Gerade im ES-Forum drüber gestolpert:

Klingt vielversprechend, aber noch ist der Chip nicht in Serienproduktion, und für nähere Infos muß man eine Geheimhaltungsvereinbarung unterzeichnen .Linear Technology is currently developing a complete multi-cell battery measuring IC, capable of monitoring up to 12 individual cell voltages. Using a novel stacking technique, multiple monitor ICs can be placed in series without opto-couplers or isolators, allowing multi-cell strings greater than 1000 volts to be monitored. The Multi-Cell Battery Stack Monitor IC includes an ADC and a precision voltage reference, allowing very accurate and quick voltage measurements of each individual cell. In addition, each cell can be discharged using on-board switches for cell balancing (avoiding over-charge conditions).
