The real problem with electric cars is the battery, which when it breaks down, is a major cost to repair, needing specialist work. It is no longer the case of taking one’s car to the mechanic down the road to get him to fix things up in the morning for a pickup later in the day. Jonathan Hewett, Chief Executive of Thatcham Research, the motor insurers’ automotive research centre, has said “The challenge is that we have no way of understanding whether the battery has been compromised or damaged in any way.
“The threat of thermal runaway means that a catastrophic fire can take place if the cells of the battery have been damaged in a collision. “What we’re struggling to understand at the moment is how we approach that diagnostic technique. “It’s like a doctor trying to understand what’s wrong with you without any notes or an X-ray.”
