Multifunctional insulating barrier structure for power battery

Abstract

The invention discloses a multifunctional insulating barrier structure for a power battery. Each insulating barrier (1) is arranged between two batteries (2) which are in cross distribution in a power-battery system, and the inner surface of each side-edge limiting strip (3) is connected with the insulating barrier (1); the top of each side-edge limiting strip (3) is provided with a wire limiting slot (4), and the bottom is provided with a foot (5); a plurality of grids are vertically distributed on the surface of each insulating barrier (1); heat dissipating channels (7) are arranged among the grids; one of the grids is marked as the grid I (6), and the other grids are marked as the grids II (8); the top and the bottom of the grid I (6) are respectively provided with a temperature-probe limiting device and a lower limiting block (9); and the top and the bottom of each grid II (8) are respectively provided with an upper limiting block (10) and a lower limiting block (9).

Description

technical field [0001] The invention relates to a multifunctional insulating barrier structure for a power battery. Background technique [0002] At present, because the power supply system is mainly used in pure electric or hybrid city buses or buses, and the working environment is relatively harsh, the safety requirements for battery packs are very high. The heat of the power battery cannot be taken away quickly during use, which will cause heat to accumulate in the battery box, and the temperature will gradually rise, resulting in battery failure or even the risk of fire and explosion. Therefore, it is necessary to ensure the ventilation and heat dissipation of the battery, and to accurately detect each The temperature of a temperature control point. The power supply system will fall off due to vibration, sharp turns and other conditions in harsh working conditions, which will affect the safety of the power supply system. Therefore, it must be ensured that the power batt...

The heat of the power battery cannot be taken away quickly during use, which will cause heat to accumulate in the battery box, and the temperature will gradually rise, resulting in battery failure or even the risk of fire and explosion. Therefore, it is necessary to ensure the ventilation and heat dissipation of the battery, and to accurately detect each The temperature of a temperature control point

The power supply system will cause the battery to fall off due to vibration, sharp turns, etc. in harsh working conditions, which will affect the safety of the power supply system. Therefore, it must be ensured that the power battery will not move during use.
