Example 1.4 It is assumed a 12-volt automotive battery is completely discharged and at some reference time t = 0, is connected to a battery charger to trickle charge it for the next 8 hours. It is also assumed that the charging rate is -1/3600 to 8e A 0st≤8 hr otherwise For this 8-hour interval compute: a. the total charge delivered to the battery b. the maximum power (in watts) absorbed by the battery c. the total energy (in joules) supplied d. the average power (in watts) absorbed by the battery
