LEV – Cargo bike collaboration

New Adigo challenge for drivetrain

Adigo has started an inspiring collaboration with Velove in Gothenburg, who develops LEV (Light Electric Vehicles) such as electric cargo bikes and related services, which primarily works as a transport carriage. Mainly for use in major cities across Europe where traffic congestion is high and new emission limits are pushing zero level. This gives their customers a 50% more efficient productivity and 15 times more environmental friendly parcel delivery, which can reach all final destinations better than vans.

The bike operates the last mile to any destination via bike paths, roads, on cobblestones and through narrow paths direct to the customers doorstep. The Velove cargo bike has rear wheel drive and all wheels got separate suspension. The hybrid power comes from your leg muscles and an electric motor as assistance. Adigo are now challenged to see how we can further improve their drivetrain and enable even more productivity for Velove’s customers through our know how in enabling motion.

Voltage Options in Off-Highway Machinery

Voltage Options in Off-Highway Machinery: Unraveling the Low Voltage vs. High Voltage Dilemma

In the fast-paced world of off-highway machinery, the decision between low-voltage and high-voltage systems is a make-or-break factor influencing performance, efficiency, and safety. To navigate this complex terrain successfully, it’s crucial to understand the differences between these two voltage options.

Decoding Low Voltage and High Voltage:

Low-voltage systems are capped at 30Vac or 60Vdc. For lighter off-highway applications, think battery levels of 120Vdc or lower – that’s the low-voltage realm. On the flip side, high-voltage systems, especially prevalent in mining and construction, kick in above 120 volts, sometimes reaching a whopping 1000Vdc or more. So, before settling on a battery voltage, consider the power needs and application requirements.

Advantages of Low Voltage:

Low-voltage systems come with their perks, making them a staple in the off-highway world:

  • Safety First: Lower voltage means lower risks of shocks, arcs, and fires – creating a safer environment for operators and tech wizards.
  • Budget-Friendly: Machines designed for low voltages are usually lighter on the wallet, both initially and in the long run.
  • Reliability Standard: A trusted solution with a proven track record, easily understood by techies and machine operators.
  • Keeping It Simple: Simple design equals easy troubleshooting, repairs, and maintenance – less downtime and fewer expenses.
  • Fun Fact: Did you know? Recent advancements include IPM motor technology for high efficiency in a compact design.

Low-voltage systems commonly power scenarios with a 20 kW cap. Picture electric tractors, utility terrain vehicles, automated guided vehicles – these are the low-voltage champions. But, be wary, their strengths might falter when tackling high-performance, energy-hungry machinery.

Advantages of High Voltage:

High-voltage systems are stealing the spotlight in the off-highway arena, and here’s why:

  • Power Surge: Perfect for heavy-duty machinery, offering more power and efficiency for top-notch productivity.
  • Tech Talk: Allows fancy tech integrations like electric propulsion and regenerative braking, cutting down on fuel consumption and emissions.
  • Future-Proof: Ready to tackle future regulations and environmental standards, setting companies up for the long haul.
  • Efficiency Boost: Less heat loss during energy conversion means an efficiency boost overall.

For the heavy-duty players and fully electric chassis, high voltage is the go-to. Smaller tools that crave less power can either sip directly from the primary high-voltage source or indulge in a DC/DC converter. The choice? It depends on factors like cost, availability, and how complicated you want the integration dance to be.

In a Nutshell:

Choosing between low voltage and high voltage boils down to your specific needs, machine requirements, and safety concerns. While low voltage rocks the reliability boat, high voltage takes the lead in power and keeping up with industry trends.

Hust – Solar Powered Vehicle

Customer: Halmstad University Solar Team (HUST)
Application: Solar Powered Vehicle
Segment: Utility vehicle, Light electric vehicle
Stage of involvement: Idea stage

 

In 2018, while in Jönköping at the Elmia Subcontractor Fair, Adigo was approached by the Halmstad University Solar Team (HUST). They needed assistance in finding the right means of propulsion for a solar powered vehicle they were going to enter in the competition “Bridgestone World Solar Challenge”. Students in 35 countries around the globe compete against each other in a 3000 kilometer trip, to see which solution is the most efficient to gain futures’ fossil-free vehicles.

With HUST we were fortunate enough to enter already at the idea stage, which gave us a great opportunity to really understand the customer’s unique design and needs, in order to create the best possible solution. After some adaptation these solutions were incorporated into the HUST vehicle. The final result was a highly efficient propulsion system which includes a permanent motor and a motor controller built for the specific task of being as potent as could be.

Our Process

Our goal is to get involved in the process as soon as possible, preferably already at the stage of the case study. However, we’re always ready to assist you, no matter how far along you’ve come. Below you can get an insight into what a typical process looks like.

Concept evaluation

  • Pre-study
  • Feasibility

In all aspects of electrification, we begin all design and concept studies based on the user definition and the purpose of the product on the market. We start the process by analyzing our customers’ demands and needs, and together we create an idea based on this. The next step is the pre-study, where we have to take several variables into consideration, such as risk calculations and looking into our customer’s specific needs to see whether the idea is doable or not. We aim to answer all the customers questions in regards to profitability of their product through out the entire lifecycle of their product.

Engineering

  • Project management
  • System design

The next step of the process is the engineering part. This is when it’s time to set up a professional team, the environmental objectives of the project, and start to look for a suitable supplier. When this is done we start to substantiate the idea. The project manager forms a timeline for the project and looks into which types of resources and competences are best fitted for the particular solution. With all the resources in place we start defining the concept, assessing the different components, looking into system and functional design, and in some cases defining the communication between the parts.

Prototyping & Testing

  • Verification
  • Approval

Out of these two steps we will end up with a working prototype. Together with our customer we test the prototype to ensure it upholds its requirements, and if the customer wants, we also do a validation of the product. During this real life test drive we perform both functional, safety standard and lifetime tests. Other aspects may include defining battery technology, comparing the electric motor and regulator as well as estimating the technology level for the entire drive system. It is also important to define the power capacity for maximum use.

Production & Logistics

  • Assembly
  • Traceability

In the fourth step we start to manufacture the quality checked products while following all our standard routines. If needed, we can also perform an end-of-line (EOL) test. This will automatically give you a traceability of all your products. Sometimes, if the solution so requires, we also help to bring out tailor-made packaging for the deliveries. To get your shipment in time, we can handle EDI orders or just make sure to deliver just-in-time (JIT). In Sweden, Adigo accommodates a stock of standard products and subcomponents, for flexibility and fast deliveries.

Support & Updates

  • Follow-up
  • Improvements

We wrap up the process by submitting the final, refined product to the customer and the follow-up work begins. One of our most important goals is to make sure that our customers feel completely secure when putting their valuable ideas in the hands of Adigo. Our mission doesn’t cease just because the hands-on work seems to be done. We are here for follow-ups, product and process improvements, and after market activities, to ensure that our customer feels confident in having Adigo as a long term partner.
