The present invention relates to a low-rise street tram equipped with a vehicle battery, and more particularly, by lowering the height of the vehicle floor to provide excellent accessibility for passengers and providing high-quality services to transportation vulnerable people such as stroller users and the elderly. The present invention relates to a low-rise streetcar that can run without installing a wire, thereby improving aesthetics of a city and equipped with a safe vehicle battery.

In general, a streetcar or tram, tram, tramcar, trolley, or streetcar is one of the means of transportation, and is generally referred to as an electric vehicle moving along a rail laid on a road.

In the early stage of the tram was a high-rise vehicle with a vehicle floor of about 1.2m high, but in recent years, a low-rise tram with a lowered vehicle floor is being operated to improve convenience for people with disabilities, strollers, and the elderly.

In addition, the development of a streetcar that was driven by using the charged electric energy of the secondary battery mounted in the vehicle without the supply of electricity through the wire in the streetcar that was previously operated only by the supply of electricity through the wire.

Such low-rise streetcars have a height of about 300mm from the bottom of the body to the ground, so the space on the bottom of the vehicle is so narrow that only the vehicle, which is essential for driving the tank, is provided at the bottom of the vehicle. It consists of a structure mainly mounted on the roof.

On the other hand, the technology up to now has a large capacity secondary battery capable of generating a propulsion energy capable of traveling several tens of kilometers without wires is bulky and heavy, taking up a lot of space.
