小松预计将在2023-2024年开始商业生产。Proterra将提供其电池技术。这是Proterra的第一个非公路设备项目,该公司最出名的可能是其电动巴士。然而,其Proterra Powered业务提供用于其他oem的车辆和设备的电池组。Proterra Powered副总裁克莱尔·麦康奈尔(Claire McConnell)表示,该公司的电池系统目前应用于从自己的公交、校车到运输车辆的各种场合。麦康奈尔表示:“建筑设备是我们最感兴趣的领域之一,我们认为它对电气化尤其有利。”“这是空气污染的一个主要因素,尤其是在我们的城市和社区,大多数建筑项目都位于那里。”她表示,Proterra在与OEM合作伙伴的合作方式上非常灵活,它能够将自己的全部电气化专业知识带入与小松的合作伙伴关系中。Proterra的电池技术平台也是灵活的,这使得它可以很容易地为各种应用定制。McConnell指出,电池平台提供了高水平的能量密度和坚固的外壳,能够在恶劣的操作环境中使用。她解释说:“包装的灵活性有助于优化Proterra电池在小松电动挖掘机中的位置,实际上取代了对正常平衡挖掘机液压臂运动的需求。”此外,她表示,Proterra为商用车辆设计的电池组是从头开始的,这使得它能够确保它们提供重型应用所需的耐用性和安全性。
