The numbers of electric vehicles („EV”) are expected to grow rapidly in the upcoming years, therefore the demand for stations having electric fast charging capability is also expected to increase. CTT plans to capitalize on this market phenomenon by offering state of the art solar (fast) charging station.
Most EVs have an on-board charger that uses a rectifier circuit to transform alternating current („AC”) from the electrical grid to direct current („DC”) suitable for recharging the EV’s battery pack.
In AC charging systems, the car has an on-board charger which performs the AC to DC conversion. In DC charging systems, there is an off-board AC to DC converter for the AC-DC conversion, and there’s a direct connection to battery pack bypassing the on-board AC charging system. DC fast charging is currently the fastest electric car charging system available. Currently there are four DC fast charging technolgy used by electric car manufacturers:
1. CHAdeMO: CHAdeMO is a DC charging protocol currently enabling EV charging with power from 6kW to 60kW, its theoretically will be capable for 150kW. The protocol was defined by an association with the same name. CHAdeMO association was formed by The Tokyo Electric Power Company, Nissan, Mitsubishi and Fuji Heavy Industries. CHAdeMO technology is a form of DC fast charge, for high-voltage (up to 500 VDC) high-current (125 A) automotive fast charging via a JARI DC fast charge connector. The connector is specified by the JEVS (Japan Electric Vehicle Standard) G105-1993 from the Japan Automobile Research Institute. CHAdeMO ports does not support AC charging, therefore cars must have two ports (one for AC and one for CHAdeMO).CHAdeMO is currently the most popular standard, it passed the 10,000 land mark in the number of installed stations, in late 2015. In the US near three quarters of DC charging systems is related to this protocol.
2. Combined Charging Systems: The Society of Automotive Engineers („SAE”) developed its own DC fast charging protocol, the Combined Charging Systems („CCS”).
Unlike CHAdeMO CSS uses a single port to support both slow and fast charging (AC and DC charging). The plug used is basically the J1772 plug (used for AC charging) with the additional large pin for high power DC.
CCS also offers higher potential rate of charge than CHAdeMO. While existing CCS chargers typically run at the same speed as CHAdeMO, the standard allows for a theoretical maximum of 350 kW.
CSS protocol was introduced relatively late (the first public test station was installed in 2013). Since then there has not been significant progress in the increase of station numbers, CCS stations installed in the US account for less than 400. CCS is usually provided alongside CHAdeMO within the same station.
CTT will produce two product types:
Home EV charging: EV charging for home usage
Commercial EV charging: Commercial EV charging includes charging of automobiles and also autobuses, as a part of project TOSA (Trolleybus Optimisation Système Alimentation). CTT plans to take part in project TOSA together with ABB. The project includes the fast charging of autobuses – accumulators can be charged within 15 seconds at the bus stops. Beside assuring a flexible route for the means of public transport, it can also substitute the overhead cable system.
Solar modules and the rack system is produced by CTT. Other components are purchased from the suppliers.
CTT focuses on a niche market, with its product portfolio. The main market players can be mentioned as competitors. However, the Company plans to create a close business relationship with these markets player by selling and purchasing components to and from them.
Targeted markets and players
CTT aims to discover new market opportunities and identified three potential market segments:
Retail chains: solar charging stations can be installed in the parking area of retail stores.
P+R parking: Municipalities aiming to reduce the environmental impact, and bus operators or railway operators aiming to have more passengers by offering charging opportunities. The number of electric autobuses are expected to grow significantly in the next years. CTT plans to sell a significant portion of its products to this segment, as at least 7 charging station is required within a 10 km long route.
Procurement CTT plans to purchase the components from ABB, Tesla, MAXWELL, Chademo
5 Reasons why EV Chargers are perfect for shopping centres
1) People often spend upwards of an hour at a shopping centre.
2) Attract EV drivers to return to the shopping centre.
3) Attract EV drivers to spend even longer than they otherwise would at the shopping centre.
4) Attract EV drivers on road trips or passing through a suburb who might otherwise not go to the shopping centre to stop and charge.
5) Promote Green Credentials of the business and their Corporate Social Responsibility through increased media attention and publicity.
