E-karts, a motorsporting challenge

Our customer Caroli develops and sells go-karts for the rental market. Since 2004 they have worked with electric karts and are the only Swedish company that manufactures them, and they are still running… lap after lap! Adigo got involved in an early stage and has tested out and developed a custom ventilated, brushless motor with control that can withstand the strain of a rental kart. As resulted in a compact, flexible motor with high efficiency, low weight and with a long lifecycle.

Today there are a total of approx. 85-90 tracks in Sweden, of which 30% are indoor courses. Caroli covers over 70% of all electric go-kart tracks in Sweden, and 60% of all electric go-kart tracks in Denmark, Norway and Sweden combined!

Facts compared
The rental kart is much more robust and durable than a racing-kart, which may be self-evident as many different types of ages and drivers rent the same go-kart. The rental kart has 10-15Hp which makes approx. 70km/h. The racing-kart has 30-40Hp and can drive twice as fast and weighs half as much and thus more fragile.

What is the strength about your e-kart compared to your competitors?
The strength lies in our modular thinking around all electrical components that can be easily replaced with ready-made separated modular systems. ChargingThe electrical system is so safe that no components can be installed incorrectly. A default component is replaced as easily as the seat belt is adjusted.
Beyond the electronics, the driving-sense itself is unique, very similar to a racing-kart. With an increased flexibility in the chassis together with improved crash protection, this contributes to better grip and an optimal racing emotion.

How does the future look with e-karting?
Today, when starting a new rental site there is a demand that only e-karts are approved, so the future looks bright. Talking about the e-cart Championship is only at a start-up level and hopefully running in the nearest future.

Adigo Insight – Material Handling

Material handling plays an important role within manufacturing and logistics. Almost every item of physical commerce has been transported on a conveyor or lift truck or other type of material handling equipment in manufacturing plants, warehouses, and retail stores. Today’s logistics processes place increased demands on both machines and drivers. The loads become heavier and the lift heights higher, while at the same time logistics needs to be streamlined. High productivity and availability create profitability throughout the logistics chain. Material handling is usually required as part of every production worker’s job. It is used in a wide range of manual, semi-automated and autonomous material handling equipment which all includes consideration of the protection, safety, storage and control of materials throughout their manufacturing,warehousing, distribution, consumption, and disposal.

Criteria such as ergonomic, efficiency and utilization time is something Adigo manage in a daily basis with focus on improving the interaction between man and technology. In terms of user requirements, innovations have been developed that helps the driver to increase both comfort and safety also for minimizing the risk of accidents. Accidents not only involve the risk of personal injury or legal consequences, it can also result in high costs due to downtime, lost productivity or delayed deliveries.

Driverless logistics
The trend in logistics is towards more driverless technology. The technology for automatic warehouse or lean technology transports has reached maturity in most businesses. The challenge is to be able to take the necessary steps and provide the conditions for this kind of transport. Mobile robots solve labor and safety issues. Statistics from 2013 tells that 800 people only in Sweden were injured so much that they are away from work.

Driverless trucks or AGV’s as they are called, came already in the 1980s when Volvo had a major impact for the industry. They started up implementing a magnetic loop in the floor that the truck could follow. Should the route be changed, it was only to pick up the concrete saw.

In the 2000’s, laser navigation came, which can be described as a reverse GPS system where trucks are controlled via reflectors.

This is a customer solution by Flexqube, handling material for varios warehouses.Today, the robots communicate with each other through a radio-based mesh network (Industrial VLAN) to reduce picking times and risks of injuries. These Autonomous material handling systems at the right place is a cost-effective solution and can be used in lean-development to shift from random truck driving to time-based supply systems and timed flows. It also places higher demands on the organization, for example around standardized working methods and robust processes. If one robot breaks down, another takes over its tasks. The vehicles move more slowly, they do not wear out as hard as manual trucks, which means longer durability and lower maintenance. With IoT integrated delivery monitoring or Fleet Management, high demands are placed on accuracy and gives the end customer good efficiency planning.

These pictures are a customer solution by FlexQube, they uses vision technology that follows color and contrast with paint or tape. This method makes it easy to install and change if needed. See their eQart in motion here

All Adigo solutions include consulting, concept studies, project implementation, customer service, best-in-class technologies and software, all tailored to the specific requirements needed for your business.

A bright future for electrified machines

Adigo Insight / EUV
– Soil Compaction Machines –

The higher demands on lower or Zero emission of CO2 opens up a hole new market for the smaller Electric utility vehicles. These new emission levels narrows in fast for the construction industry where todays machines quite fast need to adapt to be accepted already year 2025 in some European citys.

Our customer Swepac are developing and manufacturing machines for soil compaction with many years of experience from delivering vibratory plates to the rental industry. Many of their machines are built today with small petrol/diesel engines, creating discomfort in both work environment and atmosphere. These ICE engines create noise and exhaust that needs to be reduced or stopped by replacement of new much cleaner thus quieter engines.

Adigo got involved early in this new development era  together with Swepac, we developed a whole new generation of electrified equipment for this kind of ground preparation work. Adigo optimized the functionality and made it fit in the current design, programmed the system to get an efficient propulsion.

Through component evaluation, real drivelines tests to gain the maximum effect and by final approval  the result became successful. This turnes-out to be highly sustainable products with a good balance of efficiency and reliability to many of their machines. This development of the electrified machine also resulted in the world’s first cloud connected soil compactor fleet, with several user advantages such as GPS tracking, vibration exposure with live-logging and optimized service intervals and also tracking of stolen machines.


Our collaboration is just the beginning of Swepac’s journey towards becoming a conscious low-impact business. We are now looking into possibilities of further development of Swepac’s remaining assortment.

Probably many more companies will have to follow this trend.
What’s your company’s future challenge in electrification of low-carbon machines?

Adigo stands eager to help you adapt your product for new market demands!

Adigo Insight – Electric Utility Vehicle

The future emission work has already started

Electrification of the Heavy-duty vehicles and the demand from the end-customers is growing. Today lorries, buses and coaches are responsible for about a quarter of CO² emissions from road transport in the EU and for some 6% of total EU emissions. Despite some improvements in fuel consumption efficiency in recent years, these emissions are still rising, mainly due to increasing road freight traffic.

From 2025 on, manufacturers will have to meet the targets set for the fleet-wide average CO² emissions of their new lorries registered in a given calendar year. Stricter targets will start applying from 2030 on. The targets are expressed as a percentage reduction of emissions compared to EU average in the reference period (1 July 2019–30 June 2020):
* from 2025 onwards: 15% reduction
* from 2030 onwards: 30% reduction

Setting Course for 2025

Can Oslo and Amsterdam meet the environmental demands for 2025?
Norway’s main parties appear to have agreed on the fate of the internal combustion engine. Together with Netherlands who also is a part of the ZEV organization, The International Zero-Emission Vehicle Alliance there will be prohibition applied for the new sale of cars with gasoline or diesel engines in 2025. With Oslo’s and Amsterdam’s rapid growth, the scarcity of energy, and the importance of a healthy living environment, the need for cleaner, more energy-efficient vehicles is greater than ever. The question is, will this short time suffice?

For passenger cars it’s partly solved but how will this affect the EUV vehicles? Many heavy-duty vehicles also have the environmental requirements. A typical EUV in the cities primarily are building roads, ground facility, excavation and other roadworks. Here is a larger challenge where a few manufacturers just started their trip towards electrification. Does the market have the knowledge in replacing the combustion engine with an electrical drive-chain, adding functional power and motor controls to fit the requirements. Many functions vehicles have will also be replaced with electromechanical components.

Classification of Electric Vehicles
If the vehicle weighs from 300kg it fits into a standard in below chart as an EUV. Categorize L, M and N. The European Commision classifies vehicles as part of emission standards and other vehicle regulations. Two directives of the European Parliament and of the Council serve sources for these definitions and classifications
(2013/168/2019 of 20-Feb-2019 and 2007/46/2019/EC of 01-Sept-2019) Source: https://eur-lex.europa.eu/homepage.html

What aspects are to be considered for getting there in 5 years?

  1. Technical requirements
    The market for commercial electric vehicle projects involves designing a high speed and high power electric motor that would be used with a gearbox. To design the entire electric powertrain of larger four-wheeled vehicles weighing from 300 kg up to several tons you need to know the defined environment that it will be operating in to choose which parts are involved to electrify this vehicle. It applies aspects such as engine and controller comparisons, estimated technology level of entire system. Is it a direct-drive in-wheel, transaxle or hub motors, do you need to replace with other components when you’re changing the drive-system? What kind of power source will be needed to run the vehicle?
  1. Efficiency
    The customers need could be a more specific propulsion unit that must be adapted to different external conditions and aims to reach a high efficiency. A gearbox can be part of the solution when it comes to increasing efficiency of a powertrain or a combination of hub motors and transaxles, how can this be integrated without changing too much in the driveline. While the peak efficiency of the AC Induction motors can be as high as PMDC motors, the high efficiency can only be maintained at a certain operating spot. This should also set into the entire drive cycle analysis and choice of technology in the drivetrain. The variations of drivetrains that will be the solutions on the EUV market will be greatly diverse and highly specific to the area of use for the vehicle.
  1. Design
    Another requirement that often arises is the fitting of the components in confined/given spaces. The bus and trucks OEM’s rarely want to do changes in their vehicles or in their production lines, simply for the purpose of incorporating a new powertrain. Direct-drive in-wheel or hub motors or transaxles, on the other end, often require a special axle or the customization of other vehicle parts in order to be properly integrated. Fitting as much battery into the current chassis is already quite a challenge. When such an EUV OEM company shall design or redesign such a chassis they need to entirely use a new engineering pattern and process from how they are used to and ask questions never asked in their organizations.
  1. Usability vs Power source
    In order to optimize the batteries for the perfect combination of vehicle propulsion and performance with a maximized user time, you also need to consider the total energy consumption. Today you take your vehicle to the gas station but how will we accomplish this change with upcoming technology? When, how and where will you get your vehicle charged, will it be made slowly during night-time or a fast charged during your lunch break? We do understand that it is a challenge and that the infrastructure must be updated with this technology. But with the right expertise in development, this will be solved in the best way.
  1. Maintainance
    There are many advantages using electric vehicles, but of course there is a maintenance cost, as with other vehicles. Maintenance is also about being able to access, diagnose and replace a product as easy as possible when a problem occurs. A motor system integrated with multiple other components such as a gearbox assembly or inside a wheel might be hard to access on a standalone basis. Such scenarios can make maintenance more complex or costly. Despite this, it is a selling point-in-favor of EUV’s as the costs in relation to ordinary vehicles are expected to decrease.

Adigo Insight -Light Electric Vehicles

LEV – How to electrify small vehicles?

In all aspects of electrification, we begin all design and concept studies based on the user definition and the purpose of the vehicle in the market. In very rare cases the designs starts from the technical side but rather the business models for the customers product. In below text we will try to give you the insights we have gathered since the mid 70’s about electrification.

The Electric Vehicle Market is projected to reach 27 million units by 2030 from an estimated 3 million units in 2019, at a CAGR (Compound annual growth) of 21.1%. The European market is projected to experience steady growth, owing to a well-developed infrastructure for electric vehicles.

If the vehicle weights up to 300kg in dry weight it fits into a standard in below chart as an LEV (Light Electric Vehicle) L1e – L4e.

Source; L-category vehicles classification according Reg. 168 -Annex I, European Parliament

When we are engaged in a LEV product we work out of a fixed project structure to ensure optimal outcom in every project. We do a business environmental check consisting of questions like below.

– How will this product be sold?
– What purpose does the product fulfil the market?
– How does the financial business model look from the customers perspective?
– Products time of use?
– The defined environment that it will be operated in
– Effects from external environment
– ….and some more aspect taken into calculations……

The concept study concerns the ability to build a realistic vehicle that fits into the customers business model. Can it be feasaible to build and produce such powertrain for this vehicle? We aim to answer all the customers questions in regards to profitability of their product through out the entire lifecycle of their product. Further questions to take into count;
– Expected acceleration and torque
– Surface that may occur in the usage
– Flat ground or hills, or if both combined

Using our Calculation tools for simulating how to build the blocks for the vehicles electric powertrain defines the basis for this concept study. Questions concerned will be such as:
– Use of energy and how to balance battery pack
– Need for torque and how it is utilised in the best way
– Conclusion that compares expectations to technical limitations
– Outlined aspects in feedback to vehicle design department

Last step will for sure be the technical nerdy part of the agenda (yes, we love it!!!). It concerns aspects as battery technology, motor and controller comparisons, estimated technology level of entire system in regards to business values and of course government laws and regulations.

Looking into the above sections we work similar with all our customer cases whether it is a bicycle, electric sports vehicle or a simple/complex human transportation. The only aspect that keeps them all in the same frame of mind is the energy capacity to maximize usage in small electric vehicles.

Adigo most certainly would like to help you to develop your next LEV or next generation of existing LEV!
