<p>The present invention is directed to a measurement system for measuring a series connection of energy storage devices comprising: a. a number of energy storage devices (C(1)...C(N)) in a series connection, b. a differential amplifier having a first input A and a second input B for coupling it over an individual storage device or over a section of the series connection comprising a plurality of said storage devices, said individual storage device or said section of the series connection having a more negative terminal and a more positive terminal, c. a network of switching means for connecting said more negative terminal to said differential amplifier's input A, and said more positive terminal to said differential amplifier's input B, or vice versa. Further, the present invention is directed to an assembly comprising a series connection of energy storage devices and a measurement system as described above. Additionally, the present invention is directed to method for measuring a series connection of energy storage devices comprising the steps of: a. providing a number of energy storage devices (C(1)...C(N)) in a series connection, b. providing a differential amplifier having a first input A and a second input B, c. selecting one individual energy storage device or a section of the series connection comprising a plurality of energy storage devices, said individual storage device or said section of the series connection having a more negative terminal and a more positive terminal, d. connecting said more negative terminal to said differential amplifier's input A, and said more positive terminal to said differential amplifier's input B, or vice versa. Additionally, the present invention is directed to the use of such system and method for measuring a series connection of electric double-layer capacitors, lead acid or NiMH batteries, lithium energy storage devices or Li-ion energy storage devices.</p> |
