The Panasonic Ncr21700t Datasheet is more than just a document; it’s a comprehensive guide to understanding one of the most popular and versatile lithium-ion battery cells on the market. This datasheet provides critical specifications, performance characteristics, and safety information essential for engineers, hobbyists, and anyone designing or working with battery-powered devices. Let’s explore the depths of what the datasheet unveils.
Understanding the Panasonic Ncr21700t Datasheet
The Panasonic Ncr21700t Datasheet serves as the primary source of truth for all things related to this specific battery cell. It meticulously outlines the cell’s electrical characteristics, such as nominal voltage (typically 3.6V or 3.7V), capacity (around 4800-5000mAh), and internal resistance. Beyond these basic specifications, the datasheet delves into charge and discharge characteristics, providing recommended charging currents, discharge cut-off voltages, and temperature limits. This information is crucial for designing battery management systems (BMS) that ensure optimal performance and longevity of the cell. Understanding these parameters is paramount to preventing overcharging, over-discharging, and thermal runaway, all of which can damage the battery or create hazardous conditions.
Datasheets are used by various people in various roles. For example:
- Engineers designing power tools need to know the maximum continuous discharge rate.
- Electric vehicle (EV) manufacturers require detailed information on cycle life and energy density.
- Hobbyists building custom battery packs rely on the datasheet for safe handling and charging instructions.
The datasheet typically includes graphs illustrating the cell’s performance under different conditions. These graphs might show discharge curves at varying current levels, cycle life performance at different depths of discharge, and the impact of temperature on capacity. It will usually outline critical safety information, including handling precautions, storage recommendations, and warnings against misuse or abuse. Example of storage recomendations:
- Ideal storage temperature range: 10°C to 30°C
- Recommended state of charge (SOC) for long-term storage: 30% to 50%
- Avoid storing in direct sunlight or high humidity environments
Furthermore, the datasheet often includes mechanical drawings outlining the cell’s dimensions and weight. These measurements are vital for designing battery holders and enclosures that properly accommodate the cell. The table below shows some mechanical characteristic of the cell:
| Parameter | Value |
|---|---|
| Diameter | 21.1 mm (max) |
| Length | 70.3 mm (max) |
| Weight | Approximately 69 g |
