Abstract

The invention relates to a smart battery applicable to parallel connection and a parallel operation method of multiple smart batteries, which belongs to the technical field of smart batteries and solves a problem that multiple batteries cannot be directly connected in parallel for use in the prior art. The smart battery applicable to parallel connection comprises an electric core, a control unit,a charging and discharging unit, a charging and discharging interface and a current sensor, wherein the electric core, the charging and discharging unit and the charging and discharging interface aresequentially connected; the charging and discharging interface is used for connecting a charging device or electrical equipment so as to form a circuit; the current sensor is used for detecting the current of the circuit in real time; when the current I of the circuit is detected to be less than or equal to Ichg in the process of charging the electric core through the charging and discharging unit, the control unit controls the charging and discharging unit to switch to a state incapable of charging the electric core and clears a timer T; Ichg is the maximum charging current under the unauthorized state; and the smart battery is positive when being discharged and is negative when being charged. The smart battery provided by the invention can realize parallel connection of multiple batteries having unknown difference, and can meet differentiated requirements 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...
