How to deal with network failures when using an electric vehicle charger

How to Handle Network-Related Issues When Using Electric Vehicle Chargers
Network connectivity plays a crucial role in modern electric vehicle (EV) charging, enabling features like remote monitoring, payment processing, and real-time updates. However, network outages or instability can disrupt these functions. Below are practical strategies to manage network-related problems during EV charging sessions.

1. Understanding Common Network Issues During Charging
Network problems can range from temporary outages to intermittent connectivity, affecting both public and private charging stations. Identifying the root cause helps determine the right solution.

• Weak Wi-Fi or Cellular Signals: Many charging stations rely on internet connections to communicate with EVs or backend systems. If the signal is weak, the charger may fail to authenticate or start sessions.

• Server Overloads or Maintenance: Charging networks occasionally experience downtime due to high traffic or scheduled updates, preventing users from accessing services.

• Local Network Restrictions: Some locations, like underground parking garages or remote areas, may lack stable internet access, leading to authentication failures or delayed data syncing.

2. Steps to Take During a Network Outage While Charging
If the charger loses connectivity mid-session, follow these actions to avoid interruptions or complications.

• Check the Charger’s Status Lights: Most chargers display error codes or warning lights when network issues arise. Refer to the user manual to interpret these signals and confirm if the problem is network-related.

• Retry Authentication Manually: For public chargers requiring RFID cards or mobile apps, try restarting the authentication process. Some systems store limited offline functionality, allowing sessions to continue once connectivity is restored.

• Monitor Charging Progress Locally: If the charger’s display shows real-time data, use it to track energy transfer instead of relying on a paired smartphone app. This ensures you stay informed even without internet access.

3. Alternative Solutions for Network-Independent Charging
When network issues persist, leverage backup methods to complete or initiate charging sessions without relying on external connectivity.

• Use Chargers With Offline Capabilities: Some advanced chargers can operate in a “standalone” mode, storing session data locally and syncing it later when the network recovers. Check if your charger supports this feature.

• Switch to a Different Payment Method: If the network outage affects digital payments, look for chargers that accept contactless cards or prepaid tokens as alternatives.

• Plan Charging Sessions During Low-Traffic Periods: Network congestion is often higher during peak hours. Scheduling charges during off-peak times reduces the likelihood of encountering server-related delays.

4. Preventative Measures to Minimize Network-Related Disruptions
Proactive steps can reduce the impact of network issues on future charging sessions.

• Keep Software Updated: Regularly update your EV’s infotainment system and the charger’s firmware to ensure compatibility with the latest network protocols and security standards.

• Carry Physical Authentication Tools: Always have a backup RFID card or key fob for public chargers, as these may work even when mobile apps fail due to network problems.

• Test Connectivity Before Long Trips: If relying on public charging networks during travel, verify coverage in your route’s key areas using the provider’s website or app. This helps avoid locations with known connectivity issues.

By staying informed about network limitations and preparing for outages, EV owners can ensure smoother charging experiences even when connectivity is unreliable. Prioritizing chargers with offline features and maintaining backup authentication methods further enhances resilience.
