Installing EV Chargers in Parking Lots: A Complete Operator's Guide

Parking lots are becoming one of the most important battlegrounds in the EV charging rollout. Whether it's a shopping center, a municipal car park, or a private operator — adding EV charging creates new value for every parking space. Here's a practical guide to getting it right.

Planning Your Parking Lot Charging Deployment

Start with a site assessment: evaluate available electrical capacity, cable routing options from the main panel to parking bays, and which spaces should be prioritized. High-visibility, accessible spaces closest to entrances typically get the most use and generate the best ROI.

Charger Selection for Parking

For parking lots, 7.4kW or 11kW AC chargers are typically the right choice — fast enough for vehicles staying 1–4 hours, and far less expensive to install than DC fast chargers. For high-turnover short-stay parking, 22kW or DC fast chargers may be warranted. All chargers should be OCPP-compliant to enable central management through Greems.

Load Management is Non-Negotiable

In a parking lot with 10, 20, or more chargers, unmanaged simultaneous charging would overload any standard electrical connection. Greems' dynamic load balancing distributes available power across all active sessions in real time — preventing overloads while maximizing throughput. This is what makes large-scale parking lot deployments economically viable without expensive grid upgrades.

Monetization Options

Greems supports flexible pricing: per-kWh, per-hour, flat session fee, or free with validation. Payment can be handled via app, RFID, or QR code. Real-time session data flows into automated invoicing — zero administrative overhead for the parking operator.
