The invention relates to a new energy rail car with a lithium iron phosphate power battery pack. The new energy rail car comprises a car body, a compartment, a walking part, a braking system, a traction transmission system and a battery pack. The battery pack adopts lithium iron phosphate power batteries, adopts modular design, and is arranged on two sides in the compartment, so that a gap betweenthe lower part of the rail car and a rail surface is increased, and the operation safety performance is improved; the compartment is provided with a skylight, and the battery module can be hoisted inand out of the compartment through the skylight, so that the time required for replacing, charging or overhauling the battery pack is greatly shortened, and the utilization rate of the new energy rail car is increased; and a cooling and heating all-in-one machine is adopted to ensure that the working temperature of the battery module is kept within a proper range, so the effective capacitance ofthe battery pack is improved, and the environment temperature application range of the battery pack is expanded. The new energy rail car with the lithium iron phosphate power battery pack is high in charging speed, large in capacity, long in service life, good in safety, good in high-temperature performance, long in endurance mileage and good in pavement adaptability and operation safety.
