The electrical installation of a building is designed to the extent that it is able to afford the maximum electrical consumption from daily common usage. In reality, you seldom use up this power, actual power consumption is different against 24 hours of a day. This can be interpreted into an electricity consumption curve as Power Profile. For a residential building, maximum consumption could be seen at night while a dramatic drop is in the daytime when everybody goes for work. Most of the time, the maximum power consumption does not tough the power ceiling and leaves a certain extent of potential power which is “idle”. Harness this idle power to charge EV will definitely be of great benefits.
The green curve represents the actual power consumption against 24 hours of a day. Below is the curve of the difference between building’s electrical supply ceiling and the green curve representing the residual power not in use, looking like the “shadow” of the green curve. This is the Shadow Power we can harness for EV charging.
Monitor and harness Shadow Power in real time dynamically is a sheer technical task. Our PSN-EVC System is able to capture 90%+ of the Shadow Power in an existing circuit while guarding the set limit within safety threshold.
The following graphic shows that an average of as high as 90% of Shadow Power has been harnessed to charge 4 EVs in a car park at the same time, perfectly manifesting the capability of the system of keeping the power ceiling precisely and dynamically.
Our R&D and Engineering Teams are formed by a group of the best experts in the field of smart control of electrical power. Leader is former chief-engineer of the local power company, among the very few experts in Hong Kong who design, install and maintain the whole power grid for decades.
We are the Expert Team you need.
Our unique PSN-EVC System is deliberately developed for the management of EV load and the Shadow Power under the core control algorithm "NALA", the most advanced and reliable patented smart power control mechanism which has been shared by successful IOT solutions.
PSN-EVC is the Expert System you need.
