Downhill reverse charging 125 kWh? How to achieve industry-leading energy recovery of Sany electric heavy trucks!

Downhill does not consume power, and it can also be recharged in reverse! According to the feedback from users of Sany electric heavy truck, the vehicle is driving in the downhill section with an altitude difference of 800 meters, and there is almost no power consumption, but it also charges the battery pack with 125 degrees, which increases the cruising range of the car and realizes energy recovery!

Today, we reveal two self-developed and industry-leading energy recovery technologies of Jiangshan flat-top electric heavy trucks: decoupling braking energy recovery system and multi-gear coasting energy recovery system.

When the driver presses the brake pedal, the electrical signal will be transmitted to the brake system control unit, and after the controller calculates, the vehicle can accurately distribute the electric braking and mechanical braking force.

The decoupling braking system of Sany electric heavy truck uses the motor as the main braking force provider, and the basic braking brake is only used as the brake compensation, and the two work together. While providing sufficient braking guarantee for the whole vehicle, it further achieves higher energy recovery efficiency and makes the battery life longer!

Sany self-developed multi-gear coasting energy recovery system: when the vehicle is in the driving state, after the driver releases the accelerator pedal, the drive motor changes from providing driving torque to feeding back braking torque, which will produce braking deceleration on the whole vehicle, and this deceleration process is coasting energy recovery.

Jiangshan flat-top electric heavy truck is equipped with 5-level adjustable electric retarding braking function, which makes the energy recovery rate of the whole vehicle exceed 36%.

In addition to being equipped with an efficient energy recovery system, Sany electric heavy trucks have separately developed a 9-level cruise slowing function for the long downhill road conditions often faced by mountain transportation, and the driver can achieve continuous and stable constant speed downhill through the shortcut button on the steering wheel after setting the target speed, so as to achieve more efficient energy recovery.

This process minimizes wear and heat generation in the mechanical brake system, effectively mitigating the risk of thermal decay of the brake drum. Both the stability of the braking system and the transportation efficiency have been improved simultaneously, which is definitely a "money-saving" artifact for users with long downhill operation scenarios.

The driver of Sany electric heavy truck often laughs and says, "When encountering a long downhill slope, Sany's energy recovery is to save money for the team owner, and even earn back the electricity bill!" ”

In addition, the energy recovery system of Sany electric heavy truck is a kind of flexible retarding braking, which will not only not cause a strong impact on the frame and braking system during the deceleration process, but also help to reduce the maintenance cost of the braking system and wheels.

Sany electric heavy truck's braking and coasting energy recovery system based on axle load recognition can achieve an energy recovery efficiency of more than 36%, which makes the vehicle mileage increase linearly. Low power consumption, long battery life, high operation efficiency, and real reduction of operating costs for users!
