What does it mean when charger goes to SuspendedEV status? – SWTCH

When an EV charger displays a "SuspendedEV" status, it essentially means that the charger is providing power, but the electric vehicle isn't currently accepting it. Here's a breakdown of the common reasons:

Reasons for "SuspendedEV" Status:

Battery Reached Full Charge:
- The most frequent cause is that the EV's battery has reached its maximum charge level. The car's battery management system (BMS) then signals the charger to stop delivering power.
Battery Management System (BMS) Control:
- The BMS plays a crucial role in regulating charging. It might suspend charging due to:
  - Temperature: If the battery is too hot or too cold, the BMS may pause charging to protect it.
  - Voltage fluctuations: The BMS is constantly monitoring the health of the battery, and may suspend charging if it detects any problems.
  - Balancing: The BMS might temporarily suspend charging to balance the charge levels of individual battery cells.

Scheduled Charging:
- Some EVs allow you to schedule charging sessions. If you've plugged in your car before the scheduled time, the charger might enter a suspended state until the designated charging period begins.
Vehicle-Specific Settings:
- Certain EVs have settings that allow you to limit the maximum charge level or control charging behavior. These settings can trigger a "suspendedEV" status.
Communication Issues:
- Occasionally, there can be communication glitches between the charger and the EV. This can lead to the charger misinterpreting the vehicle's status and displaying "suspendedEV."

In simpler terms:

Think of it like filling a glass of water. Once the glass is full, you stop pouring. Similarly, when an EV battery is full, it stops accepting electricity. The "suspendedEV" status indicates that the "pouring" (charging) has been paused because the "glass" (battery) is full, or that the car has decided that it does not want any more water right now.
