Electric vehicle ranges 60 - 132 miles car makers

 

 

EXAMPLES OF EV RANGES - For most users, 100 miles range would allow the shopping run and visits to the folks and friends, without too much of a panic about range limitation. As soon as this range is exceeded, these cars become useless in terms of replacing petrol and diesel cars. What is needed is an infrastructure that replaces the convenience of fossil fuel servicing with the advantages of zero emissions and renewable energy, to create a truly sustainable society in United Nations' terms: SDG 7, 11 and 13.

 

 

 

TESLA & LOTUS - Martin Eberhard, Co-founder of Tesla Motors July 25, 2006 

 

Subject: What exactly is Tesla’s relationship with Lotus? 


Much as Martin Eberhard, co-founder with Marc Tarpenning, and their original investor (also chairman of their board), Elon Musk, love cars they were not automotive engineers.

 

They now have a few excellent automotive engineers at Tesla, some from Lotus, but three years before 2006 they had none.

 

Tesla wanted their first car to handle like a sportscar, so they approached Lotus Cars, known to make some of the finest-handling sports cars on the road. Marc and Martin cornered Roger Becker at the 2004 LA Auto Show and convinced him that Tesla was worthy of consideration.

 

Since that first meeting with Roger Becker, Tesla has built a strong, friendly relationship with the team at Lotus, focused primarily on bringing a great new sporty vehicle to the market quickly and efficiently. Their relationship had several aspects:

 

- Tesla has licensed key technology from Lotus, principally related to structure and safety

 

- Tesla has contracted Lotus Engineering for various engineering and styling jobs

 

- Lotus Cars is contract manufacturer for the Tesla Roadster, with Tesla as supplier to Hethel factory.

 

 

 

 

Technology

 

For those of you who don’t know, the Lotus Elise’s chassis is a work of genius. Richard Rackham’s insight was to construct the entire chassis out of a collection of custom aluminium extrusions that are bonded (glued) together. Bonding instead of welding allows for thinner aluminum as joins have a larger material area to transfer loads between members and avoids material degradation from heating.

 

Some have suggested that the Tesla Roadster is built on a Lotus chassis. This is not strictly true, but yes it is based on it.

 

Tesla licensed the Elise chassis technology, but Tesla’s UK-based chassis team designed the Roadster’s chassis using their technology. The suspension and occupant protection systems are very similar. But here are a few key differences:

 

- Tesla re-engineered the main chassis rail extrusions, making them stronger and thereby allowing lowering of the doorsill height by 2 inches to allow taller drivers. (Elon and Martin are both more than 6’ tall)

 

- Changing chassis rails behind the seats. Lotus simply bends the rails. Tesla miter-cuts the rail, then bonds them together at the correct angle with a custom bracket. This solution was in connection with lowering of the sills, to reduce manufacturing complexity.

 

- They eliminated the box section that surrounds the gas tank on the Elise.

 

- The Tesla Roadster achieves slightly higher stiffness with the structural box that encloses the battery pack.

 

- They designed a unique rear sub-frame, to accommodate a battery pack and electric drivetrain rather than a gas tank, engine, and exhaust system.

 

- They lengthened the Tesla Roadster’s wheelbase by 2 inches – rearward of the seats, giving more room for the battery pack, shifting the weight forward to keep the distribution reasonable, also reducing ride choppiness from the shorter wheelbase.

 

- They beefed up the composite crash structure at the front (a clever Lotus’s innovation) to accommodate the increased weight of the Tesla Roadster. Weight is a Tesla weakness.

 

The suspension components were beefed up to accommodate the increased weight.

 

- They used larger brakes – both front and rear to cope with the additional weight.

 

Tesla engineers extensively modeled the new Tesla chassis starting with Lotus computer models.

 

Tesla also licensed key safety systems from Lotus. This was to save time and money as a shortcut to making a car from nothing. Many suppliers of critical safety systems (principally airbags and ABS brake systems) are geared up to work with very large OEM manufacturers.

 

 

 

 

Engineering and Styling

 

Lotus Engineering principally does engineering and design work for other car companies. Many major car companies have hired Lotus Engineering for some work or other over the years. Tesla hired Lotus Engineering for various bits of analysis, engineering, supply chain help, and body styling.

 

In the beginning, Tesla thought to carry over some of the Elise body panels – because the cost of tooling so many parts when Tesla had practically no money. But Elon Musk (a McLaren F1 owner, had pretty high expectations for the car’s looks) pushed for changes.

 

 

 

 

Manufacturing

 

Lotus Cars is one of the very few companies in the world that has manufactured cars for competitors: the Vauxhall VX-220 and its cousin, the Opel Speedster, were manufactured on the same line that builds the Elise and the Exige. Their assembly line is designed such that they can intersperse different models on the same line – no easy feat. This made them a natural partner for manufacturing. Lotus certainly is not the least expensive car factory in the world, and the exchange rate to the Pound Sterling keeps getting worse, so for us, the Hethel factory is limited as a contract manufacturer only for high-end cars. But they are great partners for the Roadster.

 

 

 

 

 

Tesla's Market Position

 

The Tesla Roadster does indeed carry some Elise DNA. But it is a longer car, designed to deliver a different experience. Tesla are pleased with their friends at Lotus, but their goal was to become a full-blown car manufacturer, with their own factory and a broader product line.

 

 

 

HYDROGEN FUEL CELL CARTRIDGE - It looks like a battery cartridge. It performs like a battery cartridge. It stores energy like a battery cartridge, but it is a hydrogen fuel store and fuel cell cartridge combination. Where lithium and cobalt raw materials may limit the production numbers of EVs as green motoring becomes the norm, hydrogen in a safe format might offer unlimited possibilities. The concept is compatible with SMARTNET FASTCHARGE service stations. NOTE: This is just a concept, not a product yet. More development is needed to before mass production could be entertained.

TESLA S CARTRIDGE EXCHANGE - This concept is not a million miles away from SMARTNET, except that the underground method makes it expensive and complicated. This is a variation of the Better Place system. The point here is that with a bit of tweaking, FASTCHARGE can be made to work in practical terms.
