Distributed DC Fast Charging With Kempower Satellites

Due to the non-harmonized location of the charging socket on the vehicle side, achieving the best parking topology can be a challenge. This can be addressed with a distributed EV charging system, where each satellite post conserves parking space and optimizes cable maneuverability. With its record-breaking smallest footprint, the optimal location for each double-output satellite post is on every second crossing corner, and for each single-output satellite post, it’s in the top-left corner. However, based on a long track record of successful charging sessions, it’s safe to recommend a drive-through parking topology with single-output satellites. The ultimate target must be the user experience – Kempower Satellite posts can assist you in reaching that target.

Kempower Satellite

Kempower Satellite Posts for Distributed EV Charging

There is a wide selection of Kempower Satellite posts to meet all types of EV charging applications. The sturdy aluminum frame is made of two profiles, and it hosts an advanced spring-assisted charging cable handling system. This unique cable handling structure not only partially assists the user by carrying the heavy cable but also prevents the cable from scratching the ground. Depending on the desired charging power levels, a suitable combination of spring, cable, and plug can be selected. On CCS plugs, the peak power level can be up to 400 kW, and with CHAdeMO, it can be up to 100 kW. Each Satellite post can have single or double outputs (plugs). The latter can be more cost-efficient but may pose challenges for cable reach; therefore, it can be a more perfect fit for bus depot charging when the sockets are located under the front panel.

As mentioned earlier, the single-output Satellite posts are recommended for drive-through topology, but they also fit side-by-side topology. The single-output approach introduces less stress to the user, as the socket is most often within the comfort zone – in an easy-to-move-around area. At public charging sites, user authentication can be based locally on RFID tags, utilizing the integrated RFID reader or on payment terminals that can be attached to the sub-frame on the Satellite post’s front panel or on the user’s smartphone via CPO’s mobile application. Users can follow their charging sessions with a mobile device by scanning the session-based QR (Quick Response) code on those Satellite posts that are served through ChargEye connectivity services. Despite its slender design, push buttons, plug holders, and an optional energy metering display are furnished at the lower section of the frame to ensure easy usage for anybody, from teens to grandparents. The touch-screen display provides generic information in real-time, as well as optional deep details through pressing clear symbols.

Kempower AC Satellite

Kempower AC Satellite for Unity

To achieve a uniform appearance in the charging area, two options for AC charging are available. The AC Satellite post has either two Type 2 sockets or plugs with cables. With its identical structural design to the DC Satellite post, spring-assisted cable handling speeds up plug-in hybrid and fully electric vehicles, ensuring that the cable and plug are always ready for service. Please remember that the dimensioning of AC Satellite posts needs to be with a factor of 1, as local smart charging is currently not available. The maximum power level can be adjusted from the ChargEye, up to 22 kW on each charging point – naturally depending on supply and cabling. Additionally, upstream RCD type A is recommended, along with MCBs of 3 x 32 A on the supply.

Kempower Power Unit

Kempower Power Unit – Rectifier Cabinet

In the current product portfolio, there are three rectifier cabinets – single, double, and triple – available, each with a capacity of up to 600 kW. These cabinets convert the AC power supplied by the grid to DC for EV charging. In the distributed EV charging system, PU cabinets can be located remotely, providing power from distances of up to 50 meters apart, enabling Satellite posts to be positioned with the best flexibility in the market. Each Power Unit cabinet consists of 1 to 4 Power modules, one optional Dynamic module, and one Control module. Supply cabling from a circuit breaker or a 3 x 400 A MCB is required for each fully equipped PU cabinet. Each cabinet can power 1 to 6 or 1 to 8 charging points, depending on the desired configuration. Due to galvanic isolation on DC modules, all power channels can be re-routed during charging sessions to achieve the highest utilization level and increase user satisfaction due to shorter charging times.

Kempower Movable Charger

Kempower Movable Charger – On-Demand Charging Service

For multiple EV charging applications, the Movable Charger is the easiest way to start DC charging. It requires just a 3 x 63A industrial socket to operate. Although it is small and movable, it inherits all the functionalities that a large system may have. The three most popular variants are a single CCS, double CCS, and CCS & CHAdeMO. The rolling frame has one Power Module inside with two 20 kW channels that can be routed to a single or two outputs. The touchscreen is located at the top of the unit, providing generic information in real-time, as well as optional deep details through pressing clear symbols.

Kempower Station Charger

Kempower Station Charger – More Power in a Compact Unit

In several EV charging applications, the Station Charger can be the most cost- and space-efficient solution. The Station Charger inherits the PU cabinet as a frame, touchscreen, and 1-2 combinations of spring, cable, and plug on the side panel. One Station Charger application is bus depot charging, where the charging socket of the bus is located under the front panel. In some cases, a public EV charging service can be based on a double-output Station Charger that can be extended with two remotely located single-output Satellite posts. The most popular structure has two outputs and requires supply cabling from a circuit breaker or a 3 x 400 A MCB to a fully equipped cabinet.
