The OEM battery charger manufacturing process turns a customer's electrical and mechanical spec into a certified, volume-produced charger. JUXON Power, a professional lithium battery charger manufacturer based in Shenzhen, China, with complete OEM/ODM capability, runs the flow below for every project from 48W to 8000W.
1. Specification and design
It starts with your battery voltage, chemistry, connector photo and target quantity. The engineering team produces a schematic, MCU firmware and mechanical enclosure, then validates the CC/CV profile on a bench.
2. Prototyping and verification
A small prototype batch is built and electrically characterized: efficiency, ripple, thermal rise and protection trip points. This is where CAN bus / RS485 communication is tuned to your BMS.
| Stage | Key activity | Output |
|---|---|---|
| Design | Schematic, firmware, enclosure | Engineering sample |
| PCBA | SMT + through-hole assembly | Populated board |
| Potting | Conformal coat / epoxy fill | Weather-sealed module |
| Burn-in | 4–8h full-load test | Stable, de-risked unit |
| QC | IQC/IPQC/OQC, Hi-Pot | Test report |
| Certify | CE/FCC/UL per market | Certificate pack |
3. Volume production and QC
SMT and through-hole lines assemble the PCBA, followed by automated potting for IP-rated models. Every unit passes 100% pre-shipment electrical test plus full-load burn-in. See JUXON's facility and testing process.
4. Branding and packaging
Logo, label, firmware ID and retail/private-label packaging are applied per your brand book before carton consolidation.
FAQ
How long does OEM charger development take?
A standard derivative is often 2–4 weeks to samples; a fully custom ODM design typically runs 6–10 weeks including validation and tooling.
What is potting for?
Potting fills the enclosure with epoxy or compound to seal against moisture, vibration and dust — essential for IP65 outdoor and industrial chargers.
Can you match my BMS protocol?
Yes. CAN bus and RS485 profiles are adjustable so the charger handshakes with your BMS for controlled, data-rich charging.
Do you provide test reports?
Yes. IQC/IPQC/OQC plus burn-in records are available per batch, supporting traceability for regulated markets.
