What is a liquid level sensor

What is a liquid level sensor

Liquid level sensor (hydrostatic level gauge/liquid level transmitter/liquid level sensor/water level sensor) is a pressure sensor that measures liquid level. The static pressure input liquid level transmitter (liquid level gauge) is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffusion silicon sensitive element or a ceramic capacitive pressure sensitive sensor to convert the static pressure into The electrical signal is converted into a standard electrical signal (usually 4～20mA/1～5VDC) through temperature compensation and linear correction, which is suitable for various systems and industries such as petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and so on. Level measurement of media.

When the temperature is low, what will happen to the battery temperature control system of the new energy vehicle?

When the temperature is low, what will happen to the battery temperature control system of the new energy vehicle?

1. The charging speed is slow. Due to the low activity of lithium ions at low temperatures, the charging current will be limited in order to protect the battery vehicle, so the charging time will be slow.

Three temperature control technologies of battery pack thermal management system

Air cooling Air cooling is a heat dissipation method that uses low-temperature air as the medium to reduce the temperature of the battery by using heat convection. It is divided into natural cooling and forced cooling (using fans, etc.).

Analysis of the core technologies of the three major control systems involved in new energy vehicles

"The biggest change in the automotive industry is that it was dominated by hardware in the past, and it has become a software-led, effective integration of software and hardware." During the 2021 World New Energy Vehicle Conference, Dean of the Institute of Automotive Industry and Technology Strategy of Tsinghua University, World Auto Zhao Fuquan, life-long honorary chairman of the Federation of Engineers, believes that only the effective integration and development of software and hardware can make the function, performance, and especially the personalized experience of the car to the extreme.

What are the precautions for battery thermal runaway?

What are the precautions for battery thermal runaway?

The thermal runaway of the battery means that when the battery is charged at a constant voltage, the charging current and the temperature of the UPS battery have a cumulative enhancement effect, and the battery is gradually damaged. And it is difficult to dissipate heat, but with proper measures and careful maintenance, thermal runaway can be prevented.
