Service Overview
New Energy Vehicle DCDC (Used) Solution
Tested Before Shipping · Cost-Effective · Alternative to Expensive OEM Parts
In EV maintenance, the DCDC (DC-DC converter) is one of the core components.
Once it fails, common symptoms include:
• Low-voltage system not powered
• Battery not charging
• Vehicle cannot start
• System fault codes
However, in real repair scenarios, a key issue is:
👉 OEM DCDC units are very expensive
⸻
I. Why Choose Used DCDC?
Compared to brand-new OEM parts, used DCDC is often a more practical option:
✔ Lower cost
Significantly reduces repair expenses
✔ Strong practicality
Suitable for accident vehicles, out-of-warranty cars, overseas repairs, etc.
👉 Core idea:
Solve problems with a more reasonable cost
⸻
II. Not “Ship Directly” — But “Test Before Shipping”
A common concern:
👉 Can used parts work reliably?
Our principle:
All DCDC units are tested before shipment
⸻
III. Testing Scope (Core Assurance)
Before shipping, we perform functional checks:
✔ High-voltage input test
Confirm proper power-up
✔ Low-voltage output test
Verify stable 12V / 14V output
✔ Rectification & conversion
Ensure proper HV to LV conversion
✔ Operational stability
Avoid intermittent faults or abnormal protection
⸻
👉 Core objective:
Deliver “working components,” not “unknown-condition parts”
⸻
IV. Why Testing Matters
DCDC is central to the vehicle power system:
• Affects the entire low-voltage system
• Issues can be hidden
• No testing = high risk
👉 Value of testing:
✔ Reduce installation failure risk
✔ Improve repair efficiency
✔ Minimize repeat replacement cost
⸻
V. Suitable Customers
• Overseas EV repair workshops
• Used vehicle repair projects
• Accident vehicle restoration
• Regions where OEM parts are unavailable
• Cost-sensitive repairs
⸻
VI. Summary
In EV repair:
It’s not about using the most expensive parts, but using reliable and practical ones
Through:
✔ Used DCDC
✔ Pre-shipment testing
✔ Functional verification
You achieve:
👉 Lower cost + reliable usability
⸻
