When integrating the Evolion in the application make sure to avoid obstructing all of the vent ports.
It is recommended to discuss venting strategy with your Saft representative in order to conclude on the need to implement venting
channels and suppression systems. See more details in the chapter Cell Venting in operation.
The Evolion is a sealed battery system. In normal operation the module never releases any gas.
The cells are designed to open and vent if a maximum internal cell pressure is ever encountered. In the controlled venting process,
the cell’s internal pressure will equilibrate with the atmosphere permitting the release of the cell gas. The module is designed with
channels and vent ports in order to allow the gas to escape from the module. See figure below.

8.4 Heat sink dissipation in charge regulated mode
When charge regulated mode is active, the heat sink on the front face dissipates the excess charge energy when the re-charge current
decreases to approximately 4 Amps.
The generated heat is a function of the module temperature. The following table summarizes heat dissipated to the environment from
the heat sink when the network voltage is set at 56.0 Vdc charge level.
