A battery-swap mechanism using standard specifications of voltage, amperes hour and battery shape is a must. Then, who buys an EV doesn't depend on a specific battery model nor its specifications, theoretically allowing infinite vehicle lifetime once another standard battery is swapped.
The industry could play other time to close specifications and increase revenue when forces users to acquire a branded battery model. Multiple manufacturers of mobile technology know about this procedure, when they hide standard batteries inside sealed packages that only fit in their devices, with high price and causing thousand tons of electronic waste. They have signed that waste, forcing it, so be it in their conscience and record as Nature's sons.
This time the consequence of proceeding with the non standardization option is especially lamentable because of the critical rate of pollution with brutal levels of toxicity that harm everyone living in the planet, and even future generations.
That's why it's time to demand a non dependent battery model for electric vehicles, soliciting legislation in each country and the creation of a specification from international entities, preferably from well-known ones like the International Organization for Standardization. From ISO:
ISO standards are developed by groups of experts, within technical committees (TCs). TCs are made up of representatives of industry, NGOs, governments and other stakeholders, who are put forward by ISO’s members. Each TC deals with a different subject, for example there are TCs focusing on screw threads, shipping technology, food products and many, many more.
The key factors are, between others:
The electric vehicle guarantees operation for unlimited years.
Installing service stations for standard battery-swap the entire world could be covered as with problematic (in our opinion already archaic) combustion engines.
Any company could enter in the market to provide better specifications and more interesting plans, taking care of the battery quality and maintenance, giving chance to more service stations.
When accessible systems exist to harvest clean (and free) energy installed at houses or buildings at a community level, it appears an option to charge a standard battery while the user utilizes another, having always range even in locations at considerable distance of service stations.
With more competitive players in the market, the price and quality should improve day after day, and that means this time progress and respectable protocols for solving the environmental crisis, finally.
Standard battery specifications are independent of battery technology, so a new development in energy storage simply must respect the usual electricity variables to be launched directly at the market as another option.
It's better in economic and ethical terms to not charge the economical risk of battery restitution to the client. A specialized industry has more technical resources for establishing methods to recycling / refurbish batteries. So this doesn't count as a setback for owners.
Less inherent risks coming from the battery itself, always dangerous without security measures. With due respect to manufacturers, with solid standards the fail statistics should decrease.
The list could be more extensive, although perhaps mentioning aspects of lesser importance.
