Energy storage sensor field spatial analysis

What types of sensors are used in energy storage devices?

Section 4 summarizes the characteristics of existing sensors used in new energy storage devices, and predicts future research and an improvement direction from the perspective of actual working conditions. Non-embedded sensors mainly include current, voltage, temperature, and strain sensors, as well as several types combined with optical sensors.

What are the key parameters of energy storage devices?

In this paper, the measurement of key parameters such as current, voltage, temperature, and strain, all of which are closely related to the states of various new energy storage devices, and their relationship with the states of those devices are summarized and explained, mainly for non-embedded sensors and embedded sensors.

What are the different sensing methods used in energy storage devices?

These are highly related to their states. Hence, this paper reviews the sensing methods and divides them into two categories: embedded and non-embedded sensors. A variety of measurement methods used to measure the above parameters of various new energy storage devices such as batteries and supercapacitors are systematically summarized.

Can thermal resistance sensors be used as embedded sensors?

Thermal resistance sensors can be subdivided into thermistors and RTDs. However, because of the incompatibility of the size of the sensors and the design of the energy storage device, they are rarely used as embedded sensors so as to avoid affecting the performance and long-term cycle life.

Can FBG sensor solve a spatially uneven temperature distribution problem?

The experimental results showed that the FBG sensor has a faster response speed and higher sensitivity, and can solve the problem of not obtaining spatially uneven temperature distribution in single point measurement.
