A city block with forty parking bays and three EV drivers circling for a plug is the challenge for planners weighing how to add charging without tearing up the pavement. The choice usually comes down to two paths: scatter simple curbside plugs along the curb, or install a compact on-street EV charging hub, such as the units built by INFORE ENVIRO, that serves several vehicles from one footprint.
Both approaches keep cars charged overnight or during a shopping trip, but the engineering differences are significant enough to affect how a street performs once the equipment goes live.
Curbside Plugs: What They Solve and Where They Fall Short
Curbside plugs are usually single-gun AC units bolted to a post or wall, wired to draw a limited current from the building’s existing supply. They fit the sidewalk without much civil work, which is why cities relied on them heavily during early EV rollout years.
The drawback shows up during peak hours: a 7kW plug can take most of a workday to bring a battery from low to full, so a single space is effectively locked for hours. Add a broken connector or a card reader that only accepts one payment network, and the space becomes unusable until a technician arrives.
For low-turnover residential streets this is tolerable; for retail strips, hotel drop-offs, or fleet depots where vehicles need to turn over faster, it becomes a bottleneck that shows up in complaints before anyone reviews the usage data.
AC DC Charger Hubs: A Different Way to Handle On-Street EV Charging
An AC DC charger changes the equation by putting two charging methods in one cabinet. Instead of choosing between a slow AC plug and a costly standalone DC fast charger, a hybrid unit lets an operator serve a car that needs a quick top-up through the DC gun while a second vehicle parked longer draws from the AC gun.
This dual-mode design is what makes hybrid units well suited to mixed on street EV charging scenarios, where dwell time on any given street varies from ten minutes to several hours depending on the driver’s errand.
INFORE ENVIRO’s DC60kW+AC22kW Vector Series AC DC charger illustrates how this works in practice. The floor-standing unit pairs a 60kW DC output (CCS2/CCS1, rated up to 200A) with a 22kW AC output (Type2, 32A) on two separate guns, so both charging speeds run from a single housing rather than two separate installs.
A 10.1-inch touchscreen handles authentication through APP, RFID card, or optional POS, and the unit connects over 4G, Wi-Fi, Ethernet, or Bluetooth to a cloud platform running OCPP1.6J, with OCPP2.0 available as an option, a detail worth checking against any existing back-office software before ordering equipment for a multi-site rollout.
Compatibility with roughly 99% of EV models on the market also matters on a public street, where an operator rarely controls which vehicles show up to charge.
Built for Outdoor Duty
Street-facing hardware takes weather exposure that indoor chargers rarely see, so protection ratings matter more here than in a parking garage. The Vector Series carries an IP54 rating and an operating range of -20 degrees C to +50 degrees C, with protection against short circuit, overload, over-temperature, leakage, and overvoltage conditions.
Scheduled charging, smart charging, and DLB dynamic load balancing let an operator cap total site draw during grid peak hours, a factor that matters when several units share one transformer along a commercial strip. Remote upgrades and diagnostics also cut down on truck rolls, since a support team can push a firmware fix or flag a fault from the same cloud platform.
Weighing the Two Against Site Data
The right pick depends less on brand preference and more on how a specific street behaves. A residential block with predictable overnight parking rarely needs anything beyond a basic AC plug, and the lower install cost suits low-traffic settings well.
A commercial corridor, hotel frontage, or destination retail site with unpredictable dwell times benefits from a hybrid AC DC charger, since it avoids installing two separate cabinets, two separate permits, and two separate maintenance contracts to cover both fast and slow charging needs on the same block.
Municipal planners running curbside pilots often start with plug counts and traffic studies, then size the hybrid units to the busiest blocks rather than deploying one format citywide, which keeps the budget focused on locations where turnover actually justifies the extra DC capacity.
Sourcing Equipment for Mixed-Use Streets
Hardware choice affects far more than charging speed. After-sales support, certification coverage, and manufacturing consistency determine whether a rollout stays reliable past year one.
INFORE ENVIRO operates from Shunde, Guangdong as a core subsidiary of Infore Group, listed under stock code 000967, running dual R&D centers across Shunde and Shenzhen with more than ten years in the charging equipment sector.
Matching Infrastructure to the Parking Reality
Curbside plugs and hybrid hubs both belong on the street; the question is which segment of a route needs which format. Where dwell time swings widely and equipment has to justify its footprint, a compact AC DC charger tends to outperform a row of single-purpose plugs, since one cabinet covers both charging speeds a mixed-use block actually sees.
