BYD has been working to resolve challenges in developing new energy vehicles, including the high cost of battery packs and the limited range of electric vehicles on the market. As a solution, BYD came up with an exclusive Dual Mode(DM) electric vehicle technology that allows users to manually switch to an all-electric mode or switch to an hybrid-electric mode engaging an internal combustion engine. The DM electric vehicles can charge themselves independently with easy connection to a normal household socket and thus never use the ICE engine until a user wishes.
The BYD DM electric Vehicle system is the next generation of the current hybrid system, and might be the most advanced one in the world. The BYD DM electric vehicle incorporates an advanced generator and motor controlling technology with a 1.0 liter gasoline engine as a range-extender. This provides both robust performance and good fuel economy with low emissions. It uses multiple energy supplies and good fuel economy with low emissions. It uses multiple energy supplies via both grid recharging and gasoline refueling, which is why it is called a dual mode hybrid system.
