Legislation could force automakers to guarantee a loss of capacity no greater than 30% over 8 years
This is to ensure EV batteries will last for at least the lifetime of the car
The vehicles will have to be fitted with systems that will transmit the battery’s state of charge to the local authorities
The European union is looking to introduce laws that will force automakers to guarantee the batteries of their electric vehicles in specific ways.
The proposed legislation states the batteries should not loose more than 20% of their capacity in the first 5 years or 100,000 kilometers (62,000 miles) and not more than 30% after 8 years or 160,000 kilometers (100,000 miles).
This is similar to the warranty that is already offered by most EV makers, but it will ensure that these companies don’t try to cheap out on the batteries to reduce their vehicle’s cost.
Longer lasting batteries are very important since creating a battery the size of those used in electric vehicles generates a lot of pollution and recycling them is still not entirely figured out.
To ensure this will be respected, the cars will be fitted with remote diagnosis systems that will transmit the state of their batteries to the local authorities via the internet, so vehicles with lower-than-expected battery capacity will be detected.
This initiative is also supported by Canada, China, Japan, South Korea, the United Kingdom and the United States, meaning most countries where electric vehicles are made.
A similar idea was introduced in California in May of this year, but with even stricter rules. This legislation forces batteries to retain at least 80% of their capacity over 15 years and 240,000 kilometers (149,129 miles). A provision for Hydrogen vehicles states they should provide 90% of their initial efficiency after 4,000 hours of driving.
