An energy storage type new energy battery protection system and method for smart energy network

Abstract

The invention discloses an energy storage type new energy battery protection system used for an intelligent energy net and a method of the energy storage type new energy battery protection system. The system consists of a battery pack, a shell, a polyhydric alcohol phase change material, a fatty acid phase change material capsule and a fiber material fin. The solid-phase polyhydric alcohol phase change material is used to absorb heat and melt, so as to restrain the sharp temperature increment of the battery pack within a short time, the solidification of a liquid phase fatty acid phase change material in the fatty acid phase change material capsule is used to preserve heat of the battery pack, and the characteristic that a heat conductivity coefficient of the fiber material fin is increased along with temperature increment is used to further realize functions of improving heat dissipation under high temperature and enhancing freeze prevention under low temperature for the battery pack; the polyhydric alcohol phase change material absorbs heat, stores energy and supplies the heat to users, and is energy-saving, economical and environmentally friendly; the system is high in adaptation, and can be used in an extreme environment with great temperature difference change; the phase change materials are good in repeatability, and the service life is long.

Description

technical field [0001] The invention relates to the field of smart energy network and new energy, in particular to an energy storage type new energy battery protection system and a method thereof for the smart energy network. Background technique [0002] With the increase of environmental pressure, the limited nature of conventional energy has become increasingly prominent, and the new energy with environmental protection and renewable advantages has attracted more and more attention from the world. The development of the new energy industry can not only effectively supplement the supply of the entire energy system, but also benefit the governance of the ecological environment. It is the best choice for the sustainable development path in the future. [0003] The smart energy network integrates various renewable energy sources such as solar energy, geothermal energy, water energy, air energy, and industrial wastewater waste heat. It takes the balance of cold and heat as the...
