Frequently Asked Questions
Do I need prior experience to attend the battery repair course?
This 3-day intensive course is designed for technicians with prior auto repair experience. Basic knowledge of electrical systems and high-voltage safety is helpful but not mandatory — Day 1 covers HV safety fundamentals before any hands-on work begins.
Can I independently repair battery packs after completing this course?
The course equips you with the skills to perform BMS diagnostics, insulation testing, cell testing and grading, module replacement, cell balancing, and comprehensive fault diagnosis. With proper tools and safety equipment, most graduates can handle common battery pack faults independently. Complex board-level repairs may require additional practice.
Which EV brands are covered in the battery training?
The training uses real battery packs and BMS systems from mainstream Chinese EV brands including BYD (LFP blade battery), CATL, and Gotion. Diagnostic procedures are applicable across brands that use similar BMS architectures.
What is the difference between the 3-day battery course and the 7-day complete course?
The 3-day battery intensive focuses exclusively on power battery systems — HV safety, BMS diagnostics, pack repair, cell balancing, and fault diagnosis. The 7-day complete course covers the full vehicle: HV safety, drive motors, charging systems, commercial vehicle systems, CAN networks, and battery systems. The 3-day course is ideal for technicians who want to specialise in battery repair quickly.
Does the 3-day course fee include accommodation?
No. The 3-day intensive course fee is CNY 8,000 per person and covers tuition, hands-on materials, English interpretation, digital materials, and the joint certificate. Accommodation and meals are not included, but we can recommend nearby hotels at preferential rates.
When are the upcoming 3-day battery course dates?
Battery repair intensive courses are scheduled monthly. Contact us via WhatsApp or email for the next available session date. Sessions are limited to 10 participants to ensure sufficient hands-on time with real battery packs.
How do I enrol? What is the payment process?
Enrolment is simple: (1) Contact us via WhatsApp or email to confirm your preferred session date. (2) We will send you a course outline and payment details. (3) A deposit secures your seat, with the balance due before the course starts. We accept WeChat Pay, Alipay, USDT, and Visa.
Who should NOT attend this course?
This course is not suitable for complete beginners with no automotive repair background. If you have never used a multimeter, never worked on a vehicle's electrical system, or are not comfortable with high-voltage safety concepts, we recommend starting with the 7-day complete training course which builds foundational knowledge from Day 1.
What tools and equipment do I need after the course to repair batteries?
To perform battery repairs independently, you will need: an insulation tester (megohmmeter, ≥1000V), a cell voltage/internal resistance tester, BMS diagnostic software (brand-specific or universal), a PCAN or similar CAN bus analyser, standard insulated hand tools (torque wrench, insulating gloves, HV mat), and access to replacement cells or modules. The course includes guidance on sourcing these tools — many are available through NEV Fix's parts network. For a complete breakdown of workshop setup costs and equipment tiers, see our 2026 EV workshop equipment budget guide (three tiers from ¥24,500 to ¥79,800). You can also search OE part numbers for specific replacement components.
