Opportunity Charging
Engineering reference on Opportunity Charging for wireless power system design, integration, and deployment.
Opportunity charging exploits dwell time that already exists in the workflow. An AMR waiting at a pick face for the next order, an AGV buffering at a conveyor handoff, or a robot parked during a batch change — each idle window can deliver coulombs if a pad is within navigation reach.
Wireless opportunity charging removes friction: no manual plug-in, no pin wear, and fast engagement when dock alignment is engineered into the station layout.
01Where opportunity pads pay off
- High-traffic pick-and-place stations with predictable dwell exceeding alignment plus ramp time.
- Loop routes with natural pause points near the end of each cycle.
- Buffer zones where robots queue anyway — charge while waiting for downstream capacity.
- Shift-boundary staging areas where robots idle before the next wave dispatches.
02Design constraints
Opportunity windows are short — seconds to a few minutes — so load detect, frequency tracking, and power ramp must settle quickly. SiCore fast-start dock firmware pre-biases resonant frequency from the last successful mate at that pad and uses staged ramp profiles tuned for partial SOC top-offs rather than full CC/CV cycles.
03Fleet software coordination
Not every idle moment should trigger charging: the fleet manager balances opportunity top-offs against pad wear, thermal accumulation, and mission urgency. SiCore APIs expose pause/resume and max-power caps so schedulers inject charge only when SOC margin and dwell time justify the dock overhead.
