<p>Through the £246m Faraday Battery Challenge (FBC), the Government is investing
in research and innovation projects and new facilities to scale up and advance the
production, use and recycling of batteries. Projects funded so far include ones to
improve battery lifespan and range, and increase the reuse, remanufacture and recycling
of batteries at the end of their lives.</p><p> </p><p>The life of electric vehicle
batteries generally depends on numerous factors, which makes it difficult to be precise
about average battery life. Car manufacturers are well aware that potential customers
are concerned about battery longevity, and many of them offer warranties tailored
to the needs of electric vehicle motorists.</p><p> </p><p>A requirement for the Government’s
Plug-in Car and Van Grant schemes is that eligible vehicles must have: either a minimum
5-year warranty on the vehicle’s battery and electric drive train as standard; or
extra evidence of battery performance to show reasonable performance after three years
of use. More generally, battery warranties are getting longer (in mileage and years)
as battery technology improves and the industry grows more confident about battery
degradation.</p><p> </p><p>The Government has made no assessment of the effect on
the battery life of electric cars of charging too frequently, infrequently or using
different charge points. However, some vehicle manufacturers are developing ambitious
targets for their primary battery life.</p><p> </p><p>The Government’s Road to Zero
strategy showed that battery electric vehicles have substantially lower greenhouse
gas emissions than conventional vehicles, even when taking into account the electricity
source and electricity used for battery production. Between now and 2050 it projects
that grid emissions will fall by around 90% with total emissions from electric vehicles
falling in parallel.</p><p> </p>
