Electric Vehicle Thermal Management
Apr 26 , 2023
Thermal management has been an issue for as long as there have been engine-driven vehicles - because the temperature of the engine and surrounding components can affect the performance and safety of the vehicle. Beyond normal thermal thresholds, the consequences of poor thermal management can be as inconvenient as overheating, or even as devastating as a fire. Electric vehicle thermal management i...

EV sensor technology extends, optimizes battery life
Apr 27 , 2023
Sensor technology throughout the battery pack is key to maintaining the battery in the short and long term. Sensor technology allows the thermal management system in an EV to start working as soon as it registers a temperature outside of the comfort zone range. Temperatures that are too hot or too cold can have a similar effect on EV batteries and their health. Excessive temperatures can affe...

Fluid Sensors for EV Thermal Management
Apr 27 , 2023
On a macro level, thermal management of EV batteries goes beyond temperature sensors. When monitoring the health of an EV battery, leak detection is essential, whether the vehicle is charging or on the road. Leaks of any kind can directly affect the battery or the system that keeps its temperature in the right range for optimal performance. 1、Liquid coolant Instead of circulating throu...

Development of temperature sensors
May 26 , 2023
The perception of heat and cold is fundamental to the human experience, yet figuring out how to measure temperature has eluded many great men. It is unclear whether it was the ancient Greeks or the Chinese who first found a way to measure temperature, but it is well documented that the history of temperature sensors began in the Renaissance. We started with the challenges of temperature measuremen...

Basic concept of thermistor
Jun 29 , 2023
Basic concept of thermistor Thermistors are a class of sensitive elements whose resistance value varies with temperature. Depending on the temperature coefficient, thermistors can be divided into two types: positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC). Positive temperature coefficient thermistors (PTC) increase in resistance when th...

How PTC Thermistors Work
Jun 29 , 2023
How Thermistors Work The thermistor will not operate for a long time; when the ambient temperature and current are in zone c, the heat dissipation power of the thermistor is close to the heat generation power, so the thermistor may or may not operate. When the thermistor is in the same ambient temperature, the action time is sharply shortened with the increase of current; the thermistor has a shor...

Thermal Energy Storage and Sensors
Jul 28 , 2023
Storing thermal energy in tanks or underground facilities saves excess energy for later use - days, hours or even months. Thus, the concept of Thermal Energy Storage (TES) bridges the gap between energy supply and energy demand. By 2050, world energy consumption is expected to increase by 50 per cent. At the same time, the world's traditional energy resources are being depleted. In order to adapt ...
