More compact, efficient AGV solutions with bi-directional DC/DC converters
Battery-powered Automated Guided Vehicles (AGVs) traditionally use low-voltage DC motors. Because the battery voltage is low, a high current must be supplied to achieve the same power output. This requires larger, heavier, and more expensive motors.
| Low voltage side [V] | High voltage side [V] | Power [W] |
|---|---|---|
| 32–57 VDC | 600–630 VDC | 11.000 |
By placing a DC/DC converter between the battery and the drive, a bulky low-voltage motor is no longer necessary. The converter boosts the battery voltage and thus powers a standard 230 or 400 VAC frequency inverter. This creates a more compact, lightweight, and cost-efficient drive solution.
Additional benefits
- better speed control and synchronization
- lower price, weight and dimensions
- proven current technology, no complex control
- braking energy back into the battery
- no external battery charger required
- insight into the state of charge (SoC)
- faster loading times, so less downtime
EPIC Power's bi-directional DC/DC converters enable the use of standard variable speed drives (three-phase or single-phase) and synchronous motors on existing battery systems.
Using AC motors instead of DC motors not only provides better control, acceleration and torque, but also higher efficiency and lower costs for the complete AGV solution.
