Electric cylinders achieve a 23% energy efficiency improvement in new energy vehicle production lines
through the following technical approaches:
1. High-Precision Control in Battery Module Assembly
Micro-servo electric cylinders achieve a revolutionary breakthrough in battery module pitch adjustment:
By integrating micro-electric cylinders within the narrow slider spacing of just over ten millimeters, they
replace traditional manual micrometer adjustment and enable real-time, synchronous control of 120
adjustment sliders. This technology addresses the pain points of low manual operation efficiency and
large errors, significantly improving battery quality and production capacity, and becoming a core
component of energy efficiency improvement.
2. Energy Recovery Optimization in Testing
In charging pile production line testing, a multi-channel parallel testing system is employed, combined
with intelligent temperature-controlled air cooling technology driven by electric cylinders:
95% energy regenerative rate: Electricity generated during the testing process is fed back into the grid
via inverter technology;
50% reduction in single-pile testing time: Multi-channel parallel testing reduces work hours and unit
energy costs;
Intelligent Temperature Control System: The air cooling device driven by the electric cylinders precisely
controls the test environment temperature, reducing ineffective heat dissipation. III. Electronic Control
System Integration and Energy Reuse
Inverter Brick Technology Support: The electric cylinder-driven assembly line is compatible with 800V
SiC inverter brick modules, which significantly reduce system internal resistance losses by increasing
power density.
Common DC Bus Technology: When multiple motors operate in coordination, braking energy is transfer
red to other electric cylinders via the bus in real time for reuse, reducing energy waste.
Modular Architecture: Standardized electric cylinder modules are quickly compatible with 400V/800V
platforms, eliminating the additional energy consumption associated with production line reconfigura
tion.
The electric cylinders replace hydraulic/pneumatic systems with precision mechanical transmission,
eliminating fluid medium energy loss. Combined with the high efficiency of servo motor direct drive
(efficiency exceeding 99.5%), this ultimately improves the overall energy efficiency of the production
line by 23%.
