Claim 6:
7. The battery management apparatus according to claim 2, wherein the controller is further configured to determine the first process noise and the second process noise using the following Equations 1 and 2 if the first component is lower than the first lower limit or the second component is lower than the second lower limit:

W1k=(M1D1−M2D2)+MW1  <Equation 1>

W2k=(M4D2−M3D1)+MW2  <Equation 2>

where:
D1 denotes an absolute value of a difference between the first component and the first lower limit,
D2 denotes an absolute value of a difference between the second component and the second lower limit,
MW1 denotes the first reference value,
MW2 denotes the second reference value,
M1 denotes a first weight,
M2 denotes a second weight,
M3 denotes a third weight,
M4 denotes a fourth weight,
W1k denotes the first process noise, and
W2k denotes the second process noise.
