Customer ServiceRecent results indicate that a new type of abuse condition, electrochemical abuse, is the underlying mechanism for the emerging causes of battery failure, as shown in Figure 2.
Battery pack testing comprised of testing battery packs individually as well as their integration into the working string of batteries to simulate the actual energy storage system on-board an eBus. The battery pack was tested on charge and discharge for a period of 6 hours at a range of current capacities up to 25 A.
Compactness of packaging design also has an appreciable impact on thermal performance of the battery pack. Research shows that increasing the cell-to-cell spacing for a battery pack from 1 to 10 mm can lead to a loss of approximately 1 °C in the steady-state cell core temperature, for all the three physical formats .
At the pack level, the failure propagation causes problems because it may be necessary to deal with fires caused by several cells. Preventing failure propagation is important for the safety design of lithium-ion battery packs.
The acceleration and top speed of an EV mostly depend on the motor. However, it is the battery pack that holds importance. The battery pack limits the performance of EVs and is prone to failure. The battery pack is prone to thermal runaway (TR), which can cause fire and explosions.
In addition to lithium-induced battery failure, the cycle life is another problem. For instance, the use of lithium as an anode causes dendrite growth and pulverization during cycling, thereby significantly reducing the life of the cell. The large volume change in a cell with a lithium anode is also an unsolved problem.
