Abstract

The invention relates to an intelligent battery suitable for parallel connection and a parallel working method for multiple intelligent batteries, which belongs to the technical field of intelligent batteries and solves the problem in the prior art that multiple batteries cannot be directly used in parallel. An intelligent battery suitable for parallel connection, including a battery cell, a control unit, a charging and discharging unit, a charging and discharging interface, and a current sensor; the battery core, the charging and discharging unit, and the charging and discharging interface are connected in sequence; the charging and discharging interface is used to connect the charging The device or electrical equipment forms a loop; the current sensor is used to detect the loop current in real time; when the loop current I≤I is detected during the charging process of the battery through the charging and discharging unit chg , the control unit controls the charging and discharging unit to switch to the state where the battery cannot be charged, and clears the timer T; I chg It is the maximum charging current in the unauthorized state; the intelligent battery discharge is positive, and the charging is negative. The intelligent battery provided in the present invention can realize the parallel connection among multiple batteries with unknown differences, and can meet the differentiated demands of different users.

Description

technical field [0001] The invention relates to the technical field of smart batteries, in particular to a parallel working method suitable for parallel connected smart batteries and multiple smart batteries. Background technique [0002] In some electrical equipment, especially electric bicycles, a large number of parallel / series batteries are used. Different users have different requirements for the capacity, volume, and weight of batteries. Some users expect high capacity and long battery life, and some users expect the battery to be light and easy to replace. To meet the differentiated needs of different users, previous solutions provided batteries with different capacities for different users. This has resulted in a wide variety of battery models with inconsistent capacities and sizes. [0003] For the service mode of providing shared power batteries, if batteries with different capacities are provided according to different needs of users, it will increase the compl...
