EV Charging · Standard boards
Proven controller boards for EV chargers
The standard boards are the hardware building blocks of the charging module range. Take a single controller or the whole set - a proven foundation you can design your charger around, rather than developing and certifying the electronics from scratch.
The range
Communications, AC power and everything around them
MantaRay handles the communications, EEL handles the AC power, CongaEEL combines EEL with power path components, and the peripherals finish the product. Each board does one job well, so your design stays simple.
Communications + power
CongaEEL integrated charge controller
Communications and AC power control on a single board - the integrated option for simpler, single-socket chargers where a two-board split is more than you need.
Communications · cost optimised
MinnoRay compact AC charge controller
Ethernet, LTE Cat 1 bis, Wi-Fi and Bluetooth on one compact board, without the overhead of a full Linux controller. Stacks with CongaEEL for single or dual socket three phase chargers.
AC power control
AC charge controller (EEL)
A compact, cost-effective AC charge point controller compliant with IEC 61851. Runs under MantaRay so one controller can drive several EEL boards for multi-socket charging.
Communications
Smart charge point controller (MantaRay)
The OCPP communications controller - the brains of a connected charger. Handles connectivity, authentication, metering, load balancing and protocol compliance across AC and DC.
Accessories
Charger peripherals
RFID readers, displays and LED boards that complete a charger and speed up integration - designed to sit alongside the MantaRay and EEL controllers.
Why start from a board
A faster, lower-risk route to a charger
Off-the-shelf chargers are too rigid; full custom development is slow and risky. The standard boards give you a compliant, manufacturable foundation you can configure around your product - keeping your brand, your IP and your roadmap.
How we design a bespoke chargerStandards built in
IEC 61851, OCPP and ISO 15118 compliance designed in from the start, not retrofitted at certification.
Mix and match
Take one board or the whole set - the boards slot into your existing enclosure and design.
Built for volume
Compact layouts and a minimal bill of materials keep unit cost and assembly effort down at scale.
