Vehicle-to-Load (V2L) Inverter from an E-Bike Battery Pack

Approx. component budget: Rs. 7,000 - 12,000

Objective

Show how an EV battery can power emergency loads and measure efficiency and runtime.

What you will build

An inverter powering small AC loads (lights, a fan, a laptop) from a 36 V or 48 V e-bike battery, with low-voltage cut-off and overload protection.

Results you can expect

• Efficiency vs load
• No-load consumption
• Runtime at 100 W
• Output waveform quality
• And protection trip tests

What you will learn

High-voltage DC systems, inverter protection and battery cut-offs.

Tools and notes

Ready inverter module or a self-built H-bridge with SPWM, battery pack with BMS, power meter, scope. 230 V output is dangerous: use enclosure, fuses and supervision.

Resume points from this project

• Built and tested Vehicle-to-Load (V2L) Inverter from an E-Bike Battery Pack; objective: show how an EV battery can power emergency loads and measure efficiency and runtime.
• Measured and analysed efficiency vs load and no-load consumption; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
