A pack monitor measures quantities associated with the complete battery pack.

## In plain English

### What does Battery pack monitor mean?

A pack monitor measures quantities associated with the complete battery pack.

### A simple example

A system can monitor pack current and voltage in addition to measurements made at individual cells.

### What the drawings help you do

Use this block for measurements associated with the pack as a whole, such as its total voltage or current. Show any separate cell monitor explicitly. This helps the reader distinguish the pack’s overall electrical state from the individual-cell information needed elsewhere in a battery-management system.

### Before using this reference

- Name the pack-level quantities actually measured.
- Identify any separate cell-monitor connection.
- Show the data or status interface to the battery controller.

### Is a pack monitor the same as a complete BMS?

A battery-management system can include monitoring, estimation, balancing, protection and control. The pack monitor represents the specified measurements, not an automatic claim that all those other functions are included.

### Terms

- Pack: A connected battery assembly considered as a complete unit.
- BMS: A battery-management system containing the functions selected for that battery.

## How to read it

- Name the pack-level quantities actually measured.
- Identify any separate cell-monitor connection.
- Show the data or status interface to the battery controller.
- Pack-level measurement and cell-level monitoring provide different information.

## Information to show or reference

- Name the pack-level quantities actually measured.
- Identify any separate cell-monitor connection.
- Show the data or status interface to the battery controller.

## Important distinction

Pack-level measurement and cell-level monitoring provide different information.
