Bosch's Esitronic 2.0: Diagnostic Software for Electric and Hybrid Vehicles

In an era where electric and hybrid vehicles are becoming increasingly prevalent on the roads, vehicle workshops face new challenges in servicing and maintaining these advanced powertrains. The specialized expertise and specific training required to handle high-voltage systems demand reliable diagnostic software to ensure the safety and efficiency of workshop technicians. Recognizing this need, Bosch has introduced a groundbreaking solution with its Esitronic 2.0 Online diagnostic software, covering well over 200 electric and hybrid vehicle models. Let’s delve into how this innovative software simplifies diagnostics, making it accessible and hassle-free for vehicle workshops worldwide.

With the surge in electric and hybrid vehicles, the safety of workshop technicians is of utmost importance when working on high-voltage systems. Isolating the high-voltage system is a crucial step to protect technicians from potential electrocution. Bosch’s Esitronic 2.0 Online provides comprehensive instructions for the vehicle-specific isolation process, adhering to manufacturer specifications and data. By following these guidelines, workshops can safely disconnect the high-voltage system, discharge residual current, and ensure that the vehicle cannot be switched on again. Verification and documentation of the absence of voltage are also integral to the process, allowing technicians to work confidently on or near high-voltage components.

One critical aspect of electric and hybrid vehicles is the state of their high-voltage battery, which tends to degrade over time, impacting its storage capacity. To address this, some vehicle manufacturers provide diagnostic data known as the “State of Health” (SOH) of the high-voltage battery. The Esitronic 2.0 Online diagnostic software now includes a dedicated “HV battery (SOH)” tab, enabling technicians to read and print out this information if the manufacturer provides corresponding data in the HV battery management system. This feature allows workshops to generate an SOH report, providing vehicle owners with specific details about the health of their high-voltage battery, expressed as a percentage compared to a new battery.

While Esitronic 2.0 Online offers comprehensive coverage for a wide range of electric and hybrid vehicles, it also addresses the unique diagnostic requirements of Tesla models. Tesla, known for its innovative approach to diagnostics, has specific features that need to be observed for successful diagnostics. For instance, on Tesla’s Model S and Model X, workshops must depress the brake pedal to access the CAN diagnostic functions. Bosch’s Esitronic software provides crucial information about these brand-specific requirements, ensuring technicians can efficiently and effectively perform diagnostics on Tesla vehicles. As Bosch continues to enhance its diagnostic software, more Tesla models, along with electric and hybrid models from other manufacturers, will be included in regular updates, further expanding its capabilities.

The introduction of Bosch’s Esitronic 2.0 Online diagnostic software has revolutionized the way vehicle workshops handle electric and hybrid vehicles. By incorporating extensive diagnostic coverage for over 200 models, this software eliminates the need for workshops to purchase separate licenses for electric and hybrid vehicle diagnostics. The ability to safely disconnect the high-voltage system, combined with accurate reading and documentation of the high-voltage battery’s state of health, enhances workshop technicians’ capabilities and ensures the safety and satisfaction of vehicle owners.
