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.
