Short Circuit Load Conditions

The load is implemented as an integrating circuit. This means that it can be used to simulate high out-rush currents: if the load is enabled, but no current source is available, it will saturate and open fully (max load). When a voltage/current source is enabled the load will for a short moment draw maximum current, and can be seen as a short circuit load. As soon as the current starts flowing the load will start to adjust the current to reach the target level.

This can cause problems if one is not aware of this, since the smart battery AVR MCU will detect this event as a high current/over current/short circuit situation. However, this characteristic of the load can be used to test an implementation of a smart battery, as it can be used intentionally to trigger a high out-rush current situation and validate correct behavior.
