AGVs – Shuttles
Mobile applications that run with batteries have traditionally rely on a non-standard low voltage power train, normally 24 or 48 Vdc. Although low-voltage batteries are and will continue being common, the drives and motors most used in the industrial market are AC. Learn how to improve your machines with a DC/DC converter and AC industrial elements.
DC/DC converters can be used to feed standard 230/400 Vac drives (VFD) directly in the DC bus. The energy can flow from batteries to drive and vice versa due to the bidirectionality and embedded control in the converters. This solution at industrial voltages is especially interesting when the power consumption of the vehicle surpasses 2kW as the operation at low voltage implies dealing with high currents that increase weight, dimensions and cost of cables, motors, and controllers.
Complete and easy integration
epic power bidirectional DC/DC converters automatically detect consumption and generation so the vehicle can return excess energy back to the batteries. A simple connection to the DC link of any AC drive allows for a high flexibility and simplicity in mains and non-mains connected vehicles.
Additional battery charging capabilities
The bidirectional connection to the DC link of a drive enables the operation of the DC/DC converter as a battery/supercapacitor charger when connected to the mains. Battery charging profile can be chosen to ensure any chemistry and capacity are treated accordingly.
Connectivity
Thanks to the multiple power and peripheral connections which our DC/DC converters have and because the CAN communication is possible to obtain valuable information about the state of the converter, voltages, currents and consumptions of every single system (drive, brakes, controller…) to optimize the usage and the charge of the battery
Case studies
AGVs & shuttles (supercapacitor powered)
Bidirectional DC/DC converters applied to shuttles allow energy consumption from supercapacitors and charge from the grid with only one component. Electrified monorails become unnecessary in warehouses.
