Embodiment

[0038] like figure 1 As shown, a battery pack protection system based on voice control includes: battery pack, charging and discharging equipment, positive relay, negative relay, voice input module, voice recognition module, control module and relay drive module. The battery pack is connected to the charging and discharging device through a positive power line and a negative power line, the positive relay is connected in series in the positive power line, and the negative relay is connected in series in the negative power line. In actual application, the positive relay and the negative relay can be integrated with the battery pack, or can be integrated with the charging and discharging equipment.

[0039] In this embodiment, the voice input module is a microphone. The speech recognition module adopts LD3320 chip. The LD3320 chip is a "speech recognition" dedicated chip. LD3320 chip integrates speech recognition processor and some external circuits, such as AD, DA converter,...

Abstract

The invention relates to a battery pack protection system and method based on speech control. The system comprises a battery pack, a charge-discharge device, a relay, a speech input module, a speech recognition module, a control module and a relay drive module, wherein the charge-discharge device is connected with the battery pack through a power line, the relay is connected to the power line in series, the speech input module is used for collecting speech signals and transmitting the speech signals to the speech recognition module, the speech recognition module compares the speech signals with prestored action phrases in a phrase list and sending the action phrases the same as the speech signals to the control module, the control module outputs corresponding action control instructions to the relay drive module according to the action phrases of the speech recognition module, and the relay drive module controls the relay to make corresponding actions according to the action control instructions of the control module. The battery pack and the charge-discharge device can be disconnected through speech instructions, short-distance operation is needless, the security is greatly improved, and speech control is more convenient.

Description

technical field [0001] The invention relates to the technical field of battery pack safety, in particular to a battery pack protection system and method based on voice control. Background technique [0002] Nowadays, electric vehicles are developing rapidly. In response to Industrial Manufacturing 4.0, China has proposed the concept and development direction of "Made in China 2025". Intelligence will dominate the future direction of industrial development and bring about major changes and impacts on people's lives. The safety of electric vehicles has always been the focus of most attention. [0003] The existing battery management system can only deal with the internal faults of the battery pack, such as single cell disconnection, short circuit, overcurrent and other abnormal conditions, but cannot quickly deal with some problems in the external environment. For example, in the prior art, when a fire occurs around the charging station or an abnormality occurs in the chargi...
