EV Master focuses on the diagnosis and health status detection of new energy vehicle battery packs, integrating fault diagnosis, data stream reading, temperature and voltage monitoring of battery packs, and supporting one click generation of health reports. โ Fault diagnosis: We automatically scan the entire vehicle system of new energy vehicles and support one click clearing of fault codes. โ Read data stream: Supports reading battery pack related data streams for users to view battery related information in real time โ Battery pack inspection: Read the voltage and temperature of each battery in the new energy vehicle, and grasp the health status of each battery. Battery Health Report: It covers basic information about the battery (remaining charge, health status) and inspection details (fault conditions, battery voltage and temperature, data flow information), assisting users in understanding the battery condition of their car.
Electric Scan

Electric Scan turns your phone into a live window on your EV's high-voltage battery. Pair it with the Electric Scan Bluetooth LE module, connect the module to your vehicle, and the app streams what the battery management system reports, refreshed several times a second. CELL VOLTAGES Every cell in the pack, read individually. Switch between a numeric grid and a heatmap that shows at a glance where each cell sits within the pack's own minimum-maximum range. The summary panel identifies the highest and lowest cell by number, the pack average, and the spread between them in millivolts. PACK AND STATE State of charge, state of health, total pack voltage, module temperatures, and 12 V system voltage, each on its own level bar. DRIVE DATA Motor RPM on a 270-degree gauge, actual against requested torque on a bipolar meter that separates drive from regeneration, and GPS speed from your phone. TRIP RECORDER Start a recording before you set off and the app samples speed, RPM, state of charge, and torque for the whole trip. Afterwards you get distance, top and average speed, peak RPM, and the change in state of charge, with a chart for each channel. Trips are stored on your device and you choose which ones to keep or delete. G-FORCE METER A live readout of acceleration, braking, and cornering forces measured by your phone's motion sensors, with a trail of recent movement and a peak hold. LANGUAGES Thai and English. REQUIRES HARDWARE Electric Scan is a companion app for the Electric Scan Bluetooth LE module and does nothing on its own. Without the module connected to a vehicle you will only see the connection screen. IMPORTANT Electric Scan displays the values your vehicle makes available. It is a reference tool for the owner, not a repair tool, and it cannot repair or resolve high-voltage battery issues. The readings shown are preliminary reference information only and are not a substitute for an official diagnosis by an authorised service centre or a qualified technician.

Verdict
EV Master and Electric Scan are too close to call on the numbers: across 5 compared parameters โ price, ads, in-app purchases and device support among them โ neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
