High cost of batteries has always been a deterrent in the success of electric cars. However, with China investing heavily in electric vehicles, the cost of batteries has begun falling. China is also battling with record-high pollution in its cities, leading to a mass interest in electric cars. “We have worked across, for our passenger and commercial vehicles, on hybrid technologies and battery electric technologies. The barrier to electric technology is the high cost of batteries. Battery costs have started to come down. The rate of reduction cost is accelerating. We have always seen hybrids as a path towards this type of technology and we will see this getting integrated into our future vehicles,” said Timothy Leverton, president and head, advanced product engineering, Tata Motors.
