How to Safely Use Public DC Fast Chargers
Last updated: October 2025
Essential safety tips and best practices for using public DC fast charging stations, including connector handling, payment security, and emergency procedures.
Safe DC fast charging requires: Pre-charging safety inspection, proper connector handling, secure payment methods, and knowledge of emergency procedures. Always inspect equipment before use and never force connections.
Before plugging in, always perform these safety checks to ensure a safe charging session.
Equipment Inspection
- •Inspect charging cable for damage, cracks, or exposed wires
- •Check connector is clean and free of debris or corrosion
- •Ensure charging station display shows no error messages
- •Verify station is not damaged or vandalized
Vehicle Preparation
- •Park properly within designated charging space
- •Turn off vehicle completely before connecting
- •Engage parking brake and turn off all accessories
- •Open charging port and check for obstructions
Personal safety on site
Choose well-lit locations with clear visibility. Keep cable slack tidy to avoid trip hazards. Keep valuables out of sight and stay aware of surroundings. Report vandalized or suspicious equipment to the network/site host.
Correct connector handling prevents damage to your vehicle and ensures safe charging.
| Step | Action | Safety Note |
|---|---|---|
| 1. Grip | Hold connector by handle, never the cable | Prevents cable damage and ensures control |
| 2. Insert | Insert firmly until click/lock | Ensures proper electrical connection |
| 3. Check | Verify charging has started | Confirms successful connection |
| 4. Disconnect | Stop the session via the app or station first, wait for the connector to unlock and the contactors to open, then unplug straight out—do not twist or yank | Prevents electrical arcing |

Never Force Connections
If a connector doesn't fit easily, stop immediately. Check for compatibility issues or contact station support.
Use certified connectors & adapters
If you use an adapter (e.g., J3400/NACS ↔ CCS), choose products listed to relevant safety standards (e.g., UL 2252 for adapters; UL 2251/2594/2202 for EVSE). Avoid homemade or uncertified adapters.
Protect your personal and financial information when using public charging stations.
Secure Payment Methods
- •Prefer Plug & Charge when available to reduce time at payment terminals. Otherwise use official network apps or tap-to-pay.
- •Use contactless payment (tap-to-pay, mobile apps)
- •Prefer official charging network apps
- •Cover PIN when entering on payment terminals
- •Monitor credit card statements regularly
Security Best Practices
- •Avoid damaged or suspicious payment screens
- •Never share charging account credentials
- •Use strong, unique passwords for charging apps
- •Report suspicious payment activity immediately
Know what to do if something goes wrong during your charging session.
Electrical Emergency
- • Press emergency stop button immediately
- • Move away from the charging station
- • Call emergency services (911)
- • Do not touch any equipment or cables
- • If the vehicle or charger is damaged (collision, flood, smoke/odor), do not attempt to charge. Move away and contact emergency services and your vehicle's support.
Stuck Connector
- • Do not force or pull the connector
- • Contact charging network customer service
- • Use vehicle's manual release if available
- • Wait for professional assistance
Equipment Malfunction
- • Stop charging session immediately
- • Report issue through station app or phone
- • Take photos of error messages
- • Move to another charging station if available
Adapt your charging approach based on weather and environmental conditions.
Wet Weather Precautions
- •It's safe to charge outdoors in rain with outdoor-rated equipment. Avoid standing water and do not use damaged gear.
- •Do not plug in if the connector/port is submerged or severely contaminated (mud, ice, debris). Wipe off heavy moisture; never force a connection.
- •Use covered bays when available; walk carefully on wet surfaces.
Cold Weather Safety
- •Allow extra time for charging in cold weather
- •Check for ice formation on connectors
- •Precondition battery before charging
- •Wear appropriate footwear for traction
