How Mesh works
No engineering degree required. Here's what actually happens when someone plugs in their car.
What the Hub does
The Hub lives in your building's electrical room and watches how much electricity the whole building is using at any given moment. When total usage is high — say, dinner hour when everyone's home and cooking — the Hub tells the chargers to slow down a little. When usage is low, chargers run at full speed. The Hub makes this decision thousands of times per day, automatically, without anyone touching anything.
What the Edge does
The Edge is a small device installed between the electrical panel and the EV charger in each stall. It receives instructions from the Hub over a low-power wireless signal — the same kind used in commercial building automation systems — and adjusts the charge rate accordingly. The EV charger itself is unchanged; the Edge just tells it how fast to go.
What "load management" actually means
Your building has an electrical service — a maximum amount of electricity it can draw from the grid at any one time. That limit was set when the building was built, based on expected usage. EV chargers weren't part of that calculation.
If every unit owner plugged in their car at 6pm and drew full charging power simultaneously, the building could exceed its service limit — causing breakers to trip, BC Hydro to impose penalties, or in older buildings, real safety problems.
Load management means Mesh watches the total draw and makes sure it never gets close to that limit. In practice, this means chargers occasionally run at 80% instead of 100% for an hour. In practice, it means your car is still fully charged by morning.
Mrs. Wong's version: the system makes sure everyone gets their car charged without the building blowing a fuse. It works quietly in the background. You plug in, you wake up, your car is charged.
