Robot & AGV Charger (CC-CV) Selection in 5 Steps
From pack spec to fleet rhythm — how to specify charging power so robots are ready when the shift starts.
01Step 1 · Start from the pack spec, not the charger catalog
Three parameters first: chemistry (lead-acid stages vs lithium CC-CV), series count (sets full-charge voltage), capacity (sets current and charge time). Without these, any charger quote is guesswork.
02Step 2 · CC-CV is the baseline for lithium
Safe lithium charging is constant-current then constant-voltage. The switchover point and taper current decide how full, how fast, and how much the pack ages. The CC-CV profile must be defined by the pack spec — never "a charger rated about the same voltage".
03Step 3 · Size power by fleet rhythm
A single small pack needs a few hundred watts; what matters is the fleet: shared bays, return-to-charge interval, required turnaround. Our CH charger series spans 100W–3kW — from onboard top-up to centralized fast-charge rooms, one series as the fleet grows.
04Step 4 · Unmanned rooms need communication
Charging is mostly unattended: CAN or RS485 reporting of state and faults puts every bay on the dispatch screen. CH series offers both interfaces — choose per your fleet-management system.
05Step 5 · MEAN WELL NPB users: cross-reference
NPB (intelligent battery charger, lead-acid/Li-ion) maps to our DZ-CH series at application level — the CC-CV profile and connectors are defined by your pack spec, confirmed by engineering per inquiry. Not a drop-in swap promise.
