Launch X431 EV Expansion Kit – Diagnostic Add-On for Electric and Hybrid Vehicles

The Launch X431 EV Expansion Kit is designed for professional EV technicians, automotive electricians, diagnostic specialists, independent workshops, battery repair specialists, hybrid-vehicle technicians, and service centers that are expanding into electric mobility. Its combination of high-voltage battery diagnostics, BMS analysis, SOC/SOH information, individual cell voltage and temperature monitoring, multiple battery connection methods, dedicated EV adapters, and broad EV brand coverage makes it a valuable upgrade for compatible Launch X431 diagnostic platforms.

No. Battery-pack analysis, individual cell information, SOC, SOH, BMS access, charging-system diagnostics, and other EV-specific functions depend on the vehicle manufacturer, model, production year, battery manufacturer, BMS architecture, connection method, compatible adapter, and current Launch software coverage. Compatibility should therefore be checked for the exact vehicle and required function before purchase.

Yes. Battery diagnostic results can be used to create professional reports that can be saved, printed, and shared, depending on the connected Launch scanner. This is useful for documenting battery condition for customers, workshop records, pre-purchase inspections, or repair verification.

The EV diagnostic upgrade package is supplied with an activation card/software authorization in applicable configurations. After activation on a compatible Launch scanner, the dedicated New Energy/EV diagnostic functionality becomes available for supported applications.

No. The EV Expansion Kit is an add-on rather than a standalone diagnostic tablet. It is designed to work with a compatible Launch X431 diagnostic device and the appropriate EV diagnostic software. The kit expands the capabilities of the existing scanner for EV and high-voltage battery diagnostics.

Current compatibility information includes professional Launch platforms such as X431 PAD V, PAD VII, PRO5, V+ 5.0, PRO3S+ V5.0, PRO3S+ Elite, PRO3 V+ Elite, PRO3 ACE, and PRO3 APEX. Compatibility should always be confirmed for the exact scanner version before purchase.

Yes. Tesla is included among the electric-vehicle brands listed in Launch’s EV diagnostic coverage. Available functions depend on the particular Tesla model, battery configuration, software, and required connection method.

Launch lists battery-pack coverage for manufacturers including CATL, Gotion/Guoxuan, CALB, BYD, SVOLT, E-POW, RN Tech, Colight, and other supported battery systems. This is particularly useful because the same battery technology may appear across multiple EV manufacturers and models.

Published Launch Europe coverage includes EV applications from manufacturers such as Volkswagen, BMW, Mercedes-Benz, Audi, SEAT, Škoda, Ford, GM, FCA, Tesla, BYD, NIO, Chery New Energy, BAIC New Energy, XPeng, Li Auto, Leapmotor, Roewe, and others. Exact coverage depends on the model, year, battery system, and software version.

Launch Europe specifies that the diagnostic add-on set includes 25 adapter cables for connecting to high-voltage battery systems, together with jumper cables. Launch states that this combination provides more than 95% vehicle coverage within its supported applications.

The Launch EV Expansion Kit supports several battery diagnostic methods, including dedicated battery adapter cables, 16-pin OBD diagnostics, and jumper-cable diagnostic connections. This flexibility allows technicians to work with different EV battery architectures and connection designs.

Yes. Depending on the vehicle and software coverage, the EV diagnostic platform can provide access to additional electric-vehicle systems such as electric drive control, charging systems, energy-management systems, and regenerative-energy systems. Available functions vary according to the vehicle manufacturer and architecture.

Yes. BMS diagnostics are an important part of the Launch EV diagnostic platform. The kit helps technicians access battery-related information and analyze the electronic systems responsible for monitoring and managing high-voltage battery operation.

Yes. The EV Expansion Kit can retrieve battery temperature information from supported systems, including available temperature data for individual battery modules. Monitoring temperature differences can help technicians identify abnormal operating conditions within a high-voltage battery pack.

Yes. On supported battery packs, the system can display individual cell voltage, helping technicians identify cells or modules whose voltage differs abnormally from the rest of the battery pack. This is especially useful when investigating battery imbalance or performance problems.

Yes. State of Health (SOH) information can be read from compatible battery systems. SOH helps technicians evaluate the overall condition of the traction battery and can be particularly useful when diagnosing battery degradation or evaluating a used electric vehicle.

Yes. The EV Expansion Kit can retrieve State of Charge (SOC) information from supported high-voltage battery packs. SOC indicates the battery’s current charge level and is an important parameter when diagnosing charging, range, and battery-management problems.

Yes. Battery-pack diagnosis is one of the kit’s most important functions. On supported vehicles and battery systems, technicians can retrieve detailed battery information and analyze the condition of individual modules and cells.

The main purpose of the kit is to give professional technicians deeper diagnostic access to EV and hybrid high-voltage systems, particularly the traction battery and Battery Management System (BMS). It helps workshops evaluate battery condition, identify abnormal cells or modules, and analyze important battery operating parameters.

The Launch X431 EV Expansion Kit is a professional diagnostic add-on designed to expand compatible Launch X431 scanners for advanced electric and hybrid vehicle diagnostics. It provides specialized adapters and EV diagnostic software for accessing high-voltage battery systems and other EV-specific electronic systems that require more than conventional OBD diagnostics.
