Clean. Quiet. Completely Mobile.
At Battery Power Industries (BPI), we believe innovation doesn’t just improve performance — it transforms industries. Our recent collaboration with TMCW showcases this perfectly: a fully self-contained, battery-powered mobile car wash designed for maximum efficiency, flexibility, and environmental sustainability.
Built with cutting-edge lithium technology and engineered to TMCW’s exact specifications, this mobile setup allows full car washing and detailing services without relying on external power — no generators, no noise, and zero emissions.
Performance Meets Practicality
The TMCW mobile wash van houses:
- A massive onboard vacuum and water tank for extended operation
- Integrated compressors for water pressure and air tools
- Smart cable and hose reel systems for quick, tidy deployment
- Custom control interface with simple monitoring and system management
Every element of this build was designed, installed, and tested by BPI’s engineering team, ensuring safety, reliability, and seamless functionality — all powered by clean energy.
Technical Insight: How the System Works
While the concept is simple — bring power wherever you go — the engineering behind it is anything but.
This system is built around a 12-kWh lithium battery pack, designed for high discharge efficiency and long cycle life. It provides sufficient power to run the car wash system for extended periods, including pumps, compressors, and auxiliary equipment.
Core Electrical Components
- Battery Pack: 12 kWh LiFePO₄ configuration with BMS monitoring for voltage, temperature, and current stability.
- Inverter System: Victron Multiplus inverter ensures pure sine-wave output and smooth AC delivery to all onboard systems.
- Solar Integration: A Victron MPPT charge controller optimizes input from a PV module, extending operational autonomy, and reducing the need for shore charging.
- System Control: Intelligent energy routing allows simultaneous use and charging, with safety interlocks and overload protection.
Mechanical Setup
The van’s rear compartment integrates all components within a precision-mounted stainless steel frame. The large vacuum and water tank sit at the center for balanced weight distribution, with high-flow pumps and air compressors installed for consistent performance. Reel-mounted hoses ensure fast setup and compact storage — ideal for mobile service teams.
Efficiency. Independence. Sustainability.
The result is a truly mobile, off-grid washing system capable of professional-grade performance wherever the job takes you. TMCW now operates with reduced operating noise, zero fuel dependency, and a smaller carbon footprint — all while maintaining industrial reliability and speed.
At Battery Power Industries, we’re proud to deliver not just power systems — but complete energy solutions designed around how our clients work.
Smart. Silent. Sustainable.
That’s the BPI difference.
