Claim 10:
11. An electrical battery, comprising:
a plurality of battery cells;
a monitoring device comprising:
a first group of electrical sensing switches connected in series a first monitoring circuit, said sensing switches being adapted to switch between a first state and a second state depending on at least one parameter of at least one battery cell of the battery;
a second group of electrical sensing switches connected in series to a second monitoring circuit, said sensing switches are configured to switch between a first state and a second state depending on at least one parameter of at least one battery cell of the battery, the second monitoring circuit being electrically isolated from the first monitoring circuit;
an input unit connected to the first monitoring circuit at a first input point and to the second monitoring circuit at a second input point, said first input point being adapted to provide an electrical input to the first monitoring circuit and to the second monitoring circuit;
a monitoring unit adapted to receive at least one electrical output from the first monitoring circuit and at least one electrical output from the second monitoring circuit;, wherein
the first monitoring circuit comprises at least two measuring points connected to the monitoring unit;
the monitoring unit is configured to receive at least two electrical outputs from the at least two measuring points of the first monitoring circuit;
the at least two measuring points are separated by at least one sensing switch of the first group of electrical sensing switches.
