Description

Technical Field

[0001] The utility model belongs to the technical field of new energy batteries, and in particular relates to an anti-collision type new energy battery. Background Art

[0002] At present, the three common types of batteries for new energy vehicles are: ternary lithium batteries, lithium iron phosphate batteries and nickel-metal hydride batteries. Among them, ternary lithium batteries and lithium iron phosphate batteries have higher energy density and more stable performance. These two types of batteries are the most widely used in electric vehicles. Nickel-metal hydride batteries are also a type of battery with good performance and are gradually being used in the field of new energy vehicles.

[0003] Existing new energy batteries are generally installed in battery boxes. During the driving of new energy vehicles, some uncontrollable accidents often occur, causing the vehicles to collide. However, the protection performance of the battery box is poor. When a more serious collision occurs, the battery box is prone to deformation and squeeze the battery. In severe cases, the battery may catch fire, causing great harm and property losses. In order to solve the above problems, an anti-collision new energy battery is proposed. Utility Model Content
