EV charger module TH15DD7560C7-WT

DC

Product brief
TH15DD7560C7-WT, the bidirectional DC-DC charging and discharging module from Tonhe, is designed for high-power EV charging stations based on a DC bus and for micro-grid energy storage systems with PCS. The module uses a Dual Active Full Bridge (DAB) extension topology to enable bidirectional energy flow, high-frequency galvanic isolation between input and output, a wide voltage range and compact power density.

Product introduction
The TH15DD7560C7-WT supports bidirectional charging and discharging with isolated high-frequency coupling between input and output. It is intended for integration into EV charger cabinets and microgrid storage racks where space, isolation and bidirectional control are required. The unit features fan cooling and a digital interface for address setting and configuration.

Main characteristics

• Topology: Dual Active Full Bridge (DAB) extension structure
• Bidirectional energy flow: supports forward (high→low) and reverse (low→high) power transfer
• High-frequency electrical isolation between input and output
• High power density with fan cooling
• Digital screen display and button operation for address/setting
• Communication: CAN protocol (module default baud rate 125 kbps)

Additional product information
Manufacturing and quality processes include automated SMT production lines, solder paste printing and inspection, wave soldering, conformal/coating lines, aging test lines and full quality assurance procedures. Certifications on record include ISO9001 and IATF16949; modules and chargers carry CE, TUV and other certifications. Standard warranty: 12 months from receipt of shipment.
