Architecture

Battery architecture describes pack design, such as module-based, cell-to-pack or structural battery layouts. It matters because the battery sets the car's range ceiling, charging behaviour, weight, price and long-term risk. Read the number together with chemistry, cooling, usable capacity and warranty.

How to compare it

Architecture influences energy density, repairability, rigidity and manufacturing cost.

  • Start with usable capacity, not only gross capacity.
  • Connect pack size to consumption and charging curve.
  • Read chemistry and warranty before judging long-term value.

What changes it

Battery figures move with pack design, chemistry, buffer size, temperature control and the car maker's software limits.

  • Chemistry affects cost, durability, cold behaviour and charging habits.
  • Cooling affects fast charging and repeated high-load use.
  • Buffers affect usable energy and long-term protection.

Common trap

Highly integrated packs can be efficient and strong, but repair economics after damage may be different from modular packs.

  • Bigger packs can hide worse efficiency.
  • Gross and usable capacity are not interchangeable.

Architecture: inside the pack

The useful number is shaped by cell chemistry, hidden buffers, cooling and the warranty strategy.
