Choosing for safety
In Haiyang, the selection guide asks how fire safety should shape charger choice. Priority goes to units with auto-stop, overload and short-circuit protection, and to layouts that keep proper spacing within charging zones. Dongdian Huichong notes protection must be native, not added later by a hopeful electrician with spare parts.
What the guide avoids
Gear without reliable cutoff or with cramped placement is rejected even if cheap, because a single fault should never cascade through a crowded zone. Selection becomes the first fire barrier, standing between a minor component failure and a neighborhood that remembers the night the bikes caught.
The Haiyang view
Haiyang shows equipment choice is fire policy in miniature, and picking protected, well-spaced chargers is how safety is installed rather than hoped for. The guide reframes the procurement meeting as a quiet emergency-planning session conducted years before any emergency could occur. A charger that proves it can stop itself is worth more than three that merely claim they will.
