The invention discloses a multi-point temperature control protection device for a lithium ion power battery. Specifically, the invention relates to the field of batteries. The device comprises a protective shell. A battery body is arranged in the protective shell. A plurality of groups of adjusting grooves are formed in the top and the bottom of the protective shell in a penetrating manner. A telescopic rod is arranged in the adjusting groove in a sliding manner. A temperature control detector is fixedly installed at the end, located in the protective shell, of the telescopic rod. And a magnetic block is arranged at the end, away from the telescopic rod, of the temperature control detector, a thread is formed in the rod wall of the end, located in the adjusting groove, of the telescopic rod, a fixing nut is arranged outside the rod wall of the telescopic rod in a sleeving mode, the fixing nut is in threaded connection with the telescopic rod, and one side of the protective shell is sleeved with a box cover. According to the invention, the plurality of groups of temperature control detectors are arranged to control the communication of the heat dissipation loop, and the heat dissipation fan pumps out hot air in the protection shell, so that the temperature of the battery body can be reduced to achieve the effect of protecting the battery.
Description
technical field [0001] The invention relates to the technical field of batteries, and more specifically, the invention relates to a multi-point temperature control and protection device for a lithium-ion power battery. 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 advantages of 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. [0003] There are some disadvantages in the existing lithium-ion power battery, that is, the battery will heat up after a period of time of power supply or charging, which will cause the temperature of the battery to rise...
