What makes a battery a Blade?

LFP is the cathode chemistry. Blade describes the elongated, flat-sided cell format and how BYD packages it. In the original Cell-to-Pack (CTP) design, the cells go directly into the battery pack with less intermediate module hardware. BYD claimed over 50% better space utilisation compared with its reference conventional LFP block-battery design. That figure refers to packaging. In Cell-to-Body (CTB) designs such as the European SEAL, the pack is integrated into the vehicle’s structure. CTP and CTB describe how the battery is built into a pack or car. BYD’s 2020 launch · BYD on CTP and CTB.

Three milestones and what the charging figures mean

• 2020 · Original Blade Battery. The HAN EV was the first production BYD to use it. The same Blade name later appeared on packs with different sizes and charging limits across battery-electric cars and plug-in hybrids. BYD’s first-model and rollout account.
• 2025 · Super e-Platform. BYD announced a 1,000 V platform and charging power of up to 1,000 kW for the new HAN L and TANG L in China. This is the 2025 vehicle-platform announcement. BYD’s Super e-Platform announcement.
• 2026 · Blade Battery 2.0 and FLASH Charging. The second generation retains LFP chemistry. BYD describes changes to the electrodes and cell materials that let lithium ions move more readily, and reports an energy density increase of about 5%. With compatible equipment, BYD reports 10–70% in 5 minutes and 10–97% in 9 minutes under normal conditions. Its cold demonstration started at 20% and reached 97% in 12 minutes at −30°C. The headline figure of up to 1,500 kW refers to the charger’s peak output on the Chinese-market connector. To compare charging times, match the start and end state of charge, temperature, vehicle and charger. BYD’s March launch · BYD’s DENZA launch and charger specification.

In Europe, DENZA introduced Blade 2.0 and FLASH Charging with the Z9GT. The European BAO 5 specification illustrates the range within the second generation. It lists a 31.8 kWh Blade 2.0 pack and a maximum of 100 kW DC. BYD announced a separate launch for its own ATTO 8 in Europe, with sales planned for Q1 2027 as of the October 2026 announcement. Check the local vehicle specification and station availability before planning a charge around the headline times. DENZA Z9GT · DENZA BAO 5 · BYD ATTO 8.

What was actually measured?

• Cell teardown. Gorsch and colleagues examined one Blade cell sourced from China in 2023. They identified an LFP cathode and a graphite anode. The cell measured 965 × 90 × 14 mm and the authors calculated energy densities of 160 Wh/kg and about 355 Wh/L. These are figures for the tested cell. The complete pack also contains an enclosure, cooling and electrical hardware. Gorsch et al., 2025, Figure 1 and Table 1.
• Whole-car charging. BYD’s European SEALION 7 specification gives the 82.5 kWh Comfort and Design AWD versions up to 150 kW DC, and the 91.3 kWh Excellence AWD up to 230 kW. In ADAC’s independent test of the Excellence AWD, 10–80% took 26 minutes. It recorded a brief peak of about 226 kW and averaged 173 kW over the session. The time and average tell you more about the stop than the peak alone. For comparison, BYD Europe lists the plug-in hybrid SEAL U DM-i with 18.3 or 26.6 kWh, depending on trim, and up to 18 kW DC.

• Blade 2.0 at a public charger. Frandroid measured 33–90% in 12 minutes on a DENZA Z9GT in France using a public 350 kW IONITY charger. This session began at a different charge level and used different equipment from BYD’s FLASH demonstration. Frandroid’s first-hand test.
• Safety demonstration. BYD reported no visible smoke or fire and a surface temperature of 30–60°C in its 2020 nail-penetration demonstration. The nail creates an internal short in the tested setup. BYD also describes a second-generation nail test during FLASH charging after 500 FLASH cycles, reporting no thermal runaway, smoke or fire in that test. Crash performance, the behaviour of a damaged pack and real-world fire rates are separate questions. BYD’s 2020 test description · DENZA’s Blade 2.0 test summary.

Charging, storage and warranty for your car

Use the handbook for your exact model, market and edition. For example, the Middle East & Africa ATTO 3 handbook recommends a full charge at least weekly and a charge from below 10% to full every three to six months. The GCC/Middle East & Africa SEAL 5 DM-i handbook specifies a weekly full charge via AC. Both editions recommend 40–60% if the car will be parked for more than seven days. For a DC charging comparison, record the start and end percentage, charging time, charger, outside temperature and whether battery preconditioning was used. ATTO 3 handbook, printed and PDF pp. 90–92 · SEAL 5 DM-i handbook, EN_V1-MEA (06.2026), printed p. 91, PDF p. 92.

BYD announced in January 2026 that eligible BEVs and Super Hybrids in the EEA, the UK and Switzerland are covered for eight years or 250,000 km, whichever comes first, with a 70% minimum State of Health (SOH). BYD Australia lists eight years or 160,000 km for the traction battery. Check your local written terms for eligibility and exceptions. The SOH threshold is a warranty criterion. To investigate a change in battery condition, start with a service diagnostic. The distance shown after charging is a driving-range estimate. Published laboratory cycle counts describe test results, and years of ownership or a particular odometer reading cannot be inferred from them alone.
