Downhill does not consume electricity，It can also charge in the reverse direction.！SANY Electric Heavy Truck User Feedback，The vehicle is traveling in a downhill section with an altitude drop of 800 meters.，Almost no power consumption，Instead, return the battery packCharged with 125 degrees of electricity.，The range of the vehicle is increased.，Achieve energy recovery！

Today, two independent research and development projects of Jiangshan flat-top electric heavy truck are revealed.、Industry-leading energy recovery technology：Decoupling braking energy recovery system and multi-gear sliding energy recovery system。

Decoupling braking energy recovery system independently developed by SANY：The decoupling of mechanical braking and electric braking can be realized.，When the driver depresses the brake pedal，The electrical signal is transmitted to the brake system control unit，After calculation by the controller，The whole vehicle can accurately distribute the electric braking and mechanical braking force.。

The decoupling braking system of SANY electric heavy truck takes the motor as the main braking force provider.，Basic brake braking is only used as brake compensation.，The two work together。While providing sufficient braking guarantee for the whole vehicle,，Further realizationHigher energy recovery efficiency，Makes it last longer.！

Multi-gear sliding energy recovery system independently developed by SANY：When the vehicle is running，When the driver releases the accelerator pedal，The driving motor changes from providing the driving torque to feeding back the braking torque，Braking deceleration will be generated on the whole vehicle.，This deceleration process is the coasting energy recovery.。

Equipping of Jiangshan flat-top electric heavy truckLevel 5Adjustable electric retarding function，So that that energy recovery rate of the whole vehicleSuper 36%Above。

Sany electric heavy truck is equipped with efficient energy recovery system.，In view of the long downhill road conditions often faced by mountain transportation,，A 9-level cruise retarding function has been developed separately.，After the driver sets the target speed through the steering wheel shortcut button，The vehicle can achieve continuous and stable constant speed downhill.，Achieve more efficient energy recovery。

This process minimizes wear and heat generation in the mechanical brake system，Effectively reduce the risk of thermal recession of the brake drum。Whether it is the stability of the brake system or the efficiency of transportation.，All get a synchronous promotion.，For users with long downhill operation scenarios，This is definitely“Save money”Artifact。

Drivers of Sany electric heavy trucks often laugh.“Encounter a long downhill，Trinity's energy recovery is to save money for the team owner.，I even earned back the electricity bill.！”

In addition，The energy recovery system of SANY electric heavy truck belongs to flexible retarding braking.，During deceleration，Except not to the frame.、The braking system causes a strong shock.，It also helpsReduce maintenance costs of braking system and wheel。

Braking and Coasting Energy Recovery System Based on Axle Load Identification for SANY Electric Heavy Truck，AchievableHigher than 36%Energy recovery efficiency，So that that endurance mileage of the whole vehicle is increase in a straight line。Power consumption is low、The battery life is long、Operational efficiency is high.，Really reduce operating costs for users！
