Why do EV charging stations overheat?

Fast charging
The primary heat generation is fast charging, especially when converting electrical current from AC to DC. Today, vehicles have greater capacity for fast charging, but special care must be taken to control temperature in the charger and battery. Heat is the worst enemy of electrical components, and they must operate in the recommended range from the supplier.

Problems generated by overheating
  • Electronics' lifespan is reduced when working at high temperatures for long periods.
  • Safety and overheating may cause a fire, an extremely dangerous situation for your equipment and the people around.
  • Time to charge, the system can entry in pause, reduce the velocity of charging, or completely stop.

  • How to protect from overheating
    Chargers can be installed inside; if that is the case, the ambient temperature where the charger is installed must be kept at a safety margin, do not let the heat accumulate and rise the temperature, and the room should have proper ventilation. If the charger is installed outside, protect it against direct sunlight.
    Some applications require the installation of air-to-air heat exchangers that quickly dissipate the excess heat to the atmosphere. Ask one of our experts for more information about our technology and how to protect your equipment from overheating.
