China-made on-board charger (OBC) is priced at RMB1,000-4,500/unit for the moment. The larger power it is, the higher price will be. OBC falls into three types by power: <2.5KW, 3-5KW (mostly 3.3KW), and >6KW, respectively for EVs with battery capacity less than 15kWh, 15-24kWh electric passenger cars and small logistics vehicles, and 24kWh-above electric commercial vehicles and logistics vehicles. Market price of 6.6KW charger stands at RMB3,500-4,500, 3.3KW at RMB1,500-2,000 and 2KW at around RMB1,000. Large power OBC is growing a trend as individual users and ride-hailing firms require far shorter charging time. 6.6KW OBC will win popularity; 10KW-23KW large power ones will find wider application. By RMB3,500 per unit, the OBC market size will be RMB7 billion in 2020; the DC/DC market will be valued at a staggering RMB3 billion in 2020 as long as the price of DC/DC converter is kept at RMB1,500.
