Problems solved by technology

[0002] When the lithium battery pack is transported or left standing for a long time, the battery management system (hereinafter referred to as BMS) or the protection board will have a weak power consumption. Because the battery pack can only be charged to 30% of its capacity for safe transportation when it leaves the factory, so long-term Without charging, these weak power consumption will cause the battery to be over-discharged, resulting in failure to use normally

Abstract

The invention relates to a low-power-consumption battery management system, which comprises a microprocessor U1, and a power supply module, a vibration controllable circuit unit, a voltage acquisition module, a storage module, a current detection resistor and a communication module which are connected with the microprocessor U1, wherein the communication module is connected with a PC or handheld equipment in a wireless manner. By additionally arranging the low-power-consumption vibration controllable circuit unit on a BMS or a battery protection board, and combining with a specially designed circuit and special configuration equipment, the low-power-consumption battery management system realizes low power consumption in battery standing and long-distance transport, can reduce the power consumption of the battery management system or the protection board to extremely low when a battery pack is not in use, ensures that excess electric quantity of the battery pack is not consumed in the long-term standing or transport process, and does not affect the normal use of the battery pack.

Description

technical field [0001] The invention belongs to the field of lithium batteries and relates to management of lithium batteries, in particular to a battery management system with low power consumption. Background technique [0002] When the lithium battery pack is transported or left standing for a long time, the battery management system (hereinafter referred to as BMS) or the protection board will have a weak power consumption. Because the battery pack can only be charged to 30% of its capacity for safe transportation when it leaves the factory, so long-term Without charging, these weak power consumption will cause the battery to be over-discharged, resulting in failure to use normally. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a battery management system with low power consumption to ensure that the power of the battery pack is not excessively consumed during long-term standing or ...
