I am against demolishing the old cars and we are working on developing EV conversion kits to use these vehicles. Any low cost suggestion to convert these vehicles are welcome.

Of course, modifying and upgrading the existing ICE-based vehicles would be less expensive and more acceptable. To do so, I think a conversion kit including the electric motor and motor drive would be sufficient as John denoted. However, from the performance perspective, I believe some EV parts must be redesigned to achieve optimum operating condition. For instance, the body weight should be reduced using ultralight materials to optimize the energy consumption and increase the battery lifetime. In developing countries, this could be fulfilled in both ways, either gradually upgrading the existing cars or manufacturing new EVs.

In response to John's Comment,

The most important challenges is to find optimized, cheap and easily assembled kits.

The farest thing to do for the developing countries is to encourage them with a gradual change-over programme, which involves developing conversion kits for the exixting vehicles on the road, in addition, helping them to develope the capabilities/technologies necessary for complete conversion over a period of time. Majority of the developing countries have fossil resources to continue to run the existing vehicles for another ecaded to come. Demolishing the existing vehicles will cause them huge disruptions and economic losses.

Propulsion system is only one function among many. Another is safety. Vehicles are designed to absorb energy and protect occupant in crash. Powertrain substitution changes that signature. Not kit developper has the means to economically recertify existing vehicles for safety. Better let them rust away and bring in updated product.

A more fundamental question is the competency of the technology forcing regulators. Easier to encourage technology than to direct science or economy. Why the EV mandate? Don't we have other technical solutions to help whatever these objectives are? Hydraulic hybrids may be both a better OEM solution, and conversion opportunity to improve existing fleet fuel economy and toxic emissions. My bet is that along side ICE & EV we will see other innovative solutions including hydraulic.

As far as I know, third world countries are not pushing for totally electrifying their automotive sector like the developed countries. In many cases, they do not have enough electricity generating capability to meet the existing load, and the situation will be worsened with more EVs on the road. So such countries are less likely to dump the conventional vehicles soon.

But conversion of conventional vehicles is taking place of course. Here in Bangladesh, we are seeing that in a bit differently than you have stated. These days, we have lots of motor-driven rickshaws, bicycles, and motorcycles. They are using the cheap lead-acid batteries rather than the EV standard Li-ions - so it is far from the R&D results of car companies. These improvised transports are mostly illegal too.

The reason why all the major manufacturers are turning to EV is that it has managed to project itself as the future of transportation, and not investing in it means losing market, competitiveness, and profit - thus resulting into extinction. In terms of performance, EVs can generate torque and power which the ICEs can hardly match - so racing with them is attractive. Racing is also a way to develop the vehicle technology - hence the interest of the automotive world in it alongside the huge R&D investments.

Getting back to the question, third world countries may not force people to abandon the conventional vehicles anytime soon. And conversion is very likely with cheap materials. Car mechanics are very resourceful (take Cuba for example), and they are very much likely to pull off this feat too.

I think that the future is for cars that do not use hydrocarbons, but now this is a premature idea........

Здравейте, според прехода към електрически превозни средствамен преминава първо през хибридните превозно средства. Трябва да се обърне вниманиет върху това електрическите батерии в хибридните автомобили да могат да съхраняват колкото се може повече акумулирана енергия. Другата важна особенност е електрическите батерии трябва да се създават с по-голям капацитет и с възможност за бързо зареждане. Това за момента са най-неоходимите проблеми на хибридните автомобили. и след това идват напълно електрическите автомобили. средства менприе, че за решаван.

I think the world is changing rapidly. We can not answer these questions categorically, because we do not know much. We can only consider the problem in the short term. I do not have a specific answer to this question.

Наистина, светът на превозните средства се променя динамично и трябва да реагираме адекватно.

An electric car entirely means the weight of the vehicle becomes lighter, to be comfortably controlled and safe must of course have a proportional weight for vehicles traveling on the highway. for it to be recalculated sprung and unsprung weight it and this means there must be a new design. the old car is certainly not good to be modified to all electric.

Hi

considering the effect of old cars on the nature and safe

Hi

considering the effect of cars currently in use, on the health of nature and humans, it is clear and all peaple should try without regards to considerations other than health, to construct electrical cars. The experience with cell phons is a good reason for this idea.
