BQ77908电池保护

Other Parts Discussed in Thread: BQ34Z100, BQ34Z100EVM, BQ77910A, BQ77PL900

(1)我想使用BQ34Z100检测16串电池组的电池容量(总电压已经超过50V),但是在PDF“bq34z100EVM Wide Range Impedance Track™ Enabled Battery Fuel Gauge Solution”第4页3.3的第一段描述中发现如下描述“While the bq34z100 firmware is able to handle battery voltage up to 65 V, voltages above 50 V should never be applied to the EVM.”请问怎样才能直接监测总电压超过50V的电池组?

(2)我想用两片BQ77908保护16节电池单体,但是16节电池单体串联起来之后的最高电压已经超过了单个芯片的电源电压?请问应该怎么做,能否给我一些两片芯片保护16节电池组的参考电路图。邮箱:hjkahala@163.com.

谢谢
