Battery monitoring system for a vehicle and a method thereof
First Claim
1. A battery source monitoring system for a vehicle, the system comprising:
- a plurality of switching circuits, each switching circuit with a two-way current line to enable switching of one or more accessory devices between a primary battery source and an auxiliary battery source;
at least one current sensor configured to detect current consumption of the one or more accessory devices connected to an auxiliary battery source; and
a control unit, interfaced to the plurality of switching circuits, the primary battery source, the auxiliary battery source, the at least one current sensor and an ignition sensor, on detecting vehicle ignition OFF condition, is configured to;
determine ON condition of the one or more accessory devices;
switch power source of the one or more accessory devices in ON condition from the primary battery source to the auxiliary battery source;
comparing current consumption of each accessory device with a predetermined threshold; and
when the current consumption of a first accessory device surpasses the predetermined threshold, control the plurality of switching circuits to;
disconnect the first accessory device from the auxiliary battery source by switching power source of the first accessory device from the auxiliary battery source to the primary battery source; and
selectively power the remaining accessory devices and the at least one current sensor by the auxiliary battery source simultaneously, thereby monitoring the battery source of the vehicle.

Abstract
The present disclosure discloses a battery source monitoring system for a vehicle. The system comprises at least one current sensor configured to detect current flow from one or more accessory devices connected to an auxiliary battery source. The control unit on detecting vehicle ignition OFF condition, is configured to determine ON condition of one or more accessory devices and switch power source of the one or more accessory devices in ON condition from primary battery source to auxiliary battery source. The control unit then compares current flow received from current sensor with a predetermined threshold. When current flow detected by current sensor surpasses predetermined threshold, the control unit disconnects one or more accessory devices from auxiliary battery source and primary battery source, and switch power source of one or more accessory devices from auxiliary battery source to the primary battery source, thereby monitoring battery source of vehicle.
