Specification

Description:FIELD OF THE INVENTION
[001] The present invention relates to a battery pack. More particularly, the present invention relates to a grommet for a cover of the battery pack.

BACKGROUND OF THE INVENTION
[002] Battery packs are the most commonly used energy devices having vast applications in various fields ranging from general devices to electric vehicles. The battery packs supply power to an electric motor to drive the electric vehicles such as electric cars or electric bikes etc. Depending upon the usage or requirements, the battery pack houses a plurality of high-capacity batteries to produce high output voltage and current. The plurality of high capacity batteries collectively function to increase output power, or more specifically increases the battery discharging power supplied to the electric vehicle.
[003] In existing configuration, the battery pack includes a case and a cover provided with connector(s) arrangement. The case of the battery includes a structure that allows it to be stored in a removable manner with respect to the electric vehicle. When the battery pack is stored inside the electric vehicle, the structure of the battery pack enables electrical connection of the connectors with battery terminals. The connectors are further connected to power adapters or power receiving electrical terminals for providing power to the electric vehicle. It has been observed that a high amount of the discharge current flows through the connector to the connecting terminals.
[004] It has been observed that electric vehicles are generally used under conditions that generate vibrations. It is essential to effectively prevent connector to connecting battery terminal contact resistance malfunction which occurs due to vibrations. Such contact resistance malfunction can be effectively prevented by a structure that connects the connector and the battery terminals. Accordingly, a reliable electrical connection between the connector and the connecting terminals is required, and specifically a low resistance connection. As a solution, grommets were proposed to be used to hold the battery terminals being in connection with the connector. However, the existing grommets were observed to fail in effectively holding the battery terminals at their original positions while the vehicle is in running condition and vibrations are produced thereof. Due to which said battery terminals dislocate away from the connector and may contact each other or surrounding parts or components of the battery pack thereby increasing the risks of short-circuiting which may lead to a serious safety hazard.
[005] It has also been observed that due to space constraints and compactness requirements of the battery packs, the existing grommets are more prone to fitment issues which increases the assembling complexities and also the sealing issues in preventing the dust, water, and moisture entry. The existing grommets also face issues in locating or routing the wires or CAN communication cables which are to be connected to components outside the battery pack.
[006] It has also been observed that during assembling there can be high chances of short circuit if the technician is not careful while assembling the battery pack and connecting the battery terminals with connectors owing to factors of the proximity between the connector and battery terminals including the condition of battery terminals being very close to the cover made of metal such as aluminum.
