Electric Cars Will Have to Display Battery Health Under New Proposed Guidelines in Japan

 

Electric cars are forcing their way into the mainstream, highly sought after due to their preferable environmental impact in comparison to traditional cars. However, as with all electrical items which are battery powered, their batteries inevitably deteriorate over time. This poses a new problem for our environment if they are discarded and not reused. 

In addition to this, the manufacturing of electric cars produces a large carbon footprint, so the resale of these on the used car market needs to be encouraged as much as possible. 

With new proposed guidelines, Japan is aiming to try and help with both of these issues. 

It will soon be mandatory for electric vehicles to indicate how much charge they can still hold, under proposed guidelines being drawn up for car-makers by the Japanese government.

By ensuring that battery health is displayed within every electric car, it is hoped that this will help with determining the resale value of a vehicle, or of the batteries potential value to the e-waste recycling industry. 

Battery life is one of the biggest worries that potential buyers of electric cars have, so knowing the exact condition of the health of the battery might give them more confidence to buy one. Furthermore, this will inform electric vehicle owners when their car battery is deteriorating, so that they can take it to be serviced and the battery can be removed and properly recycled. 

 

The Deterioration of Electric Car Batteries 

 

Electric car batteries degrade over time due to extended use. The cycle of charge (when you plug the car in) and discharge (when you drive the car) takes a toll on the capacity of the vehicle. 

Overcharging can cause chemical changes which negatively impact how a battery works. Similarly, heavily draining the battery is not good either. It is recommended to keep the battery operating between 50% and 80% charge, rather than to top it up to 100% or to let it go down as low as 20%. 

 

When Will These Battery Health Gauges Be Introduced? 

 

Currently, the Nissan Leaf is the only electric car which offers a battery health indicator. However, this is set to soon change. The draft guidelines by the Japanese government will be unveiled in September and could be finalised before the end of 2019. 

Electric car manufacturers will likely welcome the news positively, as it is another step towards bringing electric vehicles into widespread use. The gauge will show charge capacity relative to when the car was purchased.

 

E-Waste World Conference & Expo will take place from Thursday 14 November to Friday 15 November at the Kap Europa, Frankfurt Messe, Germany.
