The invention relates to the technical field of energy conservation of new energy dump trucks, and discloses an energy-saving feedback type technology applied to a battery box of an electric wheel dump truck, which comprises the following steps of: cancelling a brake resistance box of an original truck, and installing a battery pack and a charge-discharge control device at the position of the brake resistance box; the method specifically comprises the steps of electrical interface fusion research, mining dump truck energy feedback technology research, mining dump truck mild hybrid power energy-saving technology research and mechanical interface and stress analysis. According to the energy-saving feedback type technology applied to the battery box of the electric wheel dump truck, a battery pack system is used for replacing an original truck resistance box, an electrical interface and a mechanical interface are kept unchanged, the original truck is slightly changed, and recovery of braking energy and a hybrid power technology can be achieved without charging a battery pack; compared with pure electric or plug-in hybrid power transformation, the scheme is lower in cost, higher in safety, obvious in effect and good in economic benefit.
