This application discloses a battery pack, relating to the field of battery technology. The battery pack includes a support frame, several battery cells, a current collector assembly, and a side plate. The support frame, current collector assembly, and side plate enclose a receiving space, and several battery cells are stacked and arranged in the receiving space along a first direction. Each battery cell includes interconnected terminals and a body. The terminals and explosion-proof valves are located on different sides of the body. The side plate is located on the side of the body where the explosion-proof valves are located, and the exhaust channels in the side plate are configured to communicate with each explosion-proof valve. The current collector assembly is located on the side of the battery cell where the terminals are located and is electrically connected to the terminals of each battery cell. This separates the electrical connection of the battery cells from the exhaust channels, achieving thermoelectric separation and preventing high-temperature, high-pressure gas from flowing out of the explosion-proof valves and affecting electrical components, thus improving the safety of the battery pack. In addition, compared with related technologies, this application saves installation space and reduces the weight of the entire battery pack while satisfying basic electrical connection functions.

The utility model provides a high-voltage connecting rod and ignition coil, high-voltage connecting rod includes rod body and install the waterproof ventilation piece on the rod body, the rod body is provided with first channel and second channel, the one end of first channel is used for being communicated with spark plug installation well, waterproof ventilation piece is located between second channel and first channel. The end, communicated with the first channel, of the second channel is a first end, the end, communicated with the outside of the ignition coil, of the second channel is a second end, and the second end is not higher than the first end in the axial direction of the high-voltage connecting rod. The first channel and the second channel are arranged in the high-pressure connecting rod, and the waterproof breathable piece is arranged between the first channel and the second channel, so that the high-pressure connecting rod not only has a splash-proof function, but also can quickly discharge accumulated water on the waterproof breathable film through the second channel under the extreme working conditions that a vehicle wades in water and an engine is submerged by water, and the service life of the high-pressure connecting rod is prolonged. Water is prevented from accumulating on the waterproof breathable film, so that the durability of the waterproof breathable film is not influenced.
