High Speed AC & DC Chargers

  • GARC Charging Stations support all international & Bharat EV-EVSE communication protocol.
  • GARC is equipped with the following Charging Stations
    • 3 Numbers of Bharat AC001 – 3.4 KW
    • 3 Numbers of Fast Charger Bharat DC001– 15 KW
    • 3 Numbers of Ultra Fast Charger GB/T – 120 KW
    • 3 Numbers of Ultra fast CCS/ CHAdeMO charger – 150 KW
  • Ultra high speed charging stations like GB/T, CCS type 2, Chademo, AC type 2 can charge the vehicle in less than one hour. Fast charging station like Bharat DC 001 can charge the vehicle in about one hour duration and slow charging station like Bharat AC001 take more charging time. The chargers can be cloud monitored for consumption, SOC & internal parameters.

Vehicle Test Bench

  • Electrical Vehicle level performance tests for 2W, 3W & 4W can be carried out in chassis Dynometer with temperature soak room facility.
  • Tests like Electrical Energy consumption, Vehicle Range, Net Power, SOC based Gradability, Regeneration and Component Efficiency Evaluation can be carried out.
  • Vehicle Certification & Standard endurance drive cycle testing can be carried out according to different regulations or customer defined drive patterns.
  • Real time data logging of electrical parameters like voltage, current, power, temperature of all EV components (battery, controller and motor) during chassis dyno drive conditions.

Electrical Protection against Voltage Contact  & IP Ingress

  • GARC is equipped with Voltage Contact Probe B & probe D to check the protection against electric shock if passengers are exposed to any direct electric contact in the vehicle.
  • Similariy IP Ingress water gun (IPX 3 & IPX 5) are utilized to simulate heavy rainstrom condition and vehicle water wash condition in electric vehicle & to check any insulation failure occurs in the EV’s when components are exposed to water ingress.
  • Also is available water wade track to simulate road flooding conditions. Accordingly when the vehicle is driven in flood conditions, the vehicle’s insulation are monitored to meet safety standards
