Intelligent cell terminal, intelligent power supply terminal and matched detection method

Abstract

The invention provides an intelligent cell terminal, an intelligent power supply terminal and a matched detection method. A cell module and a cell management system are arranged in a cell. A main power supply loop, a pre-discharging branch and a communication port I are arranged on the cell. The pre-discharging branch is connected with the cell module. The communication port is connected with the cell management system. By adding the pre-discharging branch and the communication port on / in the intelligent cell module on the basis of a common cell module, it is adopted by acquiescence that limit current is output through the pre-discharging branch, so the cell can be prevented from being damaged caused by mis-short circuit in a settling or moving process. Through the communication port, it is ensured that normal power supplying (information encryption transmission) is performed only after information interaction succeeds between the cell terminal and an electricity utilization system, or else, the electricity utilization system cannot work normally, so use of a fake cell on a product is avoided.

Description

technical field [0001] The invention relates to the design field of a battery management system of a lithium battery module, and the application occasions include electric bicycles, scooters, balance cars, twisters, unmanned aerial vehicles, robots and other products that use lithium batteries to provide energy. Background technique [0002] With the popularization of lithium batteries, more and more products start to use lithium batteries to provide power source for products, but currently many products use lithium batteries without battery management system, or the protection function of the battery management system is not enough. Perfect, this type of battery is prone to the following problems during use: [0003] 1. The battery voltage is directly output to the outside. Touching the port can easily trigger the short-circuit protection of the battery. In the case of a high voltage level, it will cause harm to the human body. [0004] 2. The interface design is simple an...
