The Rolec UltraCharge 40 DC EV Charger is a grey 40kW rapid charger with one 5m CCS2 cable and cable management system. ROLEC04040 is the single-output UltraCharge 40 variant, rated at 40kW DC with 1 x CCS2 connection and a 5m 150A rated charging cable. It is designed for businesses that need faster turnaround than AC charging can provide, without specifying a larger 80kW or ultra-rapid charger. The charger uses Mode 4 DC charging, accepts a 400V AC three-phase input and supports a 150V to 1000V DC output voltage range. Operation can be handled through plug and go, mobile app or RFID, with optional contactless payment hardware available separately. A 10.1-inch LCD display and cable management system are included, supporting driver use at customer and fleet sites. OCPP 1.6J, 4G, Wi-Fi and Ethernet communications allow integration with compatible chargepoint management systems. Browse commercial EV chargers for wider AC and DC project options.

Where a 40kW DC charger fits

A 40kW DC charger is specified when AC charging is too slow for the site’s dwell time, but the project does not need an 80kW or higher charging station. It suits fleet yards, workshops, workplaces, dealerships, marinas and customer sites where vehicles need a meaningful top-up during the day. The charger can deliver up to 40kW through CCS2, adding faster DC charging capability without the electrical demand of larger rapid units.

The 40kW level is a practical step between AC destination charging and higher-power rapid charging. It can serve vehicles that stop for longer than a motorway-style rapid session but shorter than a full working day. Site operators should still assess vehicle battery capability, expected dwell time and grid capacity. The charger’s output can be configured to lower levels where the supply is constrained, so it can be designed around real site limits rather than assuming full output on every installation.

CCS2 cable and cable management

This SKU provides one CCS2 DC charging output with a 5m cable. The cable is rated at 150A and is listed as capable of delivering the 40kW charge rate to a standard 400V vehicle. CCS2 is the relevant connector for many current DC-capable electric vehicles, making the unit suitable for mixed customer or fleet use where vehicles share one rapid bay.

The cable management system is supplied as standard, which matters on DC equipment because the cable is heavier than a typical AC charging lead. Good cable management helps reduce user handling issues and keeps the charging bay tidier between sessions. An optional 7m cable is available in the range for sites where the charger must sit further from the vehicle inlet. The 5m cable on this SKU should be checked against the bay layout before the mounting position is finalised.

OCPP control and user operation

UltraCharge 40 can be operated through plug and go, mobile app or RFID access. These routes cover private fleet use, staff charging and managed public or semi-public charging, depending on the chosen chargepoint management system. An optional NFC or contactless card payment terminal is available where the site needs direct payment at the charger.

OCPP 1.6J communications give the charger a route into compatible management platforms. OCPP 2.0.1 is listed as future support. The communications package includes 4G GSM with built-in nano SIM, Wi-Fi and RJ45 Ethernet. That gives designers more than one way to keep the charger connected on sites where mobile signal, network infrastructure or cabinet location may vary. Management features remain subject to the CPMS selected for the project.

Protection and three-phase supply checks

The charger includes a 30mA Type A RCD, undervoltage and overvoltage protection, DC overcurrent protection, over temperature protection, a surge protection device, an emergency stop button, flood and smoke detection, and relay welding detection. Static and dynamic load management are software configurable, although additional hardware may be required. These features help the charger operate within the site’s electrical capacity and reduce the risk of overload.

The electrical input is 400V AC, plus or minus 10%, with a 3P + N + PE input type. The data sheet lists 63A input current and 44kVA input power for ROLEC04040. Designers should consider transformer capacity, distribution board space, protective device selection and cable route before committing to the charger location. Supporting site devices can be planned through EV circuit protection, with the DC charger’s manufacturer instructions taking priority.

Cabinet, display and mounting choices

The cabinet measures 550mm wide, 1150mm high and 255mm deep. Including pedestal, dimensions are listed as 550mm wide, 1700mm high and 300mm deep. The unit body is stainless steel with an all-weather powder-coated finish, and the product colour is grey. The enclosure is IP54 rated, IK10 enclosure protection is specified, and the screen protection rating is IK08. Operating temperature is listed from -30°C to +50°C.

The 10.1-inch LCD display provides the local user interface, supported by an RGB LED status indicator and RFID reader. The mounting pedestal and ground mounting base are listed as options, so the installed format should be chosen around wall position, bay layout and foundations. Where the charger sits close to vehicle movement, a root mount EV chargepoint protection barrier or surface-mounted barrier can help protect the equipment.

Choosing between UltraCharge 40 variants

ROLEC04040 is the 40kW UltraCharge 40 with one 5m CCS2 output and CMS. ROLEC040240 is the related 40kW model with two 5m CCS2 outputs and CMS. The single-output model suits one rapid bay and gives the full station output to one vehicle. The dual-output model is selected where the operator wants to connect two vehicles, with power allocation and user experience planned around shared use.

UltraCharge 80 increases the station level to 80kW and provides two CCS2 outputs as the standard listed format. UltraCharge 180 and UltraCharge 400 serve higher-power sites where grid capacity, traffic volume and return on investment justify a larger rapid or ultra-rapid installation. Choose the 40kW single-output model where one compact DC bay is enough and where the site wants a controlled step up from AC charging.
