Description:FIELD OF THE INVENTION
[0001] The present subject matter is related, in general to a charging of batteries, and more particularly, but not exclusively to a bi-directional USB charger for charging electronic devices and a battery of a vehicle.
BACKGROUND OF THE INVENTION
[0002] Universal Serial Bus (USB) charger is used for the charging electronic devices, such as, but not limited to, mobile phones, tablets and other smart devices supported with the USB charging protocol. Conventionally, USB charger is having either a Type A or a Type C port. Such different type of USB ports enables a wide range of mobiles and tablets for the charging.
[0003] Internal combustion vehicles usually have a kick starter which actuates the engine into starting. Such engines can also be started with an electric starter, or in modern vehicles, an ISG machine. In many IC engine vehicles, the kick starter is removed to save weight.
[0004] Currently, if a vehicle battery is low in charge, kick starter is used as a back-up to start the vehicle. This is the only function of the kick-starter, but the cost of the kick-starter is very high and additional weight of the kick starter is an issue. Thus, in recent vehicles the kick-starter is eliminated. But, in case the charge of the battery of the vehicle is less which might be because of long shelf time then the vehicle battery cannot take the necessary load for starting the vehicle, thereby creating startability issues for the rider. Additionally, if the vehicle is sitting idle for a long time, the battery gets drained and the rider has to get it recharged, which is an inconvenience. For such recharging, the battery has to be removed from the vehicle and taken to a separate battery charging service centre which is inconvenient.
[0005] One of the state of the art technology discloses about a method to charge the battery of a e-flexure vehicle with very less number of components and at the same time to travel longer distance from a single charge. The technology states that a USB connector will be connected to the vehicle battery and an adaptor will also be placed in the vehicle so that the vehicle can be charged easily.
[0006] However, for such a solution dedicated USB connector needs to be provided for the battery which increases the cost and packaging constraints of the battery. Further, using the USB connector on the battery only the vehicle battery can be charged and other devices cannot be charged.
[0007] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.
