Protective bollards are rigid posts—typically made from steel or reinforced concrete—installed to physically protect assets from vehicle impact. In EV charging sites, bollards are commonly placed around charging stations, power cabinets, metering cabinets, and pedestals to reduce collision risk in parking areas and drive lanes.
Why Protective Bollards Matter in EV Charging Infrastructure
EV chargers are often installed close to traffic flow, parking maneuvers, and delivery routes.
– Prevents damage from low-speed vehicle impacts and parking errors
– Reduces downtime, repair costs, and charger replacement risk
– Protects electrical equipment and cables from mechanical stress and water ingress after impact
– Improves site safety for drivers, pedestrians, and maintenance staff
– Supports insurance, permitting, and site compliance requirements where impact protection is expected
Where Protective Bollards Are Typically Used
Bollard placement depends on site geometry and the type of equipment being protected.
– In front of wall-mounted chargers in garages and underground parking
– Around freestanding AC chargers on islands or at curb edges
– Protecting DC chargers and power cabinets in public hubs and service stations
– Near payment terminals, HMI screens, and cable management systems
– At high-risk corners, end bays, tight turns, and reversing zones
Key Design and Installation Considerations
Effective bollards must be designed for the expected impact risk and installed correctly.
– Setback distance so a vehicle hits the bollard before reaching the charger body
– Spacing to protect equipment while maintaining access for users and service teams
– Foundation depth and anchoring matched to site surface (asphalt, concrete slab, pavers)
– Visibility using reflective bands or high-contrast finishes for night and winter conditions
– Corrosion protection for outdoor and coastal environments
– Avoid obstructing cable reach, connector docking, and accessibility pathways
Types of Protective Bollards
Different bollard types fit different installation scenarios and risk levels.
– Fixed in-ground bollards for highest protection in exposed public sites
– Surface-mounted bollards for fast installation on existing concrete slabs
– Removable bollards where occasional vehicle access is required
– Sleeved / replaceable-core designs to simplify repairs after an impact
– Flexible bollards mainly for guidance and visibility, not for high-impact protection
Integration With EV Charger Layout and User Experience
Poorly placed bollards can reduce usability, so they must be considered early in site design.
– Maintain safe pedestrian routes and ADA / accessibility clearances where applicable
– Ensure drivers can park and access the connector without awkward angles
– Leave space for maintenance access, door openings, and ventilation clearances
– Coordinate with bay marking, kerbs, wheel stops, and signage
Limitations and Risks to Consider
– Incorrect anchoring or shallow foundations can cause bollards to fail on impact
– Overuse or tight spacing can hinder accessibility and create trip hazards
– Flexible bollards may not provide real equipment protection in vehicle strikes
– Bollards do not replace proper traffic design, speed control, and clear signage
