Shadow Charging & Adaptive Charging
Great minds think alike, especially with the same objective to bring benefits to the whole society. In recent years, there is a load management system developed by CALTECH in US called “Adaptive Charging” rising in the western market. We found that this system shares the similar idea with us on the use of existing underutilized power of a car park for smart EV charging. Visit Adaptive Charging Network.
Mutually developed on own efforts, shadow charging & adaptive charging both deal with the problem of large upfront cost of power upgrade and the poor energy efficiency of individual charging station. Adaptive charging adapts to the power consumption pattern of a building and harnesses existing unused power to support connected charging stations with controllable load. This is exactly the new concept we are also bracing for. Same power source, similar concept, different algorithm and networking infrastructure, let’s take a look at a simple comparison between this two smart charging systems.
