The Importance of Temperature Sensors in CCS2 Charging Inlets

The electric vehicle (EV) industry is advancing at a rapid pace, driven by the increasing demand for sustainable and efficient transportation solutions. One of the critical components ensuring the safety and efficiency of EV charging is the Combined Charging System (CCS) connector. Among its various features, the temperature sensor plays a vital role in maintaining the operational integrity and safety of the charging process. This article will explore the significance of temperature sensors in CCS2 charging inlets and highlight the model options offered by Shenzhen Guchen Electronic Co., Ltd.
 

The Role of Temperature Sensors in CCS2 Charging Inlets

1. Safety Assurance: The primary function of a temperature sensor in a CCS2 charging inlet is to ensure the safety of the charging process. During high-power charging, connectors and cables can generate significant heat due to the electrical resistance and high current flow. Excessive heat can lead to dangerous situations such as thermal runaway, fires, or damage to the vehicle's battery and electronic systems. Temperature sensors monitor the temperature in real-time and can trigger safety mechanisms if the temperature exceeds safe limits, thus preventing potential hazards.
2. Enhancing Charging Efficiency: Temperature sensors also play a crucial role in optimizing the charging process. By monitoring the temperature, the charging system can adjust the charging current to maintain an optimal temperature range. This dynamic adjustment helps in maximizing the charging efficiency while minimizing energy losses due to excessive heat. Efficient temperature management ensures that the battery receives the appropriate amount of energy without being subjected to thermal stress.
3. Prolonging Component Lifespan: Consistent temperature monitoring and management help in extending the lifespan of the charging components and the vehicle's battery. High temperatures can accelerate the degradation of materials and electronic components, leading to premature failures. By keeping the temperature within safe limits, temperature sensors help in preserving the integrity of the charging infrastructure and the vehicle's battery, resulting in longer service life and reduced maintenance costs.
   

Guchen Electronic's Temperature Sensor Model Options

Shenzhen Guchen Electronic Co., Ltd. offers two temperature sensor model options for their CCS2 charging sockets:

1. PT1000 (Default Configuration):

• Rated Current: ≤0.3mA
• Insulation Resistance: ≥100MΩ（100V DC）
• Withstand Voltage: 3000V AC (60s)
• Flammability Rating: UL94 V-0

The PT1000 is a platinum resistance temperature sensor known for its high accuracy and stability. It is widely used in various industrial applications, including EV charging systems. The PT1000 sensor's low rated current ensures minimal power consumption, and its high insulation resistance and withstand voltage capabilities provide robust protection against electrical faults. The UL94 V-0 flammability rating ensures that the sensor meets stringent fire safety standards.
 

2. NTC (Available Option):

• Rated Current: ≤2mA
• Insulation Resistance: ≥100MΩ（100V DC）
• Withstand Voltage: 3000V AC (60s)
• Flammability Rating: UL94 V-0

The NTC 10K is a negative temperature coefficient thermistor, which offers a cost-effective solution for temperature sensing. It provides accurate temperature measurements with a quick response time, making it suitable for real-time monitoring in EV charging applications. Like the PT1000, the NTC 10K sensor also features high insulation resistance, robust voltage withstand capability, and a UL94 V-0 flammability rating, ensuring reliable and safe operation.

Temperature sensors are indispensable components in CCS2 connectors, playing a crucial role in ensuring safety, enhancing charging efficiency, prolonging component lifespan, and complying with regulatory standards. By integrating these advanced temperature sensors into their CCS2 charging sockets, Guchen Electronic continues to contribute to the development of safe, efficient, and reliable EV charging solutions.
