Introduction to Traction Batteries

Traction batteries, often referred to as electric vehicle batteries, are specifically designed to power the propulsion systems in electric vehicles (EVs) including electric cars, trains, and e-bikes. Unlike traditional lead-acid batteries, these are built for durability, longevity, and power density.

Applications of Traction Batteries

Traction batteries are utilized in a range of vehicles:

• Electric Cars: Used in personal and commercial vehicles, providing a more sustainable mode of transport.
• Trains: Powering locomotives and trams for urban and suburban rail systems.
• E-Bikes and Scooters: Increasingly popular for personal mobility, these vehicles rely on efficient and light traction batteries.
• Industrial Equipment: Utilized in forklifts and other warehouse equipment, offering zero-emission operation.

Technology and Composition of Traction Batteries

Typically, traction batteries are made from lithium-ion chemistry due to its high energy density, efficiency, and life cycle. They are composed of several individual cells arranged in modules which are connected to form packs. Key components include:

• Anode and Cathode: Determining capacity and voltage.
• Electrolyte: Facilitating the flow of ions between anode and cathode during charge and discharge cycles.
• Battery Management System (BMS): Ensures optimal usage, performance, and lifespan of the battery by monitoring and regulating key parameters.

Performance Metrics and Parameters

The performance of traction batteries is measured through various parameters, including:

• Energy Capacity: Typically measured in kilowatt-hours (kWh). For instance, a Tesla Model S battery pack has an energy capacity of approximately 100 kWh.
• Charging Time: Influenced by the charging technology. Fast chargers can charge up to 80% in approximately 30 minutes.
• Cycle Life: Number of complete charge/discharge cycles before capacity drops below 80%. High-quality batteries often offer a cycle life exceeding 1000 cycles.
• Energy Density: Measured in watt-hours per kilogram (Wh/kg). Leading lithium-ion batteries can achieve energy densities upwards of 250 Wh/kg.
