Description

TITLE OF INVENTION
A PROTECTIVE CAP FOR A BATTERY CONNECTOR OF A VEHICLE
FIELD OF THE INVENTION
[001] The present invention relates to battery connectors of a vehicle. More particularly, the present invention relates to a protective cap for a battery connector of the vehicle.
BACKGROUND OF THE INVENTION
[002] Electric vehicles (EVs) as well as the hybrid vehicles have gained significant popularity and high demands due to their environmental benefits and cost-effectiveness. In hybrid vehicles, apart from the internal combustion usages, an electric propulsion system with additional batteries is provided to drive the vehicle in predefined conditions. The electric vehicles are powered by one or more batteries, to provide the necessary energy for propulsion whereas the number of batteries depends upon the power requirements and configuration of the vehicle. With the advent in renewable technologies, battery systems were developed to introduce the provision of removable rechargeable batteries which can be replaced and/or used in conjunction with other charged batteries, if required. The removed battery can also be charged separately from the vehicle while the vehicle may run on another battery. Such batteries are designed to be easily removable, allowing for convenient replacement or recharging.
[003] In existing configuration of vehicles, removable batteries are connected to each other through battery connectors. Battery connectors electrically connect terminals of one battery with terminals of another battery through power terminals. While removing or replacing batteries, the battery connector of one battery is required to be detached from another battery connector. It has been observed that when one of the batteries is removed from the electrical vehicle, the power terminals of the remaining battery connectors are exposed and pose safety concerns.
[004] Moreover, the electric vehicles are designed and manufactured with multiple variants possessing different configurations in specifications of battery storage as well as the traction power. Some variants of the vehicles and especially, the lower variants are assembled with lesser number of batteries as compared to higher variants of the same vehicle. Due to mass manufacturing, the general configuration of the battery storage and battery connectors remains the same to avoid additional costs and reduce assembly time and due to which a storage space for additional battery is left vacant and the power terminals of the battery connectors are left open or exposed in lying condition inside the battery storage space. In such situations, a battery current from the available and/or stored battery keeps flowing through the exposed power terminals and an accident contact with these power terminals can lead to short circuits, or other hazards.
[005] Further, it has also been observed that in vehicles whereas the battery storage compartment is adjacent and/or being used or shared commonly with utility storage compartment, the exposed power terminals of the battery connectors may contact stored metal objects, articles therein and thus are susceptible to cause damage to the articles or the components of the battery system and including the vehicle itself. Furthermore, when the power terminals of the battery connector are in open condition, dust and/or water particles enters and accumulates inside the battery connector which leads to power terminal corrosion and causes further damage to the battery connector as well as the battery.
[006] In view of the foregoing, there is a need to provide a protective cap for protecting a battery connector which solve at least one of the aforesaid problems.
