On 14 January 2014, [[CRRC Changchun Railway Vehicles]] announced that hybrid electric multiple units were put into production. At the end of 2014, the first batch of hybrid EMUs, one train each with battery-catenary power supply (EEMU) and catenary power supply-internal combustion engine (DEMU), rolled off the assembly line in Changchun. From 2016 to 2020, the vehicles were tested in Hohhot and Beijing Academy of Railway Sciences.

In September 2022, the first CJ-5 train used by the [[Xi'an]]-Huxian Railway arrived in Xi'an. The No. 0506 train, which uses an internal combustion engine and a battery hybrid, was used as a vehicle during the initial operation of the Xi'an-Huxian Railway. During the operation period, it will be temporarily managed by [[Xi'an Metro]].
