Overview
Description
This modular electric vehicle supply equipment (EVSE) system simplifies development and accelerates deployment of smart electric vehicle (EV) chargers. Our controller board stacks over a power board and supports flexible 1-phase to 3-phase charging up to 22kW. We integrate Wi-Fi, Bluetooth® Low Energy (LE), NFC, and optional Ethernet to meet diverse connectivity needs. By using high-voltage AC/DC, we eliminate optocouplers and reduce system complexity. Our dual-bank flash MCU enables secure OTA updates with rollback, helping developers maintain reliability while scaling efficiently.
Features
- Supports flexible configurations for 1-phase to 3-phase charging systems for power up to 22kW.
- MCU supports dual-flash bank operation, allowing safe over-the-air (OTA) updates and fallback.
- High-voltage AC/DC eliminates the need for optocouplers, simplifying the system architecture.
