YILIE Technology is a BMS-Centric Power Solution Partner and integrated manufacturer. Powered by our proprietary Smart BMS technology, we combine in-house BMS/PCB engineering, embedded firmware, power electronics, industrial design, system integration, and advanced manufacturing.

We provide both ready-to-market power products and application-specific turnkey development for global brand owners, distributors, wholesalers, and fleet operators across three core sectors:
• Automotive Emergency Power (12V/24V Jump Starters & Commercial Fleet Starters)
• EV Charging Solutions (Portable EV Chargers & Smart Wallbox Stations)
• Portable & Backup Energy Solutions (Power Stations, RV Battery Packs & Accessories)

We are both an engineering-driven development partner and an integrated physical manufacturer.

Standard Sourcing:
• Customers can source our existing mature, ready-to-market product platforms for rapid market entry.

Private Labeling:
• Fast branding on existing platforms (custom casing color, logo, UI boot screen, and packaging).

OEM / ODM Co-Development:
• Full-stack custom development from initial concept, custom BMS architecture, PCB layout, and tooling to pilot run and mass production.

Ja, absolutely. YILIE offers a comprehensive catalog of tested, certified, and ready-to-market product platforms. Global distributors and retailers can directly select existing models and choose the desired level of branding (from neutral standard supply to complete private label packaging).

Our core foundation is our proprietary Smart BMS (Battery Management System) technology.

Unlike conventional assemblers that rely on generic off-the-shelf protection boards, we develop hardware, firmware, and power electronics in-house. This BMS-centric approach allows us to optimize discharge curves, thermal dissipation, cycle life, and multi-layer safety mechanisms specifically matched to high-drain automotive and EV charging applications.

Ja. Our engineering team can develop custom BMS architectures and complete product integration tailored to your exact performance parameters:

Electrical Parameters:
• Working Voltage (12V, 24V, 48V, multi-voltage switching), Continuous & Peak Current (up to 4000A), Charging/Discharging Power.

Smart Features:
• Communication protocols (DÜRFEN, RS485, Bluetooth, Wi-Fi, App integration), LCD/OLED display UI, smart state-of-charge (SoC) algorithms.

Environmental & Safety Requirements:
• Extreme ambient operating range (-30°C to +60°C), waterproof/dustproof ratings (up to IP66), vibration resistance for commercial fleets and marine use.

YILIE jump starters are equipped with 10-layer intelligent BMS safety protections:
1. Reverse Polarity Protection (with audible and visual alarm)
2. Reverse Charge Protection (prevents vehicle alternator back-feeding)
3. Over-Current Protection
4. Over-Voltage & Surge Protection
5. Short-Circuit Protection (instant cutoff < 1ms)
6. Over-Discharge Protection
7. Over-Temperature & Thermal Runaway Protection
8. Spark-Proof Technology (safe connection even when clamps touch)
9. Low-Voltage / Deep-Discharge Force Start Activation
10. AI Battery Health & Impedance Detection

Ja. We specialize in high-discharge, multi-voltage (12V/24V auto-detect or manual switch) heavy-duty jump starters delivering peak currents up to 4000A. These systems are engineered to reliably crank up to 16.0L diesel commercial engines, semi-trucks, mining machinery, agricultural equipment, and marine vessels even under severe sub-zero winter temperatures (-30°C).

We offer three flexible cooperation tiers:

Tier 1 — Private Label (Light Customization):
• Custom logo printing/engraving, custom casing colorways, customized retail gift box, multilingual user manuals, and customized clamp/cable accessories.

Tier 2 — OEM (Specification Tuning):
• Modifications to battery capacity, peak current output, port configurations (e.g., 65W/100W PD USB-C), display screen interfaces, and market-specific plug standards.

Tier 3 — ODM / Turnkey Development:
• Ground-up industrial ID design, structural engineering, custom tooling & injection molding, dedicated BMS schematic & firmware coding, prototype validation, and international certification filing.

Quality control is strictly integrated across the entire product lifecycle following ISO9001 quality management standards:

IQC (Incoming Quality Control):
• 100% testing of incoming high-rate lithium cells (internal resistance, capacity, voltage consistency) and critical electronic components.

IPQC (In-Process Quality Control):
• Automated SMT assembly inspection, ultrasonic welding verification, and semi-finished PCB functional checks.

100% Aging & Load Testing:
• Every single assembled unit undergoes full-capacity load testing and high/low temperature burn-in cycles.

FQC & OQC (Final & Outgoing Quality Control):
• Drop testing, vibration testing, casing IP rating checks, and pre-shipment AQL sampling inspection.

Our products are engineered and certified to comply with mandatory safety, electromagnetic compatibility (EMC), environmental, and hazardous goods transportation regulations across North America, Europe, Australia, and other global markets:

North America:
• UL 2743 (Jump Starters), UL 2594 / SAE J1772 (EV Chargers), FCC, ETL.

European Union:
• CE (EMC / LVD), RoHS, REACH, IEC 62133, IEC 62752 / EN 61851 (EV Charging).

Transportation & Battery Safety:
• UN38.3 (Lithium Battery Transport Safety), Sicherheitsdatenblatt, 1.2M Drop Test Reports, and Sea/Air Freight Dangerous Goods Declarations.

Note: Specific certification test reports and declarations of conformity (DoC) are provided based on the exact model and destination country requirements.

Our MOQ is tiered according to the customization depth and product category:

Sample Orders:
• Available from 1 unit for quality and market evaluation.

Standard / Neutral Packaging:
• Starting at 100 units (standard stock configurations).

Private Label Branding:
• 300 – 500 units (custom logo on casing, custom packaging, and customized manual).

Deep OEM / ODM Tooling:
• Typically 1,000 units (custom enclosure tooling, custom BMS firmware, or unique industrial design).

Ja. We strongly encourage sample testing prior to volume commitment:
