4 FAQs about Maximum charging and discharging power of energy storage equipment

What is energy storage duration?

When we talk about energy storage duration, we’re referring to the time it takes to charge or discharge a unit at maximum power. Let’s break it down: Battery Energy Storage Systems (BESS): Lithium-ion BESS typically have a duration of 1–4 hours. This means they can provide energy services at their maximum power capacity for that timeframe.

What is the difference between rated power capacity and storage duration?

Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.

How do battery energy storage systems help EV charging?

Battery energy storage systems can enable EV fast charging build-out in areas with limited power grid capacity, reduce charging and utility costs through peak shaving, and boost energy storage capacity to allow for EV charging in the event of a power grid disruption or outage.

How long does a battery energy storage system last?

Let’s break it down: Battery Energy Storage Systems (BESS): Lithium-ion BESS typically have a duration of 1–4 hours. This means they can provide energy services at their maximum power capacity for that timeframe. Pumped Hydro Storage: In contrast, technologies like pumped hydro can store energy for up to 10 hours.
