Temperature Controlled Charger

Subcategory (under Clean Energy): Storage
Technology Readiness Level (TRL): TRL 4 - Early prototype
Technology Outline (Process Description)

The prototype developed is a 1.5kW rated conductive charger for Electric Vehicle and Electric boats in pilot locations like Ghoramara and Keonjhor. The main key components in this technology is power factor correction circuit to improve the power factor and buck converter to inject the current of magnitude 30A in continuous mode at 48V. Both the circuits in cascaded and connected by a DC bus 400V as depicted in Figure 20. EV battery pack to be charged are of 48V, 100Ah (4.8kWh Li-ion /Lead acid battery). Charging time is 3.5hrs (up to 0.3C). Battery Temperature will be estimated during Charging process.

Salient Features/Advantages

  • Temperature Regulation: The challenge faced by charging the vehicle (battery) are the proper regulation of the battery Temperature, Life and Charging time. Hence it controls the temperature of the battery. Battery Temperature will be estimated during Charging process. The key components in this technology are power factor correction circuit to improve the power factor. Capability of buck converter to inject the current of magnitude 30A in continuous mode at 48V
  • Charging Time: Charging time is 3.5hrs (up to 0.3C). Hence this charger provides fast charging rate which reduce the costs.

Key Outcomes

  • Providing Charging facilities to remote areas with advance features
  • Fast charging with temperature control charger is provided to remote areas
