An EV charger’s screen is the part drivers touch, and it is also the part that fails first when it is badly specified. Outdoor chargers face direct sun, rain, dust, extreme temperatures and vandalism, while the controller behind the screen has to talk to meters, power modules, RFID readers, payment terminals and an OCPP back-end. TouchVision supplies EV charger touch screens, HMI modules and controller boards from its own factory, and customizes them for AC wallboxes and DC fast chargers.
What we supply for chargers
- Touch displays, 7″ to 15.6″ and larger: infrared or projected-capacitive touch, toughened anti-glare glass, high-brightness options for sunlit sites and IP65 front sealing.
- Controller boards: the TV-RK3568 for rich Android/Linux UIs with 4G/Wi-Fi, five RS-485 ports and CAN; the fanless TV-AM3354 and compact AM3354 2-in-1 board for cost-optimized AC chargers.
- Complete HMI modules: display + touch + board + cabling delivered as one tested assembly, ready to bolt into your enclosure.
- Site monitoring: the TV-IS013 gateway for meter and inverter data, and AI video boxes that detect smoke and fire in charging sheds.
Customization options
Screen size and aspect ratio, brightness, glass thickness and coating, bezel and cable exit, connector positions, RS-485/CAN/Ethernet count, 4G/Wi-Fi/Bluetooth modules, power input (12V or 24V), operating temperature, and a preloaded OS image with your UI. We can match the mechanical outline of an existing part to make TouchVision a drop-in second source.

Frequently asked questions
What touch screen is best for an outdoor EV charger?
A sunlight-readable display with toughened anti-glare glass and an IP65 front. Infrared touch works best with gloves and rain; PCAP gives a smartphone-like feel under a canopy. TouchVision supplies both.
Which controller board does TouchVision recommend for EV chargers?
The TV-RK3568 for DC chargers or premium AC chargers with rich UIs and 4G, and the low-power TV-AM3354 or AM3354 2-in-1 for cost-optimized AC chargers.
Can TouchVision match the size of my current charger display?
Yes. TouchVision can match the outline, mounting holes and connector positions of your existing display or board so it can serve as a drop-in second source.
What is the minimum order quantity?
TouchVision supports small-batch pilot orders for new charger models. Send your expected annual volume in the RFQ form for a quotation.
