Blade 2 battery එකේ විශේෂත්වය මොකක්ද?
what are the improvements of blade 2 battery over previous generation
The **BYD Blade 2.0 battery** introduces several key improvements over its predecessor:
**1. Higher Energy Density**
- **190–210 Wh/kg** energy density (vs. 150 Wh/kg in Gen 1), enabling **longer ranges** (potentially exceeding 1,000 km CLTC)[1][2][8].
- **Two variants**:
- **Short blade**: 160 Wh/kg, supports **16C discharge** and **8C charging** (~7.5-minute full charge)[2].
- **Long blade**: 210 Wh/kg, supports **8C discharge** and **3C charging**[2].
**2. Enhanced Efficiency**
- **20% lower power consumption** per 100 km and **3% longer range** due to optimized thermal management and structural design[2][3].
- **Smaller, lighter packs** for the same range, reducing production costs and freeing cabin space[1][2].
**3. Performance and Safety**
- **Faster charging**: Theoretical full charge in **7.5–11 minutes** (short blade)[2].
- **Improved safety**: Maintains resistance to thermal runaway (e.g., nail penetration test)[1][8].
- **Longer lifespan**: Expected to exceed Gen 1’s durability, though exact metrics are unspecified[2][8].
**4. Structural and Thermal Advances**
- **Honeycomb-like structural integrity** from cell-to-pack design, enhancing crash resistance[3][7].
- **Better heat dissipation** via thinner cells and larger surface area, critical for fast charging[3][5].
These upgrades position BYD to compete with solid-state batteries while leveraging cost-effective LFP chemistry[1][2].
