How are the battery pack design and cost calculated in Batpac?

The battery pack design and cost calculated in BatPaC represent projections of a 2020 production year and a specified level of annual battery production, 10,000-500,000. As the goal is to predict the future cost of manufacturing batteries, a mature manufacturing process is assumed.

What are the thermal runaway propagation characteristics of a commercial battery pack?

The thermal runaway propagation characteristics of a commercial battery pack system was revealed. Temperature, voltage, gas and pressure during the thermal runaway propagation were analyzed. The thermal runaway propagation model of the battery pack was established. The model well predicts the thermal runaway spreading trend between modules.

What is the best thermal management method for EV battery packs?

Traditional thermal management methods such as forced air cooling and direct/indirect liquid cooling have been extensively investigated and adopted on commercial EVs for their power battery packs in recent years.

How does a battery test work?

The battery pack being tested will be fully charged in advance to simulate the most severe thermal runaway scenario, ensuring that the battery has maximum energy during testing. The specific method involves charging to 4.2 V with constant current and voltage, and calibrating it to 100% state of charge (SOC).

What happened during battery thermal runaway test?

During the battery Thermal runaway test, the temperature sensor inside the battery module was damaged, so the battery temperature date recorded of Battery Thermal runaway test disappeared after about 200 s.
