Success Stories

  • Grasen released the 300kW to 420kW ultra-fast charger with Max. output current 400A can charge a vehicle battery up to 80% in just 15 minutes.

    420kW Ultra-fast Charger
  • As a local charging network operator, one of our customers from the Republic of Kazakhstan built this EV charging station with Grasen DC fast chargers, which are used to charge Tesla.

  • This charging station is located in North America. Customer ordered DC fast chargers with GB/T and CCS1 connectors.
