Transport Evolved 2021 Farewell Comments on EV

Image
Interesting comments: 1. cannot buy EV because cannot charge from home. Solution, solar powered car. 2. more DIY solutions. good opportunity. 3. batteries catching fires. immerse batteries in water. 4. expensive EV. How about us$15,000? 5. Wish to import single cars. Only on private roads. Need to use certified pars and certification costs money. 6. expensive battery. Just use smaller batteries but backed up by supercap. 10 kWh. replaceable and upgradeable. 7. offroad. crumbling roads. need more trucks. The Transparent SUV can carry long items like trucks. Can even do 400kW but only 2 seconds. 8. need solutions for third world to produce EV. Yes, made of plastics and aluminium. Easy to work. But mass production still need to sort out. 9. need sporty car? how about 0-100km/h in 2s? Can turn in a dime also, but no steering or even any gear. Impossible? How about Zero Aerodynamic Drag and Perpetual Motion Engine? My patents had already been granted. Nice to know about the needs of

Electric vehicle (EV) charging standards and how they differ

Let the following serve as a guide, offering all you need to know about the various charging options out there and how they differ.

Chassis for the Transparent SUV

After reading the Autozine article on car chassis, I can describe the chassis design. The flat base can be described as the backbone chassis. We need to make this base very strong but we can use hollow tubes all over the base, leaving a little for the battery case. The battery case can contribute to structural strength by fixing it tightly to the base.  I am thinking of using 1mm thick hollow tubes but at the edges, we need much stronger chassis as crash damage reduction to protect passengers. Also, because the batteries need to be removeable, the edges can only use smaller how tubes, 5 cm width only. We can use thicker aluminium, 5mm even but at places where the Jack's are to be put, we should add steel plates. So the base can be stated as ladder construction, common in SUV except that, the regular flat box design should simplify the ladder structure. Also, all motors are located outside the backbone chassis, not on it. The main problem is how to support the Acrylic exoskeleton. 1

AutoZine Technical School - Chassis

AutoZine Technical School - Chassis Different Types of Chassis Ladder Chassis AC Cobra's chassis. This is the earliest kind of chassis. From the earliest cars until the early 60s, nearly all cars in the world used it as standard. Even in today, most SUVs still employ it. Its construction, indicated by its name, looks like a ladder - two longitudinal rails interconnected by several lateral and cross braces. The longitude members are the main stress member. They deal with the load and also the longitudinal forces caused by acceleration and braking. The lateral and cross members provide resistance to lateral forces and further increase torsional rigidity.    Advantage: Well, it has no much advantage in these days ... it is easy and cheap for hand build, that's all.  Disadvantage: Since it is a 2 dimensional structure, torsional rigidity is very much lower than other chassis, especially when dealing with vertical load or bumps. Who use it ? Most SUVs, classic cars, Lincoln Town Car

DIY Electric Conversions - What about heating and air conditioning?

Aircon for electric vehicles require an integrated motor and compressor unit. Not easy to search at online shopping sites. This video may be 9 years old but the issues are still the same. I am surprised that it was possible to find the integrated motor and compressor for 12 V systems.

1/58th RC Scale Car

The 1/58th body shell can be replaced. Its wheel width is 29 mm just fitting the Transparent SUV 1.7 m width. The wheelbase equivalent is only 2.3 m which is rather short. Even MyVi has a wheelbase of 2.5 m.

Lordstown Motors Wheel Hub Motors

https://www.todaysmotorvehicles.com/article/best-2020-lordstown-motors-wheel-hub-motors/ "Systems integration – Hub-motor-powered EVs will still need traditional friction brakes, and coordinating those with regenerative braking systems in the hub motors will be difficult, especially given the limited real estate inside the wheel." This is wrong. You do not need to put regen electronics inside the wheel. Regen can share the same wire for powering the motor.

The beginner’s guide to crowdfunding - by Sifted

The best because it gives examples unlike Wikipedia. It misses Litigation Finance. https://sifted.eu/articles/startup-crowdfunding/ Startup Life/ Funding/ How To/ The beginner’s guide to crowdfunding Crowdfunding has become a go-to form of fundraising for companies — big and small. Here's what you need to know before you embark on your crowdfunding journey. BY  SIFTED   13 DECEMBER 2019 Crowdfunding has become ubiquitous, the go-to form of fundraising for companies big and small. All of us use  products that successfully raised money via crowdfunding every day  and allow ourselves the occasional chuckle at some of the, ahem,  less  successful campaigns . But, beyond the headlines, there are nuances to be aware of before embarking on your own crowdfunding project. What is crowdfunding? At the risk of stating the obvious, crowdfunding means receiving investments from a large number of individuals (or occasionally groups) to fund a startup or project. In comparison to more traditional
