Batteries in electric cars can last a long time

A key part of electric cars is the battery. Who will be the winner in the big market race depends on their development and from the user's point of view there are also many main topics. We will single out the two most important ones, price and durability.

Prices will come down and there don't seem to be too many sustainability issues. A new study by scientists from the SLAC-Stanford Battery Center suggests that electric vehicle batteries may last significantly longer than previously expected.

SLAC points out that the way battery life cycles are calculated is not good when it comes to electric vehicles. This is because they assume a fairly constant cycle of discharging and recharging, which does not happen in everyday use.

The energy cycles of electric vehicles are much more complex, it all depends on the driving style and location, city driving, driving on roads outside cities, highways. Charging varies as some owners may charge the battery every night, while others may wait days between charges.

The scientists tried to simulate real conditions during battery testing and created four charge/discharge profiles. They tested 92 commercial lithium-ion batteries over two years and found that the more realistic the profile, the longer the lifespan of electric vehicles.

The study revealed several surprises, including that a sudden and brief acceleration can lead to a slower degradation. A study has shown that braking and resting regenerative batteries helps them last longer.

There are also significant differences between time, ie battery age and charge cycles, when it comes to battery aging. Cycles are most important for electric vehicles that are constantly in use, such as taxis, buses and delivery vehicles. The bottom line is that batteries can last 40 percent longer than predicted. /Telegraph/
