Australian Market Case Study

12-24V Wide Voltage Compatible Solution

Engineered for the Australian market to support both 12V utes and 24V heavy trucks, eliminating voltage fluctuation risks with true universal compatibility

Market Challenge: Australia's Unique Vehicle Environment

Understanding customer pain points is the foundation of effective solutions

The "Mixed Fleet" Voltage Dilemma

The Australian automotive market presents a unique "dual-voltage" landscape. Popular ute models like Toyota HiLux and Ford Ranger operate on 12V electrical systems, while heavy trucks, construction machinery, and specialty vehicles use 24V systems.

This "mixed fleet" reality creates significant challenges for parts suppliers—customers need a single lock solution that works across both voltage specifications, not separate products for each application.

"Voltage compatibility isn't optional—it's a hard requirement in the Australian market."

Technical Pain Points: Voltage Fluctuation & Burnout Risks

The critical challenges facing traditional 12V locks in vehicle environments

Alternator Voltage Spikes

Vehicle alternators generate significant voltage fluctuations under different operating conditions. When charging batteries, voltage can spike to 15V or higher, far exceeding the tolerance of standard electronic components.

Costly Burnout Failures

Traditional 12V locks lack sufficient voltage tolerance margins. Without proper surge protection, control chips and motor windings easily burn out during voltage spikes, resulting in high failure rates, frequent complaints, and expensive maintenance.

Our Solution: Redefining Wide-Voltage Architecture

End-to-end technical upgrade from chip selection to motor matching

Industrial-Grade Wide-Voltage Chip

Re-selected control chips supporting 10V-30V input range with integrated over-voltage protection, under-voltage lockout, and surge suppression circuits to handle alternator fluctuations with confidence.

High-Performance Wide-Range Motor

Matched with DC motors featuring extended voltage operating ranges, ensuring stable and powerful torque output under both 12V and 24V supply conditions while maintaining controlled temperature rise.

Rigorous Validation Testing

Validated through extended burn-in tests and extreme condition verification, ensuring stable operation in harsh environments with near-zero failure rates.
