创新及科技解决方案

1. ev Chargers of various types (AC/DC), socket types, mounting method, power output (from 7kw to 350kw) to satisfy requirements of different car parking environment serving both home charging and destination charging requirements. Medium chargers can be installed in government building to serve the charging needs of their fleets of electric vehicle. High power (super/ultra fast) chargers can be installed in public area to provide immediate charging services to citizens.

2. Use of common OCPP 1.60 (Open Charge Point Protocol version 1.6), an application protocol for communication between EV charging station and a central management system. It supports smart charging control and management, load balancing, multi-payment, big data sharing, JSON client/server communication protocol for more secure and faster connection. In particular, (a) For charging station owners, it provides greater choice and flexibility; (b) For users, the protocol encourages charging stations to compete on price, service, product features and innovation; (c) for city planner, it makes it easier to create a large-scale, visible network; (d) for developer, it reduces the development costs since software that provides additional functionality would only need to be developed once.

3) Flexible payment system that supports both membership (in apps registration) and non-membership via payment kiosk. The charger is Octopus type-test approved and can support other payment gateway, e.g. Fast Payment Service, through integration. It’s future proof and allows the site operators, including HKSAR Gov’t, to recoup the cost of the charging services, esp in future when more EVs will come into the market. Payment in public car park will be inevitable but become acceptable.

4) Mobile Apps supports added features such as location search, charger status monitoring, remote charger reservation, in-apps payment, QR Code scanning, order status monitoring and etc. It makes charging smart and hassle-free, reduces the range anxiety of driver and facilitates the achievement of smart mobility of HKSAR Gov’t smart city development project.

5) "Snapcharge" Control and Management Platform allows user management, order management, payment transaction management, power consumption (kw/Amp/Volts) recording and analysis, charger/charging station monitoring and etc. It enables real-time monitoring of the charger and operation status for better after-sales management. The operator can generate report for analyzing the performance for better planning.

6) Load Management Controller maximizes the availability of charger by different algorithms, e.g. even distribution, queue, dynamic, which is particular suitable for old/existing building where power grid is always not sufficient to serve power input needs of all chargers in the same car parking space. It facilities the charger installation and adoption of more electric vehicle which is more environmental friendly since it has tail pipe to emit air polluted gas.

Remark: the proposed solution will focus on the demonstration of Platform, App and Load Management.
