Disclosed is a new energy commercial vehicle energy efficient recovery system. The new energy commercial vehicle energy efficient recovery system is characterized in that an electric generator is connected with a storage battery, the electric generator is connected with an ECU (electronic control unit) through an electric generator controller, an acceleration sensor and a displacement sensor are arranged on an electromagnet foot valve, the displacement sensor is used to measure the descending position of an ejection rod, the acceleration sensor moves along with the ejection rod, the acceleration sensor is used to measure the descending accelerated speed of a pedal, the acceleration sensor, the displacement sensor, the storage battery and a proportion relay valve are respectively connected with the ECU, a brake pedal work angle of the maximum point braking of the electromagnet foot valve ranges from 11 degrees to 12.5 degrees, and a brake pedal work angle of the maximum semi-braking of the electromagnet foot valve ranges from 19 degrees to 20.5 degrees. The new energy commercial vehicle energy efficient recovery system is obtained by optimizing a new energy commercial vehicle energy efficient recovery system in the prior art, and the optimized new energy commercial vehicle energy efficient recovery system can recover 50% of energy at most when a vehicle brakes, greatly improves charging efficiency, and reduces wear of friction braking on a brake and related components.
