Translating technology into sustainable solutions
At Medha, our commitment to environmental sustainability drives every aspect of our operations. We are dedicated to reducing carbon emissions through innovative technologies. Committed to Sustainable Development Goal 9 on Sustainable Transport, Medha invests significantly in research and development, with a research team of over 700 members. We have already achieved notable results, enhancing rail network efficiency through advanced in-house signalling systems, efficient suite of propulsion systems, revamping old rollingstock for enhanced propulsion efficiency, and converting diesel locomotives, mining trucks, and buses to zero-emission battery power. As part of our ongoing investment, we are building hydrogen powered trains slated for upcoming trials. Medha also develops converters for commercial solar plants and is part of the sustainable energy ecosystem solution providers.
Explore the various sectors our decarbonisation solutions are applied.
Our Decarbonisation Sectors
Rail.
Leading the world in rollingstock decarbonisation
Battery Electric Locomotive
Medha collaborates to build new Battery Electric Locomotives (BELs), and is a pioneer in conversion of legacy Diesel locomotives with either DC or AC traction motors to Battery electric. Medha has BEL solutions for applications such as small industrial locomotives, shunters, intermodal, and heavy haul.
Hydrogen Electric Locomotive
Hydrogen Fuel Cell locomotives (HELs) uses fuel cells supplemented by battery to power its traction motors to propel the train. Medha designs and builds Hydrogen locomotive and is currently building Hydrogen locomotives inhouse that is slated for trials shortly.
Battery Electric Multiple Unit
Battery Electric Multiple Units (BEMUs) are self-propelled train sets that use electricity from onboard battery storage. They consist of multiple carriages, multiple of them with its own traction motors. Medha's BEMU solution can be interspersed with DEMU carriages to enable opportunistic switching between Diesel and Battery to reduce pollution in urban regions.
E-Tender Car
Medha designs and manufactures E-Tender car solutions to supplement existing Diesel locomotives with electric power. The electric power source can be either from overhead catenary or onboard battery storage. This solution can be used in routes with intermittent electrification or where external shore charging is available.
ZEBHRA(™) Traction Converters
ZEBHRA(™) is Medha’s modern efficient traction converter for Zero emission application. ZEBHRA is a combo converter with Generator Power Converter, Motor Power Converter, Traction Battery Buck-Boost Converter, Auxiliary Power Inverter, 24V DC Battery Charger, Drive Control Unit, and Dynamic Braking and Voltage Limit Unit, all in one cabinet.
Traction Battery Storage
Traction batteries are high capacity energy storage systems (ESS) to power locomotives or train consists. Medha designs, manufactures and supplies Battery Packs, Battery Management Systems (BMS) and Battery Thermal Management Systems (BTMS) for rail, road, marine and special vehicle applications.
Road.
Medha focuses exclusively on zero-emission vehicles in the road transport sector. Our expertise in zero-emission road vehicles dates back over a decade to electric trolley buses in Eastern Europe. To date, electric-powered buses equipped with our devices have travelled over 50 million kilometres.
Medha collaborates with OEMs to customize complete power train, control system and energy storage systems, and its integration. We also perform zero-emission conversions.
Explore our offerings by applications below.
Battery Electric Bus
Medha offers our customers complete battery electric kit and storage for Battery Electric Buses. Medha’s electric drives recuperate the energy generated during vehicle braking. The recovered energy is used to charge the batteries, which increases the range of the vehicle. The operation of the electric drive is not accompanied by vibrations or noise which significantly increases the comfort of travel.
Hydrogen Bus
Medha offers our customers complete hydrogen powertrain kit and onboard battery storage. We design, manufacture and integrate power electronic devices enabling the proper operation of the entire vehicle, particularly the hydrogen cell. Our latest Hydrogen bus commenced its passenger service in Gdansk, Poland in May 2024 with a range of 450 km on a single tank with refuelling taking just 15 minutes.
Trucks
Medha’s EV and battery storage kit are used in road trucks with gross vehicle weight up to 35 t currently. Our kit is mated with the vehicle shell to form the complete offering. Medha's suite of electric power train kit are used by globally reputed OEMs and adopted globally and meets all the safety standards. We customize the power train and gearbox to meet bespoke torque and power delivery requirements for each customer.
Construction Vehicles
Medha’s EV and storage kit are used in construction vehicles such as concrete mixers. Based on custom requirements, Medha can tailor solutions for special applications. Customization usually begins with understanding the operational cycle of the vehicle and its energy consumption, and subsequently sizing the power train and the selecting the appropriate battery chemistry and size.
Light Commercial Vehicles
Medha designs and supplies turnkey powertrain and battery electric kit for renowned LCV manufacturers across the world. LCV's that Medha specialises weigh typically up to 3.5 t and are designed for easy manoeuvrability and efficiency in urban traffic. They are versatile and used for variety of purposes and feature spacious cargo areas, making them ideal for transporting goods.
Mining.
Airport Vehicles.
Airport vehicles are specialised vehicles used for support activities on ground at an airport such as moving passengers between terminals and aircraft parked in the tarmac, and to move aircraft on the ground. Their unique features are quick charging capability and high torque requirement to handle the significant weight of aircraft. Medha focuses exclusively on zero-emission ground vehicles.
Tarmac Buses
13.5 m long low floor electric bus, 22 hrs operational cycle a day, LTO quick charging.
Aircraft Tugs
Electrified tugs with towing capacity up to 195 t, LTO quick charging
Marine.
Medha’s suite of offering for the marine space takes its roots from its foundational expertise in high torque, high power, and high energy efficient electric propulsion suite. We design and manufacture custom propulsion systems currently ranging up to 4.5 MW for use in large marine and submarine applications.
Renewables.
Medha offers a comprehensive suite of inverter and battery energy storage systems. Our focus is on empowering the generation, transmission, and distribution of solar power, along with seamless integration of both centralized and distributed energy storage systems (BESS).
