Embodiment 1

[0056] In order to solve existing technical problems, such as figure 1 As shown, the embodiment of the present invention provides a battery pack wake-up method, the method comprising:

[0057] S101. After receiving a high-level signal sent by the second BMS, the first BMS switches from a sleep state to a working state.

[0058] It should be noted that during the sleep state, many functional modules in the battery management system stop working, so they are in a state of power saving. When the battery management system needs to work normally, or when a specific functional module is working , it is necessary to wake up the battery management system.

[0059] It can be understood that the first BMS manages the first battery pack, the second BMS manages the second battery pack, and both the first BMS and the second BMS are independent battery pack management units. The first BMS includes a positive pole and a negative pole, and the second BMS includes a positive pole and a negat...

Embodiment 2

[0074] exist figure 1 On the basis of the illustrated embodiment, the embodiment of the present invention provides a method such as figure 2 In the illustrated embodiment, the method for waking up the battery pack includes the steps of:

[0075] S201. After receiving a high-level signal sent by the second BMS, the first BMS switches from a sleep state to a working state.

[0076] S202. Convert the high-level signal into an output-level signal.

[0077] S203. Send the output level signal to the second BMS, so that the second BMS switches from a dormant state to a working state.

[0078] It can be understood that steps S201 to S203 in the embodiment of the present invention are the same as steps S101 to S103, and the embodiment of the present invention will not repeat them here.

[0079] S204. Detect the electrical signal of the second BMS.

[0080] Those skilled in the art can understand that when the second BMS is in the working state, its various functional modules are a...

Embodiment 3

[0093] exist figure 1 On the basis of the illustrated embodiment, the embodiment of the present invention provides a method such as image 3 In the illustrated embodiment, after receiving the high-level signal sent by the second BMS, the step of converting the first BMS from the dormant state to the working state specifically includes:

[0094] S301. After receiving the high-level signal sent by the second BMS, the wake-up line generates a rising edge signal.

[0095] It can be understood that after the high-level signal sent by the second BMS passes through the wake-up line between the first BMS and the second BMS, the high-level signal on the wake-up line generates a corresponding rising edge signal.

[0096] Exemplarily, the high-level signal sent by the second BMS is 5V, and the wake-up line generates a rising edge signal with a rising edge of 5V, or a rising edge signal with a rising edge of 3.8V, and a rising edge signal with a rising edge of 4.5V Signals, etc., are no...

Abstract

The method is suitable for the technical field of battery pack management, and provides a battery pack awakening method and device, electric equipment and garden equipment; the battery pack awakeningmethod comprises the steps that after a high-level signal sent by a second BMS is received, a first BMS is converted into a working state from a dormant state; the high-level signal is converted intoan output level signal; and the output level signal is sent to the second BMS, so that the second BMS is converted into the working state from the dormant state. According to the embodiments of the invention, the battery pack can be charged by a battery pack without needing a pressing key or an external activation operation, so that the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of battery pack management, and in particular relates to a battery pack wake-up method, device, electric equipment and garden equipment. Background technique [0002] The battery pack is a battery that provides the core energy source for large and small equipment or devices, and is used to provide driving power. Generally speaking, the battery pack mainly constitutes the main body of the battery pack through the envelope of the shell. The main components include batteries, modules, and battery management systems. , Shell, etc. The battery management system (Battery Management System, referred to as BMS) is a system that manages the battery. It usually has the function of measuring the battery voltage to prevent or avoid abnormal conditions such as over-discharge, over-charge, and over-temperature of the battery, and to monitor the battery. The role of monitoring and management. Common applications include:...
