Abstract

The invention discloses an automatic temperature control device in a battery box. The automatic temperature control device comprises a battery box, a box cover and temperature control assemblies, wherein the box cover is mounted at the top end of the battery box, an automatic temperature controller is inlaid in the box cover, and a plurality of temperature sensors are mounted at the bottom of thebox cover; a battery is arranged in the battery box and formed by a plurality of longitudinal cell groups. The temperature control assemblies are mounted on two sides of the battery, a plurality of second heat conductive plates in the temperature control assemblies are just inserted between the cell groups pairwise, temperature of first heat conductive plates and the second heat conductive platescan be changed by semiconductor chilling plates, so that temperature of the battery is affected, and the temperature control effect is realized; the temperature control assemblies are controlled by the automatic temperature controller, an MCU (microprogrammed control unit) can change polarity of current input into the temperature control assemblies through an electrode change module according to temperature transmitted by the temperature sensors, and accordingly, cold-heat switch of the semiconductor chilling plates is realized. The automatic temperature control device has the characteristic of automatic temperature control of the battery.

Description

technical field [0001] The invention relates to an automatic temperature control device, in particular to an automatic temperature control device in a battery box, belonging to the technical field of electric vehicle batteries. Background technique [0002] In 1860, Plantai of France invented a battery using lead as an electrode. The unique feature of this battery is that it can be charged and used repeatedly, so it is called a "lead-acid battery". Therefore, the vast majority of current electric vehicles are equipped with lead-acid batteries, because lead-acid batteries are low in cost and cost-effective. At the same time, some electric vehicle batteries use lithium batteries. Electric vehicles are generally powered by batteries. There are many types of batteries, such as: nickel-cadmium rechargeable batteries, nickel-metal hydride rechargeable batteries, lithium rechargeable batteries, lead-acid batteries, solar batteries, Crystal gel batteries, lithium iron phosphate ba...
