E-karts, a motorsporting challenge

History
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 – E-MOTORSPORT

New challenges in motorsport

Every year, confidence in internal combustion engines decreases when improvements in the performance of battery and electric motor technology achieve potential equality. This new comparison also means that the trend for motorsport chooses the more environmentally friendly alternative and at the same time you get a different type of fast-paced experience.

Although most motorsport fans are not yet ready to switch petrol to battery cells, but it is now impossible to ignore the large amount of new and exciting racing events that use all the electric power. Electric propulsion offers enormous development potential in motorsport and can inspire people to choose more innovative electric propulsion.

The environmental pressure has led to the introduction of smaller, more efficient, turbocharged engines in the competition arenas, while hybrid and all-electric vehicles are also increasing sharply. Over the past year, all rechargeable vehicles have increased by 33% in Sweden and has passed the amount by 137000 vehicles compared to the global amount of 7,5M BEV (Batterydriven) and PHEV (Hybrid) increase of 31%, where China represents almost half of it.

Today’s championships are divided into four categories

Todays investors
The largest investments today in e-motorsport are made in Formula E. Partly through the major motor manufacturers and other sponsors but also in collaboration with the UN’s environmental program. It will increase awareness of air pollution and the benefits of electrical mobility when competing in the heart of some of the world’s most iconic cities across five continents, which also gives a wider audience. Most of the drivers has started to compete with a fuel vehicle and experience that the electric motors provide more power and a different type of challenge.

Among many experienced drivers, the Swedish Grandmaster Mattias Ekström has been elected ambassador to participate in CUPRA e-racing. After a career dedicated to the racing world where he investigated all internal combustion engine formats, he now wants to move to electric racing, which has been his goal in this segment since its creation.

Can e-motorsport be sustainable in the long run?
Let us imagine that we can keep all the attractions that make cars and motorcycle races a unique experience but without polluting fossil fuels and with much lower noise levels. At the same time be able to attract investment and research in technology and ultimately produce the same adrenaline, controlled risk and speed challenges.

Will the desire for range meet the needs of the future?
One of the greatest consumer concerns regarding electric vehicles is the distance they can travel on a single charge, as suggested by respondents to surveys made in Europe. Today however, the Tesla Roadstar can already exceed 1000 km and as battery technology continues to improve, the projected average range of electric vehicles is expected to reach up to 450 km by 2030 compared to today’s approximately 300 km.

How does the future of e-motorsport look?
E-motorsports are far developed but not yet near the finish line and will certainly become more common in the future as fuel-powered competitions decrease as emission requirements become increasingly stricter. Many new types of racing vehicles are being developed and are now tested for approval, such as go-karting and motocross. The sponsors are keen to be involved and show their support for the development.

Adigo are eager to help you choose the most suitable products for your project, depending on demands set by the application. Since efficiency is key in most battery-powered vehicles can we offer high performance motors in different sizes and powers.

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.

Parameters:
– 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!

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.
