Technology bottlenecks have put a hold on the development of electric vehicles:
- Short lifespan and high cost
Currently, most domestic lithium battery makers only provide one-year warranty. Even the lithium battery of an average electric car costs about $10,000 to $13,000 thousand, which means it will incur a huge expense on the car owner if the battery needs to be changed one or two years after the purchase.
- Bad compatibility
In addition to the troublesome issue of inability to fast charge, issues such as the battery capacity plummet under low temperature and thermal dissipation demand, which consumes battery energy, under high temperature are equally knotty. Moreover, the battery performance will deteriorate as time slips, which will result in a continuous decrease in electric car performance regarding speed, acceleration and travel distance on one charge.
- Charging inconvenience
For those who live in the city without a garage, it would be difficult for them to charge at home. Even though it is possible to use a household 220-Volt outlet to charge electric cars, it also raises safety concerns. The ultimate solution to this problem is a nation-wide establishment of EV charging stations at communities and parking lots. However, it will take a long time for the EV charging network to reach the kind of popularization.
