Abstract:
1. In a vehicle having an ignition system for selectively starting and stopping an engine of the vehicle and an electrical system including an electrical load and a battery, a battery protection system connected to the vehicle ignition system comprising: a first device connected between the battery and the load to protect the load from receiving excessive current; a second device connected in series with the first device, the second device having a closed state and an open state to selectively connect and disconnect respectively the load to and from the battery; and a counter connected to the ignition system to count a number of ignition cycles; and a controller connected to said second device to thereby control the operation of the second device in response to the number of ignition cycles from the controller, the controller having a first threshold number store therein, wherein the controller obtains the number of ignition cycles from the counter and compares the number of ignition cycles to the first threshold number, and wherein the controller controls the second device to operate in the closed state to connect the battery to the load until the number of ignition cycles is greater than the first threshold number.
