This shift signals a new era in EV diagnostics for the global aftermarket.

HV System Diagnostics: Do OE-Level Diagnostic for HV System

ev box HV System Diagnostics

High-voltage system diagnostics provide comprehensive solutions for Electric Vehicles (EVs)

As electric vehicles continue to rise in popularity for both personal and business use, conventional diagnostic tools are limited by their configurations and cannot effectively diagnose the HV system of new-energy vehicles, retrieve detailed battery pack information, or check electric controllers. That's where high-voltage system diagnostics come in, providing advanced diagnostic capabilities specifically designed for EVs to ensure proper maintenance and repair.

1. Efficient High-voltage Component Diagnostics

The Autel EV Box allows the Autel Ultra/MS919/MS909 auto scanner to perform comprehensive diagnostics on high-voltage components such as battery packs, electric controllers, and motor controllers.

2. Automated High-voltage System Scanning

This includes reading and erasing diagnostic trouble codes (DTCs), generating diagnostic reports, and component replacement.

3. Accurate Battery Pack Analysis

A single click provides information on battery status, including State of Charge (SOC), State of Health (SOH), voltage, current, temperature, and live data of motors and compressors. Active tests can also be performed to quickly locate vehicle problems.

4. Effective Diagnostic Solutions

All high-voltage systems are integrated into one module, allowing for quick differentiation between high-voltage and low-voltage systems. In-depth block diagrams of the HV system, professional term descriptions, and safe operation guidelines help ease diagnostic complexity.

5. Wide Range of Coverage for Global EV Vehicles

Autel EV Box supports a range of global EV vehicles, including BMW, Mini, VW, Skoda, Tesla, Ford, Chevrolet, Cadillac, Buick, GMC, Honda, Toyota, Lexus, Nissan, Hyundai, KIA, Renault, BYD, and more.

Battery Pack Diagnostics: Do Professional Battery Diagnostics

EV Vehicle Battery Out-of-Vehicle Check

  • If the battery component is unable to communicate with the vehicle's computer, the Autel EV Box allows you to remove the battery from the vehicle and perform independent testing.
  • The battery pack test makes it easy to determine whether the battery has been repaired properly without wasting time disassembling the battery from the vehicle and going back and forth.

EV Vehicle Battery Pack Diagnostics

  • The Autel EV Kit provides three ways to connect vehicle batteries: OBD, specific cables (for BMW, VW, Tesla, etc.), and jumper cables. The on-screen tips guide you to choose the right cable for your needs.
  • With just one click, you can directly read battery information such as State of Charge (SOC), State of Health (SOH), Voltage, Current, Temperature, etc. The graphical presentation of battery status provides intelligent battery maintenance recommendations.
  • The Autel EV Kit can identify any faults or defects in the battery cells or modules that may impact the safety of the vehicle.
  • The kit can detect any abnormalities in the charging or discharging behavior of the battery pack, which could indicate a problem with the charging system or the battery itself.
  • The Autel EV Kit provides feedback to the driver or the vehicle's control system to optimize the use of the battery pack and extend its lifespan.
  • The Autel EV Kit is widely compatible with various electric vehicles from brands such as Mini, VW, Skoda, Audi, Tesla, Honda, Nissan, Lexus, Renault, and more.

David (United States)
Excellent tool for the price

Electrical Vehicles are here and I do not want to leave money on the table for everyone elseand I gave it a 5 star for coverage and connectors.

Gabriel R. (United States)
Works great with my Ultra

I purchased the Autel Ultra two years ago without knowing that an Autel Ultra EV would be released later. However, as I've started to receive more clients with new energy vehicles from Tesla, Chevrolet, Ford, Toyota, and Lexus, I realized that I needed a way to diagnose them. After conducting extensive research and watching numerous YouTube videos, I discovered that all I needed to do was purchase the EV kits to connect to my existing Ultra scanner. This has allowed me to directly diagnose the battery pack and effectively service these newer vehicles.
