Electric vehicle smoke alarm detection system and electric vehicle

Abstract

The invention discloses an electric vehicle smoke alarm detection system and an electric vehicle, and the system comprises a smoke alarm unit which is used for detecting the smoke concentration of the electric vehicle, and controlling an alarm part of the smoke alarm unit to give a smoke alarm when the smoke concentration exceeds a first preset concentration limit value; the control and communication unit is used for acquiring the smoke concentration, generating early warning prompt information when the smoke concentration exceeds a second preset concentration limit value, and sending the early warning prompt information to an external terminal for early warning prompt; the second preset concentration limit value is smaller than the first preset concentration limit value; the power supply unit comprises an electric vehicle power battery and a standby battery; when the power battery of the electric vehicle is normal, the power supply switching unit switches the power battery to supply power to the smoke alarm unit and the control and communication unit; when the power battery is abnormal or is charged, the power supply switching unit switches the standby battery to supply power to the smoke alarm unit and the control and communication unit, so that the use stability and safety of the electric vehicle are improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electric vehicles, and in particular, to an electric vehicle smoke alarm detection system and an electric vehicle. Background technique [0002] With the continuous upgrading of electric two-wheelers, the degree of intelligence is getting higher and higher. Intelligence is mainly reflected in the safety system, energy system, and central control system. How to better improve the performance and safety of the whole vehicle is the development of intelligence. the trend of. [0003] The aging of electronic circuits inside the vehicle or the failure of circuit components will have a significant impact on the vehicle and personal safety. When the circuits and components are not completely damaged, although a small amount of smoke may be generated, due to the low smoke concentration, users are often unable to pass through. Smell detection requires detection by a smoke alarm. In addit...

[0003] The aging of electronic circuits inside the vehicle or the failure of circuit components will have a major impact on vehicle and personal safety. When the circuits and components are not completely damaged, although a small amount of smoke may be generated, due to the low smoke concentration, users are often unable to pass. Smell detection, which needs to be detected by a smoke alarm

In addition, in emergency situations of electric vehicles (such as high-voltage power battery failure, battery short-circuit fire, charger fire caused by vehicle spontaneous combustion, electric vehicle internal device short-circuit failure caused by spontaneous combustion), it is impossible to give emergency warning in the first place, reducing The stability and safety of the vehicle
