Introduction

Temperature monitoring is an important part of lithium battery pack design.

During charging and discharging, battery temperature can change significantly. An NTC temperature sensor provides the BMS with real-time temperature feedback, helping the system monitor and control battery operating conditions.

Among different NTC sensor structures, Nickel Tab NTC Temperature Sensors are particularly suitable for applications where compact size, direct thermal contact and simple installation are important.

1. Compact Structure for Limited Installation Space

Battery packs usually have limited internal space.

A traditional stainless steel probe may require additional mounting space, while a nickel tab sensor can provide a much more compact sensing structure.

The flat metal tab can be designed to fit the battery assembly while keeping the sensing element and wiring relatively compact.

This makes the structure suitable for:

• Battery cells
  
• Battery modules
  
• Battery packs
  
• Energy storage systems
  

2. Direct Thermal Contact

The sensor's metal tab can make direct contact with the monitored surface.

This creates a relatively short thermal path between the battery surface and the NTC sensing element.

For battery temperature monitoring, good thermal contact is important because the sensor needs to detect temperature changes accurately and consistently.

The Xinshiheng Nickel Terminal NTC Temperature Sensor uses a pure nickel housing with a sensitive NTC thermistor chip.

3. Fast Response to Temperature Changes

Battery temperature may change during:

• Fast charging
  
• High-current discharge
  
• Continuous operation
  
• High ambient temperature
  
• Abnormal operating conditions
  

An NTC thermistor has high temperature sensitivity, while the compact tab structure helps provide efficient thermal transfer.

This combination makes it suitable for applications where the BMS needs timely temperature feedback.

The product is specifically designed for high sensitivity and fast temperature response.

4. Simple Surface Mounting

Another advantage of the nickel tab structure is installation.

Instead of inserting a probe into a mounting hole, a tab-type sensor can be designed for direct surface mounting.

This can simplify the mechanical structure of the battery pack and make assembly more convenient.

For high-volume battery production, a simple installation method can also help improve assembly efficiency.

Xinshiheng specifies this product as suitable for easy surface mounting and mass production.

5. Flexible Electrical Parameters

There is no single NTC specification suitable for every battery system.

Depending on the BMS design, customers may require different resistance values and B values.

The Xinshiheng Nickel Terminal NTC Temperature Sensor supports multiple R25 values, including 300Ω, 2.252KΩ, 4.7KΩ, 5KΩ, 10KΩ, 20KΩ, 50KΩ and 100KΩ, among others.

Available B-value options include 3187K, 3380K, 3435K, 3950K and 3977K, with additional customized specifications available.

6. Customized for Different Battery Designs

Battery manufacturers may have different requirements for sensor dimensions, wire routing and installation.

Therefore, mechanical customization can be just as important as electrical parameter selection.

Possible customization options include:

Electrical parameters

• R25 resistance
  
• B value
  
• Resistance tolerance
  
• Operating temperature range
  

Mechanical parameters

• Nickel tab dimensions
  
• Sensor dimensions
  
• Wire length
  
• Wire configuration
  
• Connector configuration
  

Xinshiheng's product specifications state that dimensions and lead length can be customized, while connector requirements can also be specified according to the application.

7. Suitable for Battery Temperature Monitoring

Nickel Tab NTC Sensors can be used in various battery-related applications, including:

Battery Cells → Battery Modules → Battery Packs → BMS

They can also be used for battery temperature measurement in new energy vehicles and other automotive temperature-monitoring systems.

How to Choose a Nickel Tab NTC Sensor?

When selecting a sensor for a battery application, we recommend confirming the following parameters:

For the standard Xinshiheng model, the listed operating temperature range is -40°C to 105°C, with PVC cable and customized length.
