DC Stationary Chargers

Medha Chargers offers a range of advanced charging solutions for electric buses. Our mobile charger is a cutting-edge device designed to transform 3-phase 400 V AC voltage into adjustable output voltage, ranging from 400 V to 1000 V.

Implementing the appropriate charging infrastructure is essential to ensuring the efficient operation of electric buses. Medha offers both mobile and stationary chargers designed for electric bus batteries. Medha’s stationary city chargers are mounted on a concrete foundation and powered directly from the industrial network with a 3 x 400 V AC voltage.


Key Features
  1. Versatile Charging: Supports simultaneous charging of two vehicles with a maximum battery charging power of 30kW and 75kW, respectively. Alternatively, it can charge a single vehicle with up to 120 kW or 150 kW.
  2. Intelligent Operation: The charger automatically selects the operating mode based on the use of CCS2 connectors, ensuring optimal charging efficiency.
  3. Easy to Use: The charger starts working automatically upon connecting the CCS2 plug to the bus, eliminating the need for manual intervention.
  4. Customizable: Can be configured with additional features like energy meters, RFID readers, and 2.4″ displays to meet specific requirements.
  5. Robust Design: IP54 protection rating ensures durability and reliability in various environmental conditions.
  6. Advanced Communication Protocols: Supports multiple communication protocols, including IEC 61851 and ISO 15118, for seamless integration with different charging infrastructure and vehicle systems.
  7. Efficient Cooling: Air-forced cooling system ensures optimal thermal management, preventing overheating and extending the charger’s lifespan.

Medha Chargers is committed to providing reliable, efficient, and sustainable charging solutions for electric buses, contributing to a cleaner and greener future.
