Problems solved by technology

However, the existing battery systems of this type mostly use resistance wires to heat the battery, which has low heating efficiency and requires a long time of heating to make the battery reach the optimal working temperature. Moreover, the battery used is a large single battery, and the surface heating area of ​​this battery Small, the distance from the center of the battery to the surface is long, which also reduces the heating efficiency

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings, and the protection scope of the present invention is not limited to the following description.

[0022] Such as figure 1 and figure 2 As shown, a battery system with a heating function, which includes a plurality of cylindrical batteries 1, the two ends of the cylindrical batteries 1 are fixed on the card board 2 and connected to each other to form a battery module 3, the card board 2 passes through the card board 2 bolts are fixed. The cylindrical batteries 1 are arranged in a honeycomb structure, and gaps are left between the cylindrical batteries 1 to allow air to pass through, so that the air can fully contact the surface of the cylindrical batteries 1 .

[0023] A closed heat-insulating shell 4 containing sodium-based heat-insulating soft felt, sodium-based heat-insulating board or Ruiji heat-insulating soft felt is wrapped outside the battery module 3 to prevent...

Abstract

The invention discloses a battery system with a heating function. The battery system with the heating function comprises a battery module (3) and a heat-insulating shell (4). The heat-insulating shell is sealed, contains a heat-insulating material and covers the battery module, a heat-conducting tube (5) passing through the heat-insulating shell (4) is arranged at the bottom of the heat-insulating shell (4), a fan (6) is arranged at the bottom of the heat-insulating shell (4), an air outlet (8) of the fan (6) and the heat-conducting tube (5) are arranged face to face, at least a part of air blown out of the air outlet (8 ) is in contact with the heat-conducting tube (5) to generate heat exchange, the heat-conducting tube (5) is heated by a combustor (10), fuel of the combustor (10) is provided by a detachable fuel bottle (13), and the whole system is controlled by a controller (16). The battery system with the heating function disclosed by the invention is suitable to work at a low temperature, is convenient, safe and reliable to use, and has the advantages of low cost and high heating efficiency.

Description

technical field [0001] The invention relates to a battery system, in particular to a battery system with a heating function. Background technique [0002] With the continuous development of battery technology, more and more battery products are applied to various fields, providing us with convenient and clean energy. The battery is the core power supply component, and the performance of the battery is directly related to the working stability of the entire system. When working under low temperature conditions, the temperature characteristics of the battery are very important. The temperature characteristics of ordinary batteries are not ideal, and low temperature will lead to a significant deterioration of battery performance. In order to meet the requirements of batteries working under low temperature conditions, it is often necessary to use special materials to make special low temperature batteries, which is not only expensive, but also has very limited improvement in lo...
