Combined general type power management balancer applied to multiple batteries and working method thereof

Abstract

The invention discloses a combined general type power management balancer applied to multiple batteries and a working method thereof. The combined general type power management balancer applied to multiple batteries is mainly composed of a working power supply output module, a charging module, the batteries, a power / function switching module, a reverse charging prevention circuit module, a power module, an undervoltage reference value module, a CPU, a working voltage sampling module, a driving module and an undervoltage indication alarm module. According to the combined general type power management balancer applied to the multiple batteries, single batteries are connected in series and combined with undervoltage protection added to output voltages for supplying power, the batteries are connected in parallel according to groups to be charged and work, and the power / function switching module, the reverse charging prevention circuit module, the undervoltage reference value module, the driving module and the undervoltage indication alarm module are arranged, and products are made to have the advantages of being high in safety, low in usage cost, good in stability and long in service life.

Description

technical field [0001] The invention relates to a general-purpose power management equalizer suitable for a combination of multiple batteries and a working method thereof. Background technique [0002] In fact, the history of electric vehicles is earlier than our most common internal combustion engine-driven vehicles. The father of the DC motor, the Hungarian inventor and engineer Anyusjedlik, first tested the electromagnetic rotating action device in the laboratory in 1828. American Thomas Davenport produced the first electric car driven by a DC motor in 1834. From 1860 to 1920, with the development of storage battery technology, electric vehicles also achieved technical development. At the end of the 19th century, electric vehicles were odorless, vibration-free, noise-free, without shifting gears, and low in price. sales of electric vehicles in 2019 exceeded sales of vehicles powered by internal combustion engines. Today, the popularity of electric vehicles has far exce...

Problems solved by technology

Because the material, manufacturing process and usage conditions of the battery determine the difference in the performance of a single battery, so charging and discharging in series will cause overcharging, undercharging and overdischarging between single batteries, not only the safety performance is too low, It also accelerates the aging and damage of the battery during use. If it cannot be repaired or replaced in time, it will accelerate the damage of the entire set of batteries. While reducing the service life, the stability of the battery cannot be guaranteed, which in turn increases the cost of use and maintenance. cost, increasing the difficulty of battery matching
