In the rapidly evolving world of electric vehicles (EVs), electric bicycles (e-bikes) have emerged as a popular and sustainable mode of transportation. This case study explores the innovative design of an advanced battery system tailored for e-bikes, highlighting how the integration of specific battery parameters and design specifications perfectly aligns with the unique demands of electric bicycles.

Battery System Overview

The central focus of our e-bike battery system is a Lithium Iron Phosphate (LiFePO4) battery, chosen for its superior safety, long life cycle, and environmental friendliness. The core specifications of our battery system include:

  • Nominal Voltage: 48V
  • Capacity: 20Ah
  • Energy Density: 230 Wh/kg
  • Cycle Life: Over 2000 cycles at 80% Depth of Discharge (DoD)
  • Weight: Approximately 3 kg
  • Dimensions: Optimized to integrate seamlessly into the e-bike frame

Design Considerations for Low-Speed E-Bike Requirements

The design of our battery system prioritizes the low-speed, high-efficiency needs of e-bikes:

  1. Energy Efficiency: The high energy density of the battery ensures a longer range on a single charge, making it ideal for urban commuting and leisure rides.
  2. Power Management: A customized Battery Management System (BMS) efficiently manages power output, ensuring consistent performance at lower speeds and prolonging battery life.
  3. Safety at Low Speeds: The inherent stability of LiFePO4 chemistry minimizes risks like overheating, especially crucial at low-speed operations where cooling is less effective.

Addressing Other E-Bike Specific Needs

Our battery system design also caters to various other requirements of e-bikes:

  1. Lightweight and Compact Design: The slim profile and reduced weight contribute to the overall lightness of the e-bike, enhancing maneuverability and user comfort.
  2. Fast Charging: The battery system is capable of rapid charging, significantly reducing downtime and increasing convenience for users.
  3. Durability in Varied Conditions: The robust build of the battery allows it to perform reliably in diverse weather conditions, a necessary feature for outdoor vehicles like e-bikes.
  4. Smart Integration: The battery is designed for easy integration with smart e-bike systems, allowing for features like remote diagnostics, GPS tracking, and usage statistics.
