BYD ECB25 Forklift Technical Details: Dual AC Drive System and Energy Recovery Function Description

In various operating scenarios such as warehouse handling and short-distance material transfer in the factory, the power performance and battery life of electric forklifts have always been the core indicators that users pay attention to. This time, the two core technical details of ECB25 electric forklifts are clearly explained.

Dual AC drive system core technical details

Dual drive structure design logic

This dual AC drive system is equipped with independent AC drive motors for the left and right drive wheels of the vehicle, abandoning the traditional design idea of a single motor linking the wheels at both ends through the differential. The whole set of power link has no carbon brush components, and does not require regular carbon brush replacement and maintenance. This reduces the operation and maintenance cost of long-term use from the structural level. The circuit layout is fully sealed and protected, which can be adapted to the working environment with a lot of dust and a small amount of water splashing.

Daily operation advantages

The two independent drive motors can automatically assign different power outputs according to the real-time steering angle and driving speed of the vehicle. When the vehicle is steering in place and turning around in a narrow channel, there is no need for additional power assist devices. The steering process is smooth and card-free. When climbing heavy loads, the two wheels can output stable torque synchronously to avoid the situation of single wheel skidding and idling. The whole process power response follows the foot, and the operation difficulty is lower. Novice drivers can also quickly adapt.

Practical application description of energy recovery function

Functional work running logic

This energy recovery function can convert the inertial kinetic energy generated by the vehicle into electrical energy and recharge it into the power battery pack during the process of the vehicle releasing the accelerator and sliding and depressing the brake pedal. The system can automatically adjust the recovery force according to the depth of the brake pedal, so as not to cause the vehicle to stall due to excessive recovery force, and it will not affect the driver's normal operating habits.

scene adaptation use value

In a high-frequency start-stop storage operation scenario, this energy recovery function can effectively extend the continuous operation time under a single set of full power, reduce the user's charging waiting frequency, and reduce the overall power consumption for a long time. At the same time, it can also reduce the wear degree of the brake pads, further lengthen the replacement cycle of the brake components, and reduce the cost of use throughout the life cycle.
