Hybrid Propulsion Systems (PHEVs)

How the DM-i Hybrid System Works

The BYD Song Plus DM-i uses Plug-in Hybrid (PHEV) technology, which allows you to charge the battery from an external source of electricity. This system consists of two main components: an electric motor and an internal combustion engine
