DIYguru & InNoVaTiOn

DIYguru not only focuses on the static technical knowledge in the domain of EV, but also gives equal attention to the importance of innovation. The domain of innovation would be abridged without the scope of commercialisation. DIYguru addresses the value of these aspects, and aims to work with industrial partners, to incorporate the possibility of innovation labs, incubation support and business models from scratch. While it is essential to work on such innovation labs setup for the EV enthusiast, it is critical to self introspect the technical resources of DIYguru and analyze how our vision and existing resources can channelize the technical knowledge of participants, such that they can initiate and maintain the essence of innovation within themselves, and how their innovation can be directed into an evident business model. The following information below, highlights how the different domains of EV (as covered by DIYguru technical team) would play a critical role in commencing or embarking the sense of innovation within its participants, and how these domains could reinforce our vision or motive of working in the domain of innovation labs and business-oriented incubation.

Vehicle Architecture-

Vehicle Architecture forms the backbone of Electric Vehicle development process. Transition from ICE to EV requires new Chassis platforms which distribute the weight of all new components, lower CG and at the same time can incorporate range of EV models with lower costs. This helps to lower upfront manufacturing costs and needs minimal changes to Vehicle architecture.Few example of such platforms are MEB(Modular Electric drive Matrix  by Volkswagen), Global EV platform from GM,eTNGA(Toyota Electric New Generation Architecture )CMF(Common Modular Family) architecture from Renault-Nissan and e-GMP(Global Modular platform ) from KIA. Though the initial investment is high but with lot of cost saving potentials as turn around time for developing new vehicles is reduced.

Innovation Capability- 

DIYguru Course offers a basic understanding of all components Making up an EV. Our aim is to foster innovation and trigger innovative mindset with variety of students from different background undertaking these courses. With Vehicle architecture, one can think of the Location of Components such as Battery, Motors in such a way that it can enable either Rear or Front or All-wheel drive vehicles. For this simulation of vehicles, Load distribution is necessary. Along with which how these architectures can host a range of Battery packs sizes and motor components with minimal changes can lead to the integration of  different vehicle families on the same architecture.DIY guru courses offer Simulation and Analysis  courses where students can learn to optimize different EV components.With various hands-on projects, students get an opportunity to channel their thoughts to the product development process by presenting various Weight optimizing options pertaining to components placed on EV architectures. This is not only limited to the location of Batteries and Electric motors but also finalizing which battery cells to use, motors to select, and integration of these components towards the product development process.

Vehicle Dynamics- 

Since Electric power trains have started becoming commercially available their impact on vehicle performance has become equally important.The integration of Electric power train with Vehicle dynamics and control systems is going to be an important area of research.This integration can be discussed in terms of Roll,Pitch and Yaw plane of vehicle as all these are couples planes and impact Ride ,Handling and Stability Performance of the vehicle.Similarly, energy regeneration/consumption capability is also coupled with Vehicle dynamics and controls.In future transportation technologies integration of controlled subsystems which were earlier independent and open-loop will become closed loop ( e.g.Cruise control will pave way for Adaptive cruise control ).The key component which connects electric  vehicle performance with vehicle dynamics is an electric motor.

Innovation opportunities

Electric motors have three basic performance attributes.

1) Responsive to torque or speed demand

2) Reversible – works as motor or generator

3) Energy efficiency is more than 90%

DIYguru EV  courses offer a deep dive into electric motor technologies and control.The students work on modeling and analysis of Motors in softwares such as Ansys or MATLAB to analyze its performance from different aspects.Another area of innovation in vehicle dynamics is controlling vehicle motion using torque vectoring.This replaces traditional differentials with individual motors mounted on each wheel to control torque output.This opens a huge opportunity for innovative minds to analyze how vehicle will react to torque change and how it affects dynamics stability of vehicle.DIY guru offers Fundamental of vehicle dynamics course which presents an opportunity to understand different dynamic aspects of vehicles.Here we have discussed only about one technology.Similar to this there are multiple areas such as Vehicle Braking and regeneration ,Integration of different sensors for Longitudinal and Lateral control of vehicle such as Lidar,Camera,Radar and how it helps vehicle either maintain lanes or give alerts or stops vehicle automatically based on the obstacle.Many such technologies will be there on EVs and offer tremendous research scope for candidates.The truth is the future is going to CASE where C-Connected (technologies) A-Autonomous S-Shared and E is Electric mobility and in each of these technology, Vehicle Dynamics has huge role to explore tremendous opportunities in terms of SiL,HiL technologies.Future is truly Electric.

Battery Management System,  Energy Production & Storage.

Energy storage is an important concept while designing an Electric vehicle. It’s the powerhouse of the whole machine that gives energy to each and every system present in the vehicle. The Modern Electric cars and bikes come with Lithium ion battery packs which are made up of combination and configuration of hundreds and thousands of Lithium ion cells of different construction and chemistries. Each and every cell needs to be monitored and quantified for the optimum performance of the battery.

DIYguru briefs and procures the necessity of technology required for battery design and monitoring. The Battery Management system (BMS) course is based on the complete walk around of BMS used in a four-wheeler.

The understanding of BMS and battery pack design will stronghold the energy storage management and regeneration of the energy consumed by the vehicle. The selection of proper cells, cell balancing, combination and thermal management will make a safe and economic battery pack with high energy rating. 

    

Powertrain:

When climate change is the main concern, the atmost sustainability is needed in the field of automotive industry in term of fossil fuel combustion, where Electric Vehicle with shortened acronym as EV took the important alternate option.  In this transition of ICEV to pure EV [The only propulsion is provided by motor from a single energy source electricity] the Hybrid vehicle took birth [ propulsion energy is supplied from different energy sources].

With the unveiling of the National Electric Mobility Mission Plan 2020, manufacturers are adopting electric vehicles in an attempt to reduce our dependence on imported oil. The ambitious plan aims to produce 6-7 million electric vehicles by 2020 with an estimated fuel savings of 2.2-2.5 million tons. Vehicle manufacturers in India have a tough road ahead in meeting this goal and tailoring electric vehicles for the Indian market.

The global low-speed vehicle market is projected to grow at a CAGR of 8.6% to reach a market size of USD 6.3 billion by 2025 from 4.2 billion in 2020. The global low speed electric vehicle market was valued at $2,395.8 million in 2017, and is projected to reach $7,617.3 million by 2025, registering a CAGR of 15.4% from 2018 to 2025.The key factors driving the global low-speed vehicle market are increasing  the rising trend of using LSV in gated communities, hotels & resorts, industrial facilities, golf courses & college campuses.

DIYguru understands the Role Of Soft Skills in Innovation & Incubation

We’re aware of the criticality of the hard skills that are required by the professionals to excel in their domain be it technical or not. As hard skills are the very core of your daily work and considering that is your expertise.

What we somehow miss is the required emphasis on the soft skills that professionals must equip themselves with in order to excel in their fields irrespective of the domain they belong to. Today, we’ll understand how crucial it is to have the right soft skills to excel in the technical fields, but before that we shall get a glimpse on what all comprises in the soft skills.

Soft Skills and their Importance

Soft skills are skills which deal with communicating with the people around, having a sense of emotional intelligence, and such. Some of the crucial soft skills and its impact which shall be ingrained by the professionals are as follows:

Critical Thinking: It is the ability to cerebrally analyze and conceptualize while absorbing information. 

Public Speaking: It is the act of delivering information to the audience effectively.

Emotional Intelligence: It is an art of perceiving and handling emotions in the right manner.

Teamwork: It is when a group of members jointly perform a task that has  a compounded effect.

Interpersonal Relation: This involves how good your relationship is with several people involved.

Problem Solving Skills: The process through which an individual solves a given problem through the right approach.

Leadership Skills: It encompasses an individual’s ability to lead. It could be a group, work, initiative, or organization.

Flexibility: It is an individual’s ability to stay agile in a given situation almost instantly and effortlessly.

Decision Making: It reflects the capability of  a person in taking the right decision through a structured approach while effectively analyzing the given situation. 

Conflict Management: It demonstrates an individual’s ability to resolve conflicts through sound listening and effective decisions after a thorough analysis.

Every professional shall inculcate the given soft skills to better express themselves and their work.

How soft skills help Innovation and Incubation 

Innovation is referred to as the creation of something new, it could be a process, a product, or any services. On a similar line, Incubation is to provide an environment to favorably develop something. 

So, when we talk about incubation in terms of startups, then that refers to the incubators that support the growth of a startup. Startups receive following supports through incubators by providing:

Partnership opportunities

Funding avenues,

Mentoring assistance, 

Operational allowances, and so on.

It’s apparent that a certain level of innovation is always present in  any startup as startups are known to be backed up by innovations and therefore require incubation support to further flourish and grow. Therefore, innovation and incubation go hand in hand.

Let’s explore different scenarios where the importance of soft skills is amplified in various ways such as:

When we talk about startups looking for partners to collaborate with, one has to reflect the teamwork skills the employees have, the leadership skills that one possesses, and sharing the concept of their work with their vision and mission in the most effective manner. So, despite having the best innovations ingrained in your products and services, you might end up with fewer partnership opportunities and therefore resulting in a threat to your funding avenues as well.

When looking for mentoring assistance from the leaders across the corporate world or some monetary assistance required for your current engagements, it is always important to master up your soft skills to better present your work and establish worthy credibility to all your stakeholders involved.

Retrofication

In automobile engineering, Retrofication is the replacement of a car’s combustion engine and connected components with an electric motor and batteries, to create an all-electric vehicle. 

This method is being used extensively in Europe to convert diesel trucks and buses into zero-emission CVs as it has helped reduce carbon emissions within big cities while also reducing congestion.

In 1993, India’s first three CNG stations were opened in Delhi for private and commercial vehicles. In1998 decision by the Supreme Court of India to phase out diesel buses from the roads of Delhi. The then-record levels of pollutants in the air compelled the Supreme Court to grant relief to the citizens. The bench proposed that the highly polluting buses be either taken off the roads or the diesel engine be replaced with a cleaner alternative. Retrofit it with Compressed Natural Gas (CNG). This policy decision enabled the successful conversion of more than 30 lakh vehicles to CNG.  Now, let’s jump back to the present day. Even though the amount of emissions per vehicle is decreasing due to improvements in technology, pollution levels are rising once again as the number of vehicles is increasing to meet the growing population. In such a situation, a similar policy can be expected from the government. A similar wave is fast reaching the shores of our nation again and this time it is retrofitting commercial vehicles into 100% electric. 

Not one, not two, But many benefits of vehicle electrification. 

1:- Reduce the emissions of vehicles that are already on the road, as electric vehicles do not produce any emissions themselves.

2:- Reduce operations cost as the cost of electricity per km is significantly less when compared to petrol or diesel

3:- Reduce the vast amount of waste created when cars reach the end of their lifecycle – as older cars or those written off after a road traffic accident are typically scrapped. This creates a considerable amount of metal, plastic and fabric waste, and uses a large amount of energy to recycle discarded parts into useful materials.

4:- The maintenance cost of an Electric vehicle is considerably less than that of an ICE vehicle

How to Retrofication

Now that we know what retrofitting is, we can now learn what is needed to retrofit your vehicle. 

The 1st step:-  Make sure that vehicle’s internal components are working or not? Elements such as the transmission shaft must not be broken or cracked.

 The 2nd step:- Remove all ICE-related hardware. Including engine, fuel tank, muffler, exhaust, starter, and radiator. They will be replaced by myriad components, the most important of which is the electric motor. The size of the motor used will depend primarily on the size of the vehicle, expected performance, and weight.

The 3rd step:- The battery pack, the powerhouse of electric vehicles. One would need to decide between a lead-acid battery and a lithium-ion battery. Lead-acid batteries used in golf carts are often installed, although they generally provide a slim operating range on a single charge.

The 4th step:- lithium cells, which are smaller and lighter and can enable longer ranges but are more expensive and require more protection electronics on board. How many batteries will be required will depend on the vehicle and the available space in which they are to be fitted. You’ll also need a power controller to regulate the flow of energy between the battery and the motor, a charging system to replenish the batteries via an electric circuit, wiring harnesses, and myriad other components. 

The total cost will depend on the vehicle you’re modifying, the range, and the type of performance you’re expecting.

An EV Conversion kit includes? 

  • Motor
  • Controller
  • Shunt
  • Transmission adapter kit
  • Charger 
  • Chill plate
  • DC/DC converter
  • Throttle controller
  • Controller mount. 

DIYguru very well understands the role of retrofitted EVs in the ever-changing market of EV industries, and to support this evolving advancement, DIYguru is now launching the MAKERS CAMPAIGN 3.0. The Makers campaign of DIYguru has been one of our identities, as DIYguru initiated its operation with Campaign 1.0. Continuing this progress, the Campaign 3.0 has the capability to help the EV evolution in India and greatly focuses on the domain of EV retrofitting. More details are given below at the end of this document.
