Second life employment of a traction battery for load match optimisation of a residential building: Life cycle and operation applications

The increasing use of renewable energy technologies for the electricity generation in buildings will require a growing number of energy storage systems (ESSs) in the next years in order to reduce the mismatch between the highly variable on-site electricity generation and the building load. Retired electric vehicle batteries (EVBs), before recycling, can be used for this purpose, considering that they have about 80% of the original energy capacity. In this context, the study aims at examining an ESS made by retired EVBs, in order to identify its optimal size for reducing the mismatch in a net zero energy building equipped with a photovoltaic plant and to assess the life cycle energy and envi…

Reuse of electric vehicle batteries in buildings: An integrated load match analysis and life cycle assessment approach

Abstract The increasing use of renewable energy technologies for electricity generation in buildings will require a growing number of battery energy storage systems (BESS) to enhance the reliability of electricity supply. The increasing number of retired electric vehicle (EV) batteries, expected from the automotive sector, can match this demand as EV batteries can be used as BESS, considering that they have about 80% of their original energy capacity. In this context, the study aims at examining the system, consisting of a BESS made by retired Li-ion EV batteries, a photovoltaic plant (20 kW) and the electricity grid, that provides the electricity required by an existing nearly net zero res…

DEMAND Project: A Peak Load Shaving Strategy for End-User Consumers

2018

Battery energy storage systems (BESS) are becoming increasingly widespread in modern power systems, thanks to the important benefits they can provide to the electricity grid. Indeed, BESS can be used in time shifting applications, storing energy during off-peak periods and discharging during peak times (when the cost of electricity is high). When BESS are used for peak shaving purposes, they also contribute to relieve peak demand charges, thus ensuring a saving for the consumers. This paper describes a peak load shaving strategy defined within the DEMAND project. The strategy is able to guarantee the flattest daily power diagram and the maximum benefit for the electricity consumers, reducin…
