Retail businesses should place chargers within sight lines of storefronts to encourage browsing while charging.

Electrical Capacity Assessment

Most commercial Level 2 charging stations require dedicated 40-100 amp circuits. Facilities must verify existing electrical service capacity accommodates additional load. Buildings with 200-amp or smaller service panels typically require utility service upgrades costing $5,000-$25,000. Load management systems can optimize existing capacity by distributing power across multiple charging ports based on demand.

Parking Space Requirements

Standard charging spaces measure 9 feet wide by 18 feet deep, though 10-foot widths improve accessibility. Designate spaces with clear signage and pavement markings to prevent internal combustion engine (ICE) vehicle parking. Some jurisdictions allow enforcement through parking violations, while others require businesses to implement private enforcement policies.

Equipment Specifications

Charging Station Types

Networked charging stations connect to cloud-based management platforms, enabling remote monitoring, usage tracking, and dynamic pricing. Non-networked units offer lower upfront costs but lack data analytics and remote management capabilities. Most commercial applications benefit from networked solutions despite 15-25% higher initial costs.

Key Features

Power Output: Commercial installations typically deploy 7.2 kW (30-amp) or 11.5 kW (48-amp) chargers. Higher output reduces charging time but increases electrical infrastructure costs. Match power output to expected dwell times—7.2 kW suits 4-8 hour parking, while 11.5 kW accommodates 2-4 hour visits.

Smart Charging Capabilities: Load management distributes available power across multiple ports, preventing electrical system overload. Time-of-use scheduling shifts charging to off-peak hours, reducing demand charges by 30-50%. Integration with building management systems optimizes total facility energy consumption.
