| Solution Feature |
- Our Smart EV Charging management solution connects OCPP 1.6 / OCPP 2.0 complaint AC/DC chargers through diversified network configurations. Using real time monitoring and powerful charging algorithm to balance among chargers, optimizing charging efficiency and reduce power installation cost.
- It dynamically monitor, compute and distribute power among chargers according to Charge-Time and Energy, charging priority, EV response time, using EV-Linear algorithm through: 1.Charger ON / OFF (13A) 2.Charger Current (AC and DC charger) Power Phase change (13A and AC Charger) with additional Hardware.
- No limitation in number of chargers, can reduce maximum 70% of installation cost and increase 300% effectiveness without additional hardware. The system monitors loading on all power phases and dynamically adjust output current to EV, using PWM technique for AC chargers and reduce output current directly for DC chargers.
- System management monitor networked EV chargers through internal Ethernet/MODBUS or through mobile network to backend/cloud system. Since the system support all types of EV chargers, this load balancing system support different types of chargers and different Charge Point Operators (CPO) in car park setup.
- Function under network failure scenario through stringent operating framework, delivering charging current with margin and ensuring installed AC capacity never be exceeded. Our load balancing algorithm can take on-site electrical installations e.g. boilers, chillers, A/C AHU consumption status, through IoT sensors to further optimize charging efficiency and user experience.

| Trial Application and Expected Outcome |
- Propose a pilot demonstration system consisting of our Smart unit and 9 sets of 7.4KW/22 kW chargers, using a 32A 3 phase power source to be constructed at EMSD's designated site.
- While our solution has been proven with global and mainland service providers, optimization and value added features would be added to this trial implementation for meeting local regulations and customer specific requirements
- We plan the project consist of Design / Construct / T&C stages including performance measurements and reporting of below but not limited to : 1. 1 and 2 EV on same phase 2. 3 EV on same and different phases 3. up to 9 EV concurrent charging
- We plan boundary and fault condition testing include but not limited to 1.Network disconnection 2. Non-compliant EV 3. Environmental variations
- We plan trial features planned 1. System power / system performance on host / dash board 2. EV charger status and fault reporting log on system cloud 3. Real time APP-Free alert to service provider / customers
