Problems solved by technology

The higher the temperature of the battery, the greater the heating effect, the greater the risk of thermal runaway in the battery, and the greater the possibility of the battery catching fire and exploding. Once the battery explodes, it will seriously threaten the safety of people's lives and bring property. In addition, as the temperature of the battery increases, the capacity and life of the battery will be damaged more; therefore, how to accurately monitor the battery temperature and respond quickly when the battery temperature is too high has become an urgent need
[0003] At present, most of the existing battery temperature control starts from the outside of the battery. However, the monitoring of the external temperature control is not accurate to a certain extent, and the error with the internal temperature of the battery is large. The response is not fully in line with the actual situation of the battery, there are some misunderstandings

Abstract

The invention discloses a battery having a cooling effect. The battery comprises a battery main body, a protective sleeve sleeves the battery main body, an enclosed space is formed between the protective sleeve and the battery main body, the protective sleeve is provided with a communication opening, a cooling and storage tank is installed at the communication opening, a cooling and fire extinction substance is stored in the cooling and storage tank, an enclosed device is installed at the communication opening, the enclosed device comprises a baffle plate, a spring, an electromagnet and a thermobattery, the baffle plate covers the communication opening and is slidingly connected to the protective sleeve, one end of the baffle plate is prepared from a magnetic conductive material, the end or opposite end is provided with the spring, two ends of the spring are respectively connected to the baffle plate and the protective sleeve, the electromagnet is located in one end of the baffle plate prepared from the magnetic conductive material, the electromagnet is connected to the thermobattery, a hot end of the thermobattery is arranged in the enclosed space or on the battery main body, and a cold end of the thermobattery is located outside the protective sleeve. The battery improves the interior of the existing battery and utilizes the temperature in the battery to cool and drive.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery with cooling effect. Background technique [0002] In recent years, with the rapid development and application of batteries, the safety and stability of batteries have received widespread attention, and one of the main factors affecting battery safety and stability is temperature. The higher the temperature of the battery, the greater the heating effect, the greater the risk of thermal runaway in the battery, and the greater the possibility of the battery catching fire and exploding. Once the battery explodes, it will seriously threaten the safety of people's lives and bring property. In addition, as the temperature of the battery increases, the capacity and life of the battery will be damaged more; therefore, how to accurately monitor the battery temperature and respond quickly when the battery temperature is too high has become an urgent need. [0003] At present, ...
