2016-01-03 - HyperCharging Station

HyperCharging is an innovative way in which Electric Vehicles (EVs) can be  charged in the future. We would also like to point out that HyperCharging is not oriented towards domestic charging, but is aimed as a direct replacement to fueling stations.

In order to understand better what HyperCharging is all about, we will explain how the whole concept came to be. When Silex started its venture in the EV market, we knew that charging was (and is still is to a certain extent) the Achilles heel of the whole EV world. Even now, at the start of 2016, signs are already there at charging stations. Vehicles take too long to charge, even with modern ultra-fast chargers, and their installation is 100% relying on the driver’s hooking and unhooking the plug for the car to charge. This brings to lines, frustration and an increased investment in infrastructure which results in chargers not being utilized to their full potential.

A new technology starts by first identifying the flaws in the existing technology, and addressing those flaws in ways that are as unique as possible. The innovations we identified and thus define HyperChargers are the following:

  • Ultra-Fast charging for batteries
  • Autonomous Vehicle Plug Engage/Disengage
  • Lower cost and low maintenance
  • Intelligent Charging Software

 

The Silex HyperCharger is an ultra-fast DC-to-DC charger that can fully charge battery packs in a matter of a few minutes. The technology involves both the physical charger, a proprietary connector and also modified battery packs with a highly specific BMS. The first generation of HyperChargers that will be launched in H2 this year will have a 600kW charging capacity and charge at 800V. It will connect via a proprietary connector, and will be able to charge the Valene Black Mamba’s 30kWh battery pack in less than 5 minutes. More powerful HyperChargers are to be launched in the coming years, with peak powers reaching 1.8MW. The latter will be able to fully charge the Chreos 200kWh battery pack in much less than 10 minutes, thus making EVs competitive with internal combustion engine cars when it comes to “fueling” time and range.

One crucial element that HyperCharging tackles is the removal of the inverter from the vehicle. This solution, not only decreases drastically the weight of the vehicle, but also its cost, allowing this technology to integrate easily into high-volume / low-cost electric vehicles of the future.

An important feature in the HyperCharger is the HyperCharger to Vehicle Communication Protocol – HVCP. The HVCP is a wireless communication system between the EV and the HyperCharger, and comes only second in innovation to the HyperCharger’s charging speed. The Valene Black Mamba, Chreos and future Silex vehicles will all be connected to a centralized processing centre. Same applies to HyperChargers. All installed HyperChargers will be geo-tagged and will allow cars that are equipped with a HyperCharging port to plan the route and plan necessary stops at fuel stations that have HyperCharging technology available throughout the journey as necessary.

This technology brings further convenience as the vehicle navigation software can even pre-book a charging station so that once the driver arrives to the station, he will know to which HyperCharger to attach his vehicle and thus optimise his time at the charging station. Once the car arrives at the HyperCharging station, a wireless signal will communicate with the HyperCharging station and engage in bidirectional communication. At this stage, the driver can authorise communication between the HyperCharging station and the vehicle from the vehicle control panel. This will immediately give the driver information about the charging time, charging cost and other necessary information that is available. At this stage the driver can select how much to charge the car (either a full charge, or a pre-determined charge based on time, availability or cost), confirm the charge and then just park the car in the station. HyperCharger will take care to connect to the vehicle automatically to engage in charging, and disconnect  once the charging cycle is complete.

At this stage, the charger software reconfirms all the necessary information with the vehicle and starts the charging process. The process of charging will also include battery pack and other vehicle component diagnostics, carry out software updates / adjustments if necessary and upload the information to the vehicle and the data centre. Upon charge completion, HyperCharger disconnects from the vehicle, and a message is sent to the driver indicating that the car is ready to continue with the trip.

Although HyperCharger utilizes voltages and connectors that are not industry standard, all Silex vehicles will be equipped with charging ports to maintain compatibility with the existing global charging infrastructure.

Silex HyperCharging technology is currently in the final stages of development and the first systems will be installed for testing purposes later on this year. Silex is open to third parties automotive manufacturers who are interested in adopting HyperCharging ports in their vehicles. For more information fill out the form below.
