[0003] For example, the prior art strictly detects the temperature of the lithium battery during charging and discharging, such as setting up a detection device that does not take protective measures when the surface temperature of the lithium battery does not rise to the threshold, but ignores the vibration of the lithium battery. However, when the roads of intelligent networked vehicles are relatively rough, when the vibration amplitude of the lithium battery is too large, it is very easy to cause a short circuit inside the lithium battery, start to emit heat, and cause the surface temperature to rise, but the detection device mistakenly detects this The phenomenon is considered to be a normal phenomenon of discharge heating and ignored, and there is no device for detecting lithium battery vibration in the prior art, which threatens the safety of intelligent networked vehicles

The invention discloses an intelligent networked automobile detection device, and effectively solves the problem that the safety of an intelligent networked automobile is threatened because a detection device in the prior art mistakenly considers the temperature rise phenomenon of a lithium battery caused by overlarge vibration amplitude of the lithium battery as a normal phenomenon of discharge temperature rise. The detection device comprises a vibration detection circuit, a temperature comparison circuit and a signal output circuit, the vibration detection circuit uses a vibration sensor U1 to detect a vibration signal of a lithium battery, the vibration signal passes through a receiver and a judger, then the temperature detection circuit is conducted, and meanwhile the vibration signal is transmitted to the signal output circuit; the temperature comparison circuit detects a temperature signal on the surface of a lithium battery through a thermistor PTCR, outputs a comparison result through an operational amplifier U2B, transmits the comparison result to the signal output circuit, and the signal output circuit generates an alarm signal to an ECU through a conduction device and an oscillator according to the comparison result and a vibration signal, so that people in a vehicle are reminded in time.
Description
technical field [0001] The invention relates to the field of intelligent networked vehicles, in particular to a detection device for intelligent networked vehicles. Background technique [0002] Intelligent networked vehicles are an organic combination of the Internet of Vehicles and smart vehicles. They are equipped with advanced control systems and combined with modern communication and network technologies to realize the exchange and sharing of intelligent information between vehicles and people, vehicles, roads, and backgrounds, and realize safety, comfort, and convenience. Energy saving and high-efficiency driving. In response to the call of the country for environmental protection, ICVs have gradually changed the power source from gasoline to lithium batteries, which reduces the pollution of vehicle exhaust to the environment. For the safety of ICVs , There are also many detection devices for lithium batteries. [0003] For example, the prior art strictly detects the ...
