EV Testing Data Logger (2022) - Electric Vehicle Data Logger | Telematics | BMS & Fleet Tracking

Updated: May 10

Electric vehicles have soon become the new reality of the Automotive industry. Blame the skyrocketing prices of petrol/diesel or increasing CO2 emissions, or depleting fossil fuels around the globe; anything or everything seems to have only led to a quick evolution of the automotive industry. Roads have gotten filled with EVs, even way before the anticipated time. And within days after entering the markets, this technology has shown wild-fire like advancements. Talking about the technology, the auto industry is already in the era where a standard vehicle also uses 100+ ECUs for proper functionality; with EVs coming into the picture, this number has increased multi-folds.



With this massive turn in technology, the introduction of rechargeable batteries, and the addition of many other technically complex elements, the need to collect data for making these vehicles perform better has also increased.


An electric vehicle needs a data logger way more than a conventional vehicle, as a more significant number of ECUs means massive data to calibrate.

Various parameters need to be monitored for better performance, such as SOC, SOH, voltage, current, charging voltage, charging current, cell voltages, cell temperatures, and something that aids and becomes an integral part of the BMS of the vehicle. This enables the user to analyse data and troubleshoot to improve their vehicle’s performance.


Main features to keep in mind while choosing a data logger for an EV:


The existing market of datalogger technology is also colossal today. There exist many such loggers which might look promising enough to fulfil the basic criteria. But for selecting one such logger that does it all, one needs to keep a few important pointers in mind.


Configuration: for any device, the most critical is the configuration around which it is built. There seems less logic in paying for something not required or paying for a device that misses out on any of the features you are looking for. The most important features to look out for in an electric vehicle data logger can be GNSS, gyroscope, accelerometer, collection of battery temperatures, embedded eMMC, cloud storage, open platform, etc.


Accessibility: the other major factor to keep in mind is the easy accessibility of the device. Using something with a great configuration might become useless if the user struggles to put the device to work. Various accessibility functions to consider when buying a logger can be easy usage, hassle-free interfacing, freedom to design the config etc. Some advanced features must also support multiple file formats, triggers, live-data viewing, Wakeup-on CAN/Wake-on moment, sleep modes, start/stop logging flexibility, etc.


Reliability: now, along with the above mentioned two features, reliability is equally important. What if a product had it all, worked the way you wanted it to but gave you inaccurate readings? Factors that make a device reliable enough can be accuracy, cost-effectiveness, compactness, no data loss, robustness, security etc.


Reading these points may trick you into thinking, “wait, which logger in the world will have all these?” but what if we told you that, Influx offers you just exactly what you need.



EV Data logging made simple with ReXgen Series:



ReXgen Series has been there for quite some time to take care of the regular conventional vehicle. May it be two, three or four-wheelers, our data loggers from the ReXgen Series have taken care of all their data logging needs. And with the automobiles transforming into electric beasts, ReXgen has also transformed to support them completely. ReXgen dataloggers not only support the features and characteristics mentioned above but many more.


ReXgen, in a nutshell, is a device that will support it all. A cost-effective solution that:


  • Plug & Play - Easy configuration.

  • Robust & IP65 rated.

  • Easily Mountable & compact ergonomic design.

  • Low power consumption & Wake on CAN/Signal Feature.

  • Supports up to 32GB of eMMC storage.

  • Supports CAN/CAN FD.

  • Capable of telematics and fleet management.

  • Offers Open API.

  • Works as a pass-thru device.

  • Supports multiple file formats.

  • CAN frame error detection.

  • Apply triggers to start/stop logging by defining your custom time.

  • Supports 4G (LTE) connectivity to transfer data to the cloud. (AIR)

  • Encrypts data logs using Advanced Encryption Standard (AES).

  • Enables Locking of the device using RSA data security.

The other most incredible characteristic that compliments the existence of the ReXgen data loggers is the ReXdesk software. ReXdesk is entirely free and dedicated software explicitly designed to support ReXgen throughout its life cycle. It enables the user to prepare and configure the ReXgen loggers for data logging. Using ReXdesk, the user can retrieve, convert, view live data, etc.

The user can also program the ReXgen device using third party software with the help of the open XML file available. Also, the open API feature lets the user configure the device according to their need. Leading to higher gains, business expansions, better time utilization and lesser need for support.
