The temperature detection function of charge control chip is introduced
The temperature detection function of the charge control chip is a key part of ensuring the safety and efficiency of charging. The following is an introduction to the temperature detection function:
Main component
Purpose and function
The main purpose of the temperature sensor is to monitor the temperature of the charging pile itself and the electric vehicle battery, keep the temperature of the charging pile and battery within a safe range, and provide the necessary information to determine the charging power and the control strategy of the charging process.
Temperature sensor type
The commonly used temperature sensors of charging piles include Thermocouple, Thermistor, infrared temperature sensor, etc. Choosing the right sensor depends on the application requirements and performance requirements.
Installation position
The temperature sensor can be installed in the key parts of the charging pile, such as the charging power supply, charging line, battery connector, etc., to monitor the temperature of these components in real time. In addition, sensors can also be installed on the electric vehicle battery to monitor the temperature of the battery in real time.
Data acquisition and processing
The temperature sensor is connected with the control system of the charging pile, and the temperature data is transmitted to the control system for real-time acquisition and processing. The control system can calculate the algorithm according to the temperature data, and decide the charging power adjustment, temperature alarm or automatic stop charging measures.
Temperature Management strategy
Based on the data of the temperature sensor, the charging pile can implement temperature management strategies, such as dynamically adjusting the charging power, reducing the charging speed or stopping the charging when the temperature rises. These strategies help protect charging posts and batteries, extend their service life, and ensure the safety and reliability of the charging process.
Safety protection
The charging IC will monitor the temperature of the battery to prevent overheating. When the battery temperature exceeds the safe range, the charging IC will take appropriate measures, such as reducing the charging current or interrupting the charging process, to protect the battery safety
Characteristics
The temperature sensing principle of digital temperature sensor is based on the characteristic relationship between CMOS semiconductor PN section temperature and band gap voltage, after small signal amplification, analog-to-digital conversion, digital calibration compensation, through the digital bus output. The sensor has the advantages of high precision, low power consumption, good consistency, fast temperature measurement, flexible programmable configuration and long service life.
Through these functions, the temperature detection of the charging control chip can provide a comprehensive safety protection for the charging pile, ensure that the charging process is carried out within a safe temperature range, and prevent equipment damage or safety accidents caused by temperature anomalies.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
