Power density refers to the power that can be output per unit volume or per unit mass, measuring the speed at which batteries or electrical power systems release or absorb energy. It is a key indicator for evaluating the performance of batteries in high-load scenarios (such as electric vehicle acceleration, frequency regulation, etc.).
Engineering significance and design considerations
High power density batteries can achieve faster charging and discharging rates, and rapid response capabilities;
They are suitable for applications such as electric vehicle acceleration, grid frequency regulation, heavy load starting, and BESS frequency control;
When designing energy storage systems or battery packs, a balance must be struck between power density and energy density.
