Importance of Temperature Management in Automobiles

With the advancement in technology, our automotive industry has seen so many changes from regular petrol-operated vehicles to ones using diesel as fuel to the latest electric power charged vehicles. With growing needs, the automotive industry has focused immensely on upgrading and making the systems better. Evidently, “temperature” is a very important parameter for the proper function of an automobile. May it be petrol or diesel-fuelled or electric. But, is appropriate to say that temperature management is mandatory to consider in electrically operated vehicles. Where the batteries are susceptible to temperature variations, and it needs to be monitored ideally.

In general, atmospheric conditions can be problematic too. Cold, heat, and even humidity can bring considerable variations in the output of your automobile. However, they play a vital role in enabling many components to function correctly or as intended. Like, when the temperature is too low, it becomes highly problematic to get the engine running. May it be diesel or petrol, the fuel does not burn properly, resulting in higher emissions. In an EV, around/below 5°C, an electric battery cannot be charged optimally, and below -40°C, a battery seizes to function at all. Similarly, overheating has its horrors; power loss, damage to the vehicle, blaze, or even explosions. Temperature parameters of all the other components need to be monitored and managed.


May it be the vehicle's overall temperature, the temperature of the surroundings or from the various components like the spark plug, cylinder heads, exhausts, or any other part, all are equally important for a vehicle’s health at the time of development and when on the road. Accurate temperature information allows the engineers to study the temperature in various parts of the control system, monitor their performance, and maximise their efficiencies no matter the driving conditions. And, for so at “Influx”, we bring you our K-TC from our K-series for accurate temperature sensor measurement data for CAN applications.

As evident from the above images, K- TC provides you with all the temperature measurements through a thermocouple. The K-TC modules belong to the Influx K-series instrumentation range for CAN applications. Therefore, the stackable K-TC is ideal for those applications that require a large number of thermocouples, for example, vehicle durability, winter and summer testing. The K-TC modules CAN Bus settings, calibration and sampling rates are all easily configurable and stored in the K-TC module even when not powered. In addition, the K-TC modules can function as a standalone temperature logger with an inbuilt Micro SDHC storage, and the data is logged with an accurate timestamp using the internal RTC.

  • The input calibration and set-up of the K-TC module are easily configurable via Influx K-Cal software, a freely distributable Windows pc application. Modular temperature measurement for any amount of thermocouple.

  • Highly accurate thermocouples measurement accuracy of ±1°C, and measurement resolution of 0.1°C.

  • Cold Junction compensation for accurate thermocouple measurement.

  • Up to 8, 16, 32 thermocouple connections on each device, at a 10Hz sample rate.

  • Configuration and programming via CAN or USB interface.

  • Simple signal configuration using a DBC file.

  • Supplied with configuration software’s Influx K-Cal (Configuration) and TCLogger (Datalogging) for Windows.

  • Device drivers are available for Windows® applications (32/64-bit).

  • WakeOnCAN enables K-TC modules to power up and power down in deep sleep mode.

  • Instrumentation data time synchronised with recorded vehicle network data via CAN.

  • Galvanic isolation (enclosure, power, CAN BUS and each module of 8 thermocouple inputs).

  • Stackable ABS enclosure.

  • Standalone logging capability.

  • Supports K, j and T types of thermocouple, with a -200 to 1200°C range.

  • Simple signal configuration using a DBC file.

  • Internal micro-SD card.

  • Maximum input voltage ±3.3 V.
