Embodiment Construction

[0052] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0053] like Figure 1A-Figure 6 As shown, according to one aspect of the present disclosure, a battery tray 100 and a power battery pack having the battery tray 100 are provided. In addition to the battery tray 100, the power battery pack may also include a cover plate (not shown) and a plurality of battery cells 200, the cover plate and the battery tray 100 are sealed and connected together to form a closed space for accommodating the plurality of battery cells 200 . Each battery cell 200 has a cell explosion-proof valve 201 (see Figure 1D ). The battery tray 100 includes a tray body, at least a part of the tray body is formed with a gas channel inside,...

Abstract

The invention relates to a power battery pack and a vehicle. The power battery pack comprises a battery tray and a plurality of battery single bodies arranged on the battery tray, wherein each batterysingle body is provided with a single body explosion-proof valve. The battery tray comprises a tray body, a gas channel is formed in at least one part of the tray body, a plurality of gas inlet holesand at least one exhaust hole are formed in the tray body, and the gas inlet holes and the single body explosion-proof valves are oppositely arranged and are in one-to-one correspondence. Through thetechnical scheme, once the internal air pressure of a certain battery single body is increased, the single body explosion-proof valve on the battery single body is opened, and smoke or gas in the battery single body directly enters the gas channel of the tray body through the gas inlet holes in the tray body, so that the flame, the smoke or the gas cannot enter the battery accommodating space, and the flame, the smoke or the gas is prevented from causing secondary damage to the batteries or influencing other batteries.

Description

technical field [0001] The present disclosure relates to the field of electric vehicles, and in particular, to a power battery pack and a vehicle. Background technique [0002] As an energy storage device, the power battery pack is the core component of hybrid electric vehicles and electric vehicles. The power battery pack is mainly composed of several battery cells, battery trays and cover plates. The battery tray is installed at the bottom of the vehicle, and the cover plate is sealed and connected with the battery tray to jointly form a closed space for accommodating the plurality of battery cells. In order to prevent explosion accidents, the battery cells are usually provided with an explosion-proof valve structure. During the use of the battery, if the internal air pressure increases to a certain level, the explosion-proof valve will open, and the flame, smoke or gas inside the battery cell will be discharged through the explosion-proof valve. In the prior art, after...
