The establishment of comprehensive and application-specific DC charging infrastructure requires diverse charging solutions.Phoenix Contact
With a comprehensive and reliable DC charging infrastructure, charging electric cars on medium and long-distance journeys at semi-public and public electric charging stations is more than suitable for everyday use. Long charging times are a thing of the past.
Even with uncooled DC charging cables, charging currents of up to 375 A and correspondingly short charging times can be achieved. The power transmission requirements vary greatly, however, depending on the installation location and the application. For many operators, it therefore makes sense to provide charging infrastructure that is optimised to the application.
The robust Charx connect DC charging cables from Phoenix Contact have future-proof and sustainable features, as well as a wide range of power versions from 150 A to 375 A.
The right power in the right place
Charging infrastructure should always be selected and established in accordance with application-specific criteria. In this context, it makes no sense to set up a DC home charger in a motorway parking lot or an HPC quick charging station in a residential area with single-family homes. The relevant criterion is the average time a vehicle spends at the corresponding location: HPCs are the best solution if as much range as possible is to be recharged in a short time, for example, at motorway rest stops, on charging parks near motorways, and on interstates.

Using charging stations in the medium power range of around 50 to 100 kW makes the most sense when the dwell time is between 30 minutes and 2 hours. This applies, for example, to parking lots outside shopping centres, hardware stores, supermarkets, furniture stores, and other businesses.
Simple DC charging with lower charging powers makes sense wherever the dwell time exceeds several hours. This is particularly true for tourist destinations, such as amusement parks, sports stadiums, and other venues.

DC charging can also make sense in private and professional applications, especially if DC voltage can be provided easily (e.g., via a large photovoltaic system). However, it is not simple to differentiate this from AC charging without further consideration; the application must also be examined carefully here. The charging cables from the Phoenix Contact portfolio cover a wide range of DC charging applications. This enables cost-effective and demand-based DC charging infrastructure to be installed in the field.
As a part of the portfolio, the new generation of the proven CHARX connect standard CCS charging connectors covers the medium power range from 150 to 250 kW. In the same housing design, Charx connect professional does not use liquid cooling and instead uses a conductor cross-section of 4 x 50 mm². This means that HPC charging stations can be operated at 375 A continuously and safely without cooling at up to 40°C and with even higher charging currents for short periods in Boost Mode.
The clever sealing concept of the Charx connect standard DC charging cables ensures complete longitudinal water tightness, which completely protects the live parts inside the housing against moisture. This maximises electrical safety for the user while increasing the failsafe performance of the charging infrastructure.
The innovative two-chamber sealing system marks the next stage in the development of the DC charging cable sealing systems from Phoenix Contact: by physically separating the DC+ and DC- power contacts, short circuits can be completely ruled out.
High-quality materials also ensure the necessary robustness and long service life of the charging connectors - even in constant outdoor use under harsh conditions.
Prepared for four-conductor measurement technology
For the reliable billing of charging processes compliant with calibration laws, the DC charging cables and connectors are already prepared for four-conductor measurement technology and are thus future-proof.
The four-conductor measurement technology allows recording of the power dissipation in the charging cable in order to precisely determine the energy transferred to the electric vehicle.

Sustainable, easy, and cost-effective: repair kits
Despite being made of robust materials, charging connectors at semi-public or public charging stations require regular maintenance, also as a result of improper handling. The damage usually occurs on the mating face. With the help of repair kits, mating face frames and power contacts on the charging connector can be replaced quickly and easily.
Repair kits support simple, cost-effective, and above all, sustainable maintenance of the charging infrastructure.Phoenix Contact
This makes the Charx connect DC charging cables particularly easy to maintain, saves time and costs, and increases the availability of charging infrastructure in the field. This eliminates the need for time-consuming and costly replacement of the complete charging cable. This type of maintenance is not only more economical, but also more sustainable.
Summary
The new generation of the proven and uncooled Charx connect DC charging connector covers the medium to increased power range from 150 to 375 kW and thus supports the demand-oriented extension of DC charging infrastructure. In the new housing design, the product family offers many improvements in terms of robustness, safety, billing, and maintenance.
E-mobility in an All Electric Society
The All Electric Society is a future in which electrical energy generated from renewable sources is available worldwide as the primary type of energy in sufficient quantities and that it is affordable.
A key to achieving this vision of the future is the transformation of the mobility sector over to e-mobility. Phoenix Contact provides a broad charging technology portfolio for both the vehicle charging interface and for the charging infrastructure. At Phoenix Contact, all charging technology components for e-mobility are bundled under the Charx brand. This creates networked, complete solutions for environmentally friendly, sustainable mobility.
