LFP Battery Pack for BYD Auto Seal U

1. Product Overview

The LFP Blade Battery, exclusively tailored for the BYD Seal U DM-i (2023–2026), is a cutting-edge lithium iron phosphate (LFP) power solution offering three pure electric range variants: 75KM, 112KM, and 160KM (CLTC). Developed in-house by BYD with its revolutionary blade-shaped cell design and CTB (Cell-to-Body) integration technology, this battery redefines safety, durability, and space efficiency for plug-in hybrid SUVs. Free of scarce nickel and cobalt比亚迪汽车, it delivers stable daily electric commuting capability, seamless hybrid powertrain compatibility, and exceptional thermal stability, fully aligning with global EV safety standards and providing a reliable, eco-friendly energy source for the BYD Seal U.

2. Key Features

Revolutionary Blade Cell Design: Ultra-thin, elongated LFP cells with a unique flat rectangular structure, boosting pack space utilization by over 50% vs. conventional batteries.

Three CLTC Pure Electric Ranges: 75KM, 112KM, and 160KM variants to meet diverse daily commuting and urban driving needs比亚迪汽车.

Unmatched Safety Performance: Inherently stable LFP chemistry (non-oxygen-releasing, slow heat generation); passed rigorous nail-penetration tests without fire/smoke (surface temp 30–60°C); structural honeycomb aluminum casing for enhanced crashworthiness.

Ultra-Long Cycle Life: Over 5,000 charge-discharge cycles with high capacity retention比亚迪汽车, far exceeding traditional ternary batteries.

Nickel & Cobalt Free: Uses abundant LFP materials, lowering costs and environmental impact比亚迪汽车.

CTB (Cell-to-Body) Integration: Seamlessly integrated with Seal U’s chassis, improving structural rigidity, weight distribution, and vehicle handling.

Efficient Thermal Management: Intelligent liquid cooling/heating system maintains optimal operating temperature (−40°C to 60°C), ensuring stable performance in extreme climates比亚迪汽车.

Fast & Convenient Charging: Supports AC slow charging and DC fast charging (30%–80% in ~30 mins), with regenerative braking compatibility.

Full Protection BMS: Advanced Battery Management System provides overcharge, over-discharge, over-current, short-circuit, and thermal runaway protection.
