Hibernium® battery systems use a liquid thermal management system to regulate the battery cell temperature, ensuring safety and high performance. An appropriate Vehicle Thermal Management System needs to be implemented to enable safe operation in specified conditions. Please refer to the specific battery configuration datasheet for information about required heat rejection capacity, flow rate, and pressure drop.
A water-glycol mixture (50/50) is the recommended thermal management medium to use with Hibernium® battery systems. Deviation from the recommendation will result in reduced thermal performance and potential battery pack damage.
The gauge pressure (difference between the internal and the external/ambient pressure) at the inlet to the battery pack shall not exceed 1.0 bar. A hard mechanical limit of 1.5 bar shall be set through the placement of a pressure relief valve before the inlet port of the battery pack. The battery pack inlet port shall not be positioned directly adjacent to the outlet of the pump to avoid sudden pressure spikes from the pump being directly transmitted to the battery pack. The pump itself shall not have a shut-off head exceeding 1.0 bar.
Ambient pressure will vary according to elevation with respect to sea level; therefore, the coolant expansion tank shall be vented to ambient to help ensure that the gauge pressure never exceeds 1.0 bar.
