EV battery standardization discussion

FeaturedA rack serves for an exampleA rack serves for an example

For decades, different laptop manufacturers —any exception?— followed the unethical technique of hiding standard batteries inside pieces of molded plastic, and of course expensive. The result was (is) multiple electronic waste and with it environment hazards for everyone, and tricked users that lost the functionality of a working device for elementary reasons as DC power.

As any company could disappear tomorrow morning, does the EV industry like the game of forcing users to throw away an entire car for the same reasons?

For those individuals that still want to extract money from every corner, let's recall how the air contamination ends in any place nowadays (like your lungs) and it's a senseless act to promote the contamination of your habitat. Quality of life depends on it. That's why someone could doubt about the rationality of some behaviors.

Without more contextual notes, this time the approach will be to discuss thoughts against standardization of EV batteries that are somewhere on the Internet.

The battery must be part of the vehicle structure providing rigidity

Engineering teams have enough tools like cheap materials to achieve more rigidity than ever needed in a ridiculous ratio without battery packs used for it. Using a standard battery space at the bottom, simply the armature of it could serve to provide additional consistence even without battery pack.

It's true that some manufacturers are now obfuscating the battery replacement and the electric vehicle needs specialized technicians for that purpose. The operation is not particularly affordable.

Fortunately, it continues being easy to design an EV with a standard battery space, technology independent, that doesn't have that problem.

The battery is heavy, and it cannot be replaced by a person

While partially true as some people would be capable, this doesn't count as a problem. In other words, nobody extracts the fuel tank and give a walk with it, nor even empty. Service stations and other companies provide mechanisms for fast battery swap or to buy the solution and install it in any location.

The connections for the standard battery cannot withstand the involved stress in continuous swap

Brakes cannot last for a lifetime, nor springs or whatever piece. Anyway, some engineer could develop methods to achieve high efficiency like today some SLR cameras have a built-in cleaner for the sensor. If you ask, numerous individuals will prefer to replace little pieces that throw away the car, break the bank for a new battery pack from the manufacturer in monopoly, or wait for a working recharge in a long trip with time counting as always.

It's already enough with a fast recharging time

Not today, although we agree that someday maybe some technology will achieve a more or less instantaneous charging so the complication is over. Is it? Then, the manufacturer goes out of business and no battery provides unlimited charges. Furthermore, they lose capacity with certain conditions or due to an accident. Right now, with the problem of air pollution, it's better to focus in what is from any perspective useful and it can be done with the state of the art.

A sophisticated, complex design must have its own battery model; like a mobile phone

Different vehicles, wheel size, etc. If you analyze the usual commercial vehicles in the market today, it's really difficult to find one that cannot be enclosed in a standard rectangle from a top view. That doesn't happen with other devices, as they don't have wheels and go for a standard road. The car, in the usual conceptual idea, must have two shafts, one for each two wheels and one for giving it direction. The space in the middle of them looks the more straightforward standardization available, and the unique one for not interfering even with the more complex designs on top of this support armature.

For more than a century, designs were more or less standard for combustion engines. A combustion engine requires a considerable number of pieces, and the design was also limited when the engine was based in real horses.

A motorbike cannot have the standard space

Not every motorbike could, although there are solutions. The main problem in statistical numbers are four wheelers, and even understanding which is the main problem, scooter manufacturers would have their standard without too many worries. Other motorbikes also share a usual space in front of the seat or between the legs. The solution shouldn't be harder though without going sci-fi. Think for instance in a standard and relatively small rectangular battery and a service station that has a directional arm —robotic and with artificial vision is possible— for changing this standard battery. It arrives a particular motorbike that has two of them, so the arm goes and changes the two. The same with tree or whatever, so the manufacturers have the solution to design motorbikes and implement as many batteries as they want. That works for sure!

For standardization, the solution must come from international cooperation in the task of solving the critical consequences created by the insane rate of carbon dioxide emissions, and to protect customers since it's a common solution lately, specially in legislation. Also from democracy, where users demand what's necessary to solve the current environmental crisis and protect current and future generations. And please don't forget that the environment and its diversity is another main subject in the legacy, like we had it.
