3 Things to Know About Charging Your Electric Bus

Electric buses offer a promising opportunity for the future of transit. All-electric buses produce zero emissions, require significantly less maintenance, leverage connectivity and advanced telematics and offer cost savings compared to other powertrain systems.

With the recent launch of the GILLIG Battery Electric Bus, powered by Cummins, there are more opportunities than ever before for cities and organizations to explore the switch to electric vehicles. It is new territory in many applications, including public transit, school systems, and more — but exciting developments and rapidly advancing technology promise new opportunity for transformational innovation.

Managing an electric bus fleet can spark a variety of questions, including concerns about charging the vehicles properly and efficiently. Even though it sounds simple, there are many considerations beyond just plugging in. After all, most drivers have never had to charge a vehicle before! But don’t fret — we’ve broken down the three things you need to know about charging your electric bus.

Three things to know about charging your electric bus.

Vehicle range
Today’s electric buses offer impressive range, but any vehicle’s range can be affected by many factors, including weather, terrain, speed, number of stops, and even bus model.

All drivers should be aware of their vehicle’s average working range. It’s also important to calculate your vehicle’s range capabilities in a variety of situations and environments by collaborating with logistics professionals and engineers, so you’re always prepared for the road ahead. With this knowledge on hand, you’ll be able to plan routes and charging stops more effectively.

Charging infrastructure
As we continue to push forward into the future of electrification, many cities are actively improving the availability of charging stations. For example, Portland, Oregon plans to invest over $10M in a more robust charging infrastructure.

Infrastructure planning is an in-depth process that all transit agencies must take on when preparing to adopt or accommodate an electric fleet. City urban transit planners should also have a deep understanding of the vehicles a city plans to use. Drive cycles, routes and charge time will all help determine the quantity and location of charging stations.

Cities and transit authorities must thoughtfully prepare for the future of electrification beyond investing in just the vehicles themselves. With proper preparation, electrified transit promises to be a transformational opportunity in many cities across the world.

Route plan
Range anxiety is a common concern among electric vehicle adopters. Many new EV drivers worry about how far a vehicle will travel on a single charge, and they may be nervous about trusting even the most accurate, data-supported range estimates.

Careful route planning maximizes your drive time, ensuring you’ll get where you’re going and get power when you need it. Fleet managers work with engineers and researchers to carefully predict range based on the variety of factors mentioned earlier. Using that insight, fleet managers strategically plan routes, including stops and charging, to make sure you’re never left without a charge.

By considering all contributing factors, you’ll maximize the efficiency, safety and reliability of your electric bus and enjoy the many benefits that come with adopting an electric fleet.

Powered by Cummins: XCMG Electric Excavator Makes its Beautiful Debut

Cummins electric excavator

When looking to describe our electrified power applications, many adjectives come to mind, including durable, reliable, safe, and ...beautiful? It's a new (and unusual!) one to add to the list, but this spring, the newly debuted XCMG electric excavator powered by Cummins added “most beautiful” to its list of attributes. Read on to learn more.  electric excavator

Cummins collaborated with XCMG, the 4th largest construction machinery company in the world, to design and build the 3.5 ton electric excavator, which will serve as a technology demonstrator. Often operating on work sites in densely populated towns and cities around the globe, construction equipment must meet stringent emissions requirements and keep noise and disruption to a minimum while getting the job done. The new electric excavator is suitable for working conditions that require more stringent environmental standards and noise reductions.

Powered by Cummins BM5.7E battery modules, the excavator has 45 kWh of battery power. Each battery module is designed for very high shock and vibration capability to endure the harsh conditions of the construction environment. Precise matching between motor and hydraulic system creates an efficient, reliable and quiet drive system, making it ideal for use in urban and suburban construction.

On a single charge of less than six hours, the excavator meets operational needs for a full 8-hour shift. Short charge time means that equipment can be charged overnight, eliminating downtime and taking advantage of off-peak energy savings. 

Construction & Collaboration

Last October Cummins and XCMG cemented their long-standing relationship by signing a strategic cooperation agreement. The agreement ensures close collaboration on developing and integrating comprehensive product lines, value chain and global operations, creating new applications, exploring new markets and sharing resources on research and development for continuous improvement.

Mirror, mirror on the wall…

XCMG excavatorThe XCMG electric excavator powered by Cummins made its debut at this year's ConExpo, North America’s largest construction show held in Las Vegas, Nevada. The excavator earned its descriptor as "beautiful" because it won the award for the most beautiful machine at ConExpo! Beating some tough contenders to the top spot, the excavator was voted the fairest of them all, and we couldn’t agree more. 

After its win in Vegas, the excavator is now back in China where it will be used in a series of performance and customer tests conducted by Cummins and XCMG, to prove capability of the demonstrator and refine a robust solution for the market.

Trusted because it's tested: Cummins-powered GILLIG Battery Electric Bus

Cummins-powered GILLIG Battery Electric Bus

Trusted because it’s tested.  

What do sand bags, mountains, a drone and a film crew all have in common? Well, not much, except that they were all an important part of GILLIG and Cummins’ effort to illustrate the extent of the testing and validation process for the Cummins-powered GILLIG battery electric bus.  

Since 2017 when Cummins and GILLIG announced the partnership to work together on developing an industry-leading all-electric powertrain, both organizations have worked diligently to engineer, test and validate our offering. This is no easy feat, but one that helps distinguish us from the competition. As we bring forward new technologies, we do so with the same commitment to quality customers have come to expect. But how?  

I have not failed. I’ve just found 10,000 ways that won’t work.”  - Thomas Edison

Testing and validation 

A critical piece in bringing forth best-in-class solutions is Cummins commitment to test and validate our offerings against the needs of the customer. For our battery electric system (BES), this means validating products on a component level (e.g. Cummins proprietary BP74E batteries), a powertrain level, and even more broadly working with GILLIG to test performance of the overall bus.  

Ultimately, like most students taking a test, we want to pass. But, just as Thomas Edison noted, the ability to innovate would not be complete without small failures along the way. Testing, and not succeeding is also critical to the process. The failed tests provide insight on the current limits of a product so that designs can be adjusted, and performance optimized to meet the many different scenarios our customers will see in their daily work. We’d be failing our customers, without a few failures along the way.  

Real world conditions

GILLIG and Cummins also take pride in validating our products under real world scenarios, not just ideal conditions. To this end, which was illustrated recently in the gradeability test for the GILLIG bus, various tests were run on the bus as it was loaded with sandbags to simulate the weight of passengers. A powertrain that can operate efficiently, but can only do so empty, is of no value to a community looking to transport people all day, every day.  

Similarly, we work closely with field test customers to refine solutions and deliver a trusted and reliable product. Big Blue Bus in Santa Monica, who received the first field test bus in July 2019, has been a critical partner in providing feedback using real routes and day-to-day operating scenarios. Working with valued customers and end users to identify opportunities that can be enhanced is crucial. The collaboration and partnership that field test customers provide allows us to deliver a product that will meet and exceed customer expectations. Thankfully, the field test has gone well, and as testament to that Big Blue Bus announced that they will be purchasing 18 additional electric buses.  

Trust: a commitment we take seriously 

So, the next time you’re driving up a mountain or simply travelling in your city, and see a Cummins-powered GILLIG battery electric bus, rest assured that it has been through an extensive testing process to ensure safety and reliability. Our customers and communities trust us – and that is something we don’t take lightly.

The Future of Fleets: The four keys to electrification – Part 4

Future of Fleets Zero Emissions

When it comes to battery electric vehicles, there are four keys to adoption within the commercial vehicle sector. In Part 4 of our four-part blog series, we look at the final hurdle a new technology must overcome: Policies and regulation. 

In this fourth preview blog, we look at how policy and regulations regarding commercial EVs must be carefully developed in collaboration with industries and institutions. Sustainability, after all, is not an issue limited to any one sector, and only by drawing on the insight of experts in the technology, infrastructure, and economics of EVs, as well as end-users and other policymakers, will successful incentives to adoption be designed. 

If you are reading this series for the first time, you can find part one here, part two here and part three here. 

Regulatory surety

Finding the right focus will require ongoing conversation, consultation, and collaboration with stakeholders from across the mobility space. The range of routes here is broad: long-term zero-pollution targets will set the overall direction of travel for industry; cross-industry working groups will establish proven technological standards; policies which fund, and remove barriers to, infrastructure rollout will create progress on usability; sustainability stipulations in contracts put out to tender will demonstrate economic viability and create a market for sustainable vehicles; collaborative work on data sharing will improve monitoring and efficiency; and linking tax rates with emissions will improve return-on-investment. 

While the range of options is daunting, there are already examples of best practice emerging across the world. A recent report from the environmental research group Bellona, for example, details the nature of some policy initiatives which are already seeing positive outcomes in construction, which currently accounts for 23% of global carbon dioxide (CO2) emissions.  

In the Norwegian capital of Oslo, for example, the city’s municipal developer has operated a series of initiatives involving setting minimum standards for bidders on contracts it puts out to tender. The developer adopted the policy that ‘what can be run on electric, shall be run on electric’ – creating the potential for a market for electrified construction equipment. Looking ahead, the city anticipates that by 2025 all public construction sites will operate emission-free machinery and transport. 

Part of the success of Oslo’s initiative, besides the determination of stakeholders to make it work, may be in the phrasing of its policy. By using the phrasing ‘what can be run on electric’, the city avoids forcing construction firms into inappropriate adoption (such as electrifying what is not yet suitable to be electrified) and opens a dialogue with them about what can and cannot be electrified, working cooperatively on progress towards sustainability. 

Bringing it all together 

All over the world, progress is being made through hard work to bring the technological capabilities of EVs up to the level where they meet the requirements of commercial applications. 

This requires us to understand their infrastructural requirements and make them clearly actionable, to bring their total cost of ownership down to a level where they compete with and exceed conventional vehicles, and to produce policy which incentivizes their adoption. 

For Cummins, the process of finding the right solution is always a collaborative effort. Getting it right means having conversations across stakeholders in industry and policy, as well as end-users, to deeply understand the issues and ensure successful roll-out.

The Future of Fleets: The four keys to electrification – Part 3

Electrified Power - Future of Fleets - Economic Reality BP 3

When it comes to battery electric vehicles, there are four keys to adoption within the commercial vehicle sector. In Part 3 of our four-part blog series, we look at the third hurdle a new technology must overcome: Economic feasibility. 

 

At present, EVs are often more expensive than their conventionally-powered equivalents. One reason for this is inherent material costs, with battery manufacture requiring large quantities of lithium. Yet, as processes are refined, efficiencies are found, and scale increases, the manufacturing costs of lithium-ion (Li-ion) batteries are expected to reduce – and the reduction of this cost will be a major enabler for early commercial electric vehicles (EVs) adoption.

In this third part of the ‘Future of Fleets’ whitepaper preview series, we look at the economic considerations for electrification. If you are reading this series for the first time, you can find part one here and part two here.

Economic reality 

Today, the economic decision-making involved in purchasing commercial vehicles is familiar to anyone involved in fleet management. It can be broadly divided into capital expenditure (the up-front cost of the vehicle and infrastructure), operating expenses, and the day to day costs of running the vehicle such as fuel and maintenance requirements. 

EV adoption can involve significant outlay, which varies widely depending on application. While the growing availability of on-street charging points can be leveraged for some commercial vehicle fleets, such as last-mile delivery vans, for other applications, such as buses, owned infrastructure is necessary. New electric fleets may, in fact, demand entirely new configurations of buildings. Charging points can however be shared, meaning that the upfront cost can be reduced. In this way, large electrification projects can deliver a better return on investment than smaller projects.  

From an operational perspective, the two main cost areas are energy and maintenance. Energy costs for EVs are dependent on electricity prices, much as fuel costs today are ultimately dependent on oil prices. Maintenance costs may be minimized through the use of telematics to monitor wear and tear and accurately predict when servicing is required. 

While major capital expenditure is clearly involved, through a combination of falling prices over time and efficiency savings from vehicles sharing charging points, EVs can be – and in the case of delivery trucks already are – economically competitive with diesel options.

How does policy and regulation impact electrification of commercial vehicles? Find out in next week’s ‘Future of Fleets’ blog series.
