Abstract

The invention discloses a multi-layer lithium ion power battery pack supporting device. The device comprises a battery pack, a battery fixing plate, a heat dissipation frame and a bottom fixing frame, the battery pack is arranged in the center over the battery fixing plate, the battery fixing plate is arranged in the center of the top of the heat dissipation frame, a mounting groove is formed in the top of the bottom fixing frame, the heat dissipation frame is integrally arranged in the mounting groove, buffer springs are arranged at the four corner ends of the bottom of the heat dissipation frame, an air guide cavity is formed in the bottom of the bottom fixing frame, a plurality of air guide holes are formed in the two sides of the upper surface of the bottom of the bottom fixing frame, and the tops of the air guide holes communicate with the interior of the mounting groove. The bottom ends of the air guide holes communicate with the interior of the air guide cavity, and an air outlet plate is arranged at the bottom of the bottom fixing frame. The multi-layer lithium ion power battery pack supporting device provided by the invention can effectively protect the overall safety of the battery pack, and the internal heat dissipation fan can provide an effective heat dissipation effect for the battery pack, so that the device is more practical.

Description

technical field [0001] The invention relates to the field of lithium-ion power batteries, in particular to a support device for a multi-layer lithium-ion power battery pack. Background technique [0002] Lithium-ion power battery is a new type of high-energy battery successfully developed in the 20th century. The negative electrode of this battery is made of materials such as graphite, and the positive electrode uses lithium iron phosphate, lithium cobaltate, lithium titanate, etc. It became practical in the 1970s. Because of its high energy, high battery voltage, wide operating temperature range, and long storage life, it has been widely used in military and civilian small electrical appliances. Lithium-ion power batteries are used in mobile phones, portable computers, video cameras, cameras, etc., partially replacing traditional battery. Large-capacity lithium-ion batteries have been tried in electric vehicles and will become one of the main power sources for electric v...
