Battery operated computer having improved battery monitor and cell reversal protection circuit |
摘要 |
A battery operated computer includes a battery having a plurality of serially connected banks of battery cells that are monitored during operation of the computer to detect a nearly depleted battery bank and a fully depleted battery bank. The computer also includes a plurality of microprocessors including a host or system processor, a service processor and a power subsystem processor. When a nearly depleted battery bank is detected, the power subsystem processor is interrupted and it sends a message to the service processor which in turn interrupts the host processor. An interrupt handler then powers down the system. When a fully depleted battery bank is detected, the battery is immediately disconnected and the system is shutoff to prevent polarity or cell reversal.
