Firmware update 4.9.1 empowers CTEK’s CHARGESTORM CONNECTED 3 (CC3) to support Autocharge, the streamlined charging experience for drivers who will simply plug into a CC3 which automatically communicates with the vehicle and, if a payment method has been previously set up, begins charging.
The faster to use Autocharge is particularly beneficial for businesses with fleet or other workplace charging and destination charging. Its benefits also apply to public charging networks and residential community car parks. Only registered vehicles are authorised to charge, preventing unauthorised access.
Autocharge requires the driver to pre-register their vehicle with the charging network’s backend or, for the first charge only, use an RFID card or authenticate via an app. Autocharge relies on the Open Charge Point Protocol (OCPP) 1.6 and later, with CC3 supporting the latest version 2.0.1.
CTEK’s firmware version 4.9.1 also enables wireless configuration over WiFi, giving installers the opportunity to configure and commission newly installed CC3s from inside their work van, now by using a mobile phone or tablet. It also adds customisable current limits per outlet, allowing greater flexibility in distributing available power.
The new firmware also introduces key innovations for both CTEK’s current CC3 model and its predecessor, the CC2. Both models can now get wireless load balancing thanks to CTEK’s NANOGRID AIR add-on, which enables dynamic power management without physical wiring.
NANOGRID AIR reads information from a smart energy meter and communicates with a CC3 or CC2 via a local area network’s WiFi. When multiple EV charge points are in use, the CC3 or CC2 connected to NANOGRID AIR dynamically adjusts the charging current for all chargers in the installation to ensure the total load remains within the building’s available power limits.
If overall consumption increases due to other electrical demands, the system reduces charging power temporarily. Once demand decreases, more power is reallocated to the chargers. The wireless communication simplifies installation and its lack of cabling reduces costs.
It is also scalable and futureproofed, easily expanding as more charge points are added to charge more EVs. For larger sites, NANOGRID LOCAL PLUS will handle load balancing for even more charge points.
Daniel Forsberg, CTEK’s Marketing Manager EVSE, said: "This firmware update unlocks exciting innovations for EV drivers, installers, charge point operators, employers and many others.
“Autocharge will simplify the driver experience of charging and streamline administration for operators. Wireless load balancing helps limit installation costs and prevents overloading of local power limits.”
For CC3 and CC2 charge points with internet connection, firmware 4.9.1 can be deployed via ctek.com/support/software-firmware or via a charging installation’s backend provider.
