| It decouples innovations between car and battery technology. Car manufacturers will only innovate batteries to the extent that fits their pricing and performance models. With the decoupling, the market for batteries will expand and different types of batteries for different performance / technologies will come into picture. But by making it legal to sell cars without batteries, it obliges car manufacturers to come up with data, certifications, technology transfer systems, etc to legally allow battery manufacturers to support their cars. This reduces a lot of paperwork and other red tape. For example, insurance. If you buy a car and change it's battery, your insurance provider may object for coverage or charge you extra for after market modifications. So, while the user has to buy the battery, he will have more choice. Also, new battery technology and new battery companies can grow with more ease. There are some downsides to this approach. Many vehicle dynamics and safety tests are conducted for the vehicle as a whole. So it has to be seen how those issues are addressed. However, since the location of the battery, in a given vehicle is fixed, I think coming up with a framework of certifications or standardized parameters for battery physicals should be easy. I think this law is primarily aimed at taxis and auto-rickshaws in many urban areas. Most of India's middle class still drives bikes and scooters. However, there are many taxis and autos. And these are usually very polluting. Shifting to an EV is usually more cost effective for the driver. The cost per kilometer of travel is lesser in EVs. |
