Accelerating rate calorimetry

A test in which a cell sits in an adiabatic chamber that follows its temperature, so any self-heating is not lost to the surroundings. It measures the onset temperature, the self-heating rate and the temperature at which runaway becomes unstoppable.

GB/T 36558 and GB/T 36545

Two Chinese national standards for electrochemical storage on the grid: GB/T 36558 sets general technical requirements for storage systems in the power system — power control, efficiency, fault ride-through, frequency response, black start — and GB/T 36545 covers mobile, vehicle-mounted storage systems. Both were revised in 2023 and apply from July 2024.

IEC 62619

The safety standard for secondary lithium cells and batteries in industrial applications — stationary storage, forklifts, rail and marine — covering cell abuse tests plus battery-system functions such as overcharge and thermal control. It is the industrial counterpart of IEC 62133 for portable and IEC 62660 for vehicles.

LFP

A positive electrode material, LiFePO₄, giving cells a nominal voltage around 3.2 V, long cycle life and good thermal stability, but less energy per kilogram than nickel-rich oxides. Its flat voltage curve makes state of charge hard to read from voltage alone.

Stationary storage

Batteries installed in a fixed place — a container at a solar farm, a cabinet in a home — to shift energy in time or support the grid. LFP cells dominate because cost per cycle and safety matter more than mass.
