Vehicle battery management system and method
First Claim
1. A battery management system for a vehicle, comprising:
- a battery;
a battery sensor for measuring a condition of said battery; and
an electronic control unit receiving a signal from said battery sensor corresponding to said condition of said battery, said electronic control unit configured to selectively and independently connect and disconnect the battery to and from each of at least one accessory load and at least one other load, wherein when the vehicle is in an accessory ON mode and in a shipping mode, said electronic control unit connects said at least one accessory load to said battery and disconnects said at least one other load from said battery, and wherein when the vehicle is in said accessory ON mode, in said shipping mode and said signal indicates that said condition of said battery is below a predetermined threshold, said electronic control unit disconnects said at least one accessory load from said battery.

Abstract
A vehicle battery management system and method includes a battery, a battery sensor for measuring a condition of the battery and an electronic control unit that receives a signal from the battery sensor corresponding to the condition of the battery. The electronic control unit selectively connects and disconnects that the battery from each of: at least one accessory load and at least one other load. The at least one other load is disconnected from the battery when the vehicle is in a shipping mode and the at least one accessory load is connected to the battery when the vehicle is in an accessory ON mode. The electronic control unit disconnects the at least one accessory load from the battery when the vehicle is in the accessory ON mode and in the shipping mode when the signal indicates that the condition of the battery is below a predetermined threshold.
