The 7 kW AC Vertical Charging Pile is Klitv’s floor-standing solution for open parking lots, roadside public charging, and commercial sites where wall mounting is impractical. Standing at 1,611 mm on a compact 133 × 265 mm footprint, the column design anchors directly to a concrete base and requires no supporting wall structure — enabling deployment in any outdoor parking area.
At 7 kW (220V, 32A), the vertical unit adds approximately 35–50 km of range per hour, fully charging most passenger EVs during overnight parking or a standard workday. Available in single-gun and dual-gun configurations, it can serve two parking bays simultaneously from a single unit — reducing the number of chargers and electrical connections needed per site.
Technical Design
Installation and Site Flexibility
The vertical column design eliminates the need for a wall mounting surface. The unit bolts to a pre-poured concrete plinth, with bottom-entry cable routing through the column base. This allows placement anywhere in an open parking lot — along kerb lines, between bays, or at the end of parking rows — without requiring building modifications or structural wall preparation.
The dual-gun configuration serves two adjacent parking bays from one unit. Power is shared between guns, with the full 7 kW available to a single vehicle or split across two simultaneous sessions when both bays are occupied. For site operators, this reduces the per-bay hardware and installation cost by approximately 30% compared to single-gun wallbox deployment.
Safety and Protection
The vertical charger incorporates the same comprehensive electrical protection suite as the wallbox:
- Built-in Type A RCD with 6mA DC leakage detection — IEC 61851-1 and IEC 62196-2 compliant
- Overvoltage and undervoltage protection with automatic recovery
- Overcurrent and short circuit protection with instantaneous cutoff
- Overtemperature monitoring with adaptive power reduction
- IP54-rated enclosure — tested for continuous outdoor exposure including rain, dust, and temperature extremes from -20°C to +50°C
Smart Charging and Load Management
OCPP 1.6J compliance enables integration with any OCPP-compatible CMS. Connected units participate in dynamic load balancing, automatically distributing available site capacity across all active chargers. For larger deployments, the CMS can schedule sessions during off-peak electricity tariff windows, reducing per-kWh energy costs without requiring driver behaviour change.
Use Case: Retail Car Park Charging
A typical deployment for a 200-space retail car park might consist of:
- 10× 7 kW vertical dual-gun units covering 20 premium EV-designated bays near the mall entrance
- OCPP CMS managing all 10 units from a single dashboard
- QR code payment enabling ad-hoc public charging without subscription or membership
- Dynamic load balancing preventing total draw from exceeding the building’s allocated EV circuit
Shoppers parking for 1–2 hours add 35–100 km of range during their visit — more than covering the round trip for most local customers. The dual-gun configuration doubles the number of EV bays served per charger, maximising the developer’s return on electrical infrastructure investment.
Deployment Specifications
Electrical Requirements
Each vertical unit requires a single-phase 220V supply with a dedicated 40A circuit breaker. For multi-unit installations, a dedicated EV distribution board is recommended. Cable sizing should account for the underground run length from the distribution board to each column base.
Civil Works
The 133 × 265 mm footprint requires a pre-poured concrete plinth or surface-mounted base plate. Cable entry is through the column base — conduit should be installed and capped before the plinth is poured. Foundation depth and reinforcement requirements depend on local soil conditions and frost line depth. Full civil installation specifications are provided with each unit.
