Problems solved by technology

[0003] The purpose of the present invention is to provide a constant voltage battery energy management module device, which solves the problem in the prior art that the battery voltage drops after a period of use of the instrument battery, which cannot meet the production needs, and the remaining power of the battery cannot be used. Moreover, the voltage is unstable and cannot meet the requirements of the instrument; and most of the batteries in the prior art do not have a waterproof module, and cannot be installed in a large-scale instrument in Sihua, resulting in limited use and other problems.

Abstract

The invention discloses a constant-voltage battery energy management module device. The constant-voltage battery energy management module device includes an outer shell, an outgoing line plug and an incoming line plug are installed on the outer shell, and a circuit board is installed in the outer shell. It is equipped with a battery energy management module and a peripheral circuit module, which can solve the problem in the prior art that the battery voltage drops after a period of use of the meter battery, which cannot meet the production needs, and the remaining power of the battery cannot be used, resulting in voltage Unstable, unable to meet the requirements of the instrument; and most of the batteries in the prior art do not have a waterproof module, and cannot be installed in a wide range of Sihua instruments, resulting in problems such as limited use. Its miniature waterproof module can be installed in all Sihua instruments It is inside the battery and does not affect the use of the battery; it can maximize the remaining power of the battery and stabilize the voltage to meet the power requirements of the instrument.

Description

technical field [0001] The invention relates to the field of battery technology, and relates to a battery energy management module, in particular to a constant voltage battery energy management module device. Background technique [0002] At present, the instruments used in the process of promoting four-modernization production in the oil field mostly need to use lithium batteries such as ER34615, but the batteries cannot be charged, and the battery voltage will drop after a period of use, which cannot meet the production needs. The remaining power of the battery cannot be used, and the voltage is unstable, which cannot meet the requirements of the meter; and most of the batteries in the prior art do not have a waterproof module, and cannot be installed in a large-scale meter, resulting in limited use. Contents of the invention [0003] The purpose of the present invention is to provide a constant voltage battery energy management module device, which solves the problem in...
