M42 Battery
The M42 is a modern power battery represented by lithium-ion batteries, with a nominal voltage of 3.66 V and a capacity of 15 Ah. The energy density is 128 Wh / kg. The efficient conversion of electrical energy and chemical energy is achieved through the redox reaction of positive and negative electrode materials. Its modular design allows flexible combination according to different application scenarios, from the energy supply of electric vehicles with a range of 100 kilometers to the megawatt-level power regulation of energy storage power stations, all of which can operate stably with excellent charging and discharging efficiency and safety performance. The built-in battery management system (BMS) is like an intelligent housekeeper, monitoring voltage, temperature and charging and discharging status in real time, extending battery life through balancing technology, and cooperating with the thermal management system to ensure performance in extreme environments.
As a subsidiary of EMAC, EVMac provides electric drive axles, drive motors, power batteries, and vehicle controllers. As the electrification of automobiles becomes an inevitable trend, EVmac has also entered the field of electric vehicle powertrain systems.
We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.
Advantages of M42 Power Battery

Power batteries serve as the energy cornerstone in the new energy field. As the core units for energy storage and supply, they enable the efficient storage and release of electrical energy through reversible electrochemical reactions. Take the mainstream lithium – ion batteries as an example. The CRRC Zhuzhou 1435 series dual rail sightseeing car inherits the technological DNA of CRRC high-speed rail and is designed for in-depth sightseeing in scenic areas. The innovative double-decker structure features a panoramic window on the first floor for comfortable all-weather sightseeing and an open-top layout on the second floor for a 360° immersive natural experience. CHSR's CHSR™ CC750 air-cooled converter is a highly integrated traction and auxiliary "two-in-one" core equipment. It condenses key power conversion functions into a single compact enclosure, providing robust and stable power for intercity trains through standardized modular design, intelligent air cooling (IP65 protection), and mature and reliable components. CRRC Braking Systems Co., Ltd.'s disc brake calipers use hydraulic or pneumatic-hydraulic conversion drive technology.They integrate automatic gap adjustment, modular caliper body, and three-point floating suspension design to ensure precise contact between brake pads and discs. RailMac provides railway solutions, focusing on one-stop Lince/Huanji wiper services (R&D, production, maintenance) plus rail air conditioning. It offers diverse wipers (DC110V/74V/24V, pneumatic) and developed China’s first IP-owned CRH3 EMU wiper, with products batch-loaded in CRH380/CR400BF/CR300BF. RunWell is a high-tech enterprise specializing in the fields of rail transit and military industry. Its car lift machine products integrate German drive technology (such as the Demag three-in-one modular system) with intelligent control, supporting heavy-duty conditions of over 150 tons. CRRC specializes in innovative environmental protection sanitation systems. Products like vacuum water - saving toilet modules and waterless ecological toilets, made in an orderly factory, are applied in railways, public facilities, and outdoor scenarios. Partnering with global leaders, RailMac offers superior railway equipment and solutions at competitive prices. It hit milestones like Thailand’s 2017 first local train, pioneered SEA new energy trains, and joined Russia’s high-speed rail project, boosting its railway industry presence.Power Battery
