The BYD B30 LFP LiFePO4 Battery Box utilizes lithium iron phosphate (LFP) as the cathode, enabling:
- Unmatched Safety: LFP’s thermal stability eliminates thermal runaway risks, making the battery box ideal for safety-critical uses like EVs or industrial energy storage.
- Long Lifespan: Designed for thousands of charge-discharge cycles, reducing total cost of ownership in long-term deployments.
- Cell-to-Pack (CTP) Design: Integrates 48 C115F cells in series without redundant modules, boosting energy density (167.5Wh/kg pack GED) and structural reliability.
Equipped with liquid cooling and single-cell temperature monitoring, this battery box ensures:
- Consistent performance across -30~55℃ discharge temperatures—vital for cold-region EVs or industrial gear in extreme climates.
- Automatic heating/cooling activation to maintain optimal cell temps, maximizing efficiency and cycle life.
The battery box features:
- IP68 Rating: Dust-tight and waterproof, allowing deployment in harsh environments (e.g., outdoor energy storage, construction machinery).
- High-Strength Casing: The top cover uses low-density, fire-resistant glass fiber prepreg (PCM process), balancing weight reduction with fire safety—critical for automotive and industrial applications.
Integrated single-cell voltage monitoring and multi-layer protections (overcharge, over-discharge, overcurrent, short-circuit) provide:
- Real-time visibility into cell health for predictive maintenance.
- Automatic shutdown during unsafe conditions, protecting the battery and connected systems.
The BYD B30 LFP LiFePO4 Battery Box powers:
- Electric Vehicles (EVs): Buses, trucks, or specialty vehicles needing high safety, long range, and durable power (e.g., public transit, logistics fleets).
- Industrial Energy Storage: Grid-tied/off-grid systems for peak shaving, backup power, or renewable energy (solar/wind) integration.
- Heavy-Duty Equipment: Construction machinery, forklifts, or port cranes requiring high current output (up to 250A continuous) and rugged operation.
