A Closed Loop, Driven Daily... A Pure Electric Heavy Truck That Doesn't Need Charging

@郭弋搏-小郭同学：I roughly understand this statement

BYD's pure electric heavy truck
loads up with mineral sand at the top of the mountain and unloads at the bottom
Going downhill with a full load, the truck is heavy, so the regenerative braking is strong, charging the battery while driving.

After unloading at the bottom, the empty truck is lighter
The electricity needed for the empty truck to return to the top
is less than the electricity charged through regenerative braking while going downhill with a full load...

The gravitational potential energy of the mineral sand offsets the mechanical energy of the vehicle's movement
It forms a closed loop, driven daily... no need to charge ​​​

@冯潇:It seems feasible. Simply put, the dozens of tons of minerals moving from high to low have enormous gravitational potential energy. The electricity generated through the electric truck's regenerative braking exactly covers the electricity needed for the uphill climb. If that doesn't work, understanding the electric truck as an elevator that can recover electricity makes it easier to comprehend; it can also be understood as a form of power station
