One of the most important uses of nickel-metal hydride batteries is the use in hybrid cars. This thesis attempts to examine the sudden rise in temperature due to fires, vibration caused by road crashes, and physical deformation caused by accidents. Each of these events involved a battery designed to simulate conditions and obtain test results. One battery was also used as a standard sample to compare the results of other batteries with this one. The general way of testing is that the first three charge-discharge cycles were applied to all batteries. Then the internal resistance and open circuit voltage of each battery were measured. Now each of the batteries (except the standard sample) was subjected to what was happening. Then the internal resistance and open circuit voltage were again measured for all the batteries. Then the three charge-discharge cycles were applied to all the batteries, and the electrochemical impedance spectra were taken and the same process was repeated. According to the results, the battery can withstand temperatures up to 140 degrees Celsius and is reusable, with its internal resistance varying by 6 millimeters and 0.1V open circuit voltage. Vibration up to 8 Hz has a positive effect on battery performance, as the resistance and voltage of the open circuit of the battery is unchanged. Also, the discharge capacities of this battery showed a lower discharge capacity compared to standard battery and during 60 charge-discharge cycles, standard battery of 8.6% and vibrated battery of 5.6%. Therefore, vibration will increase the useful life of the battery. Also, damage to the battery caused by physical deformation of up to 15% does not cause such batteries to fail, such that in 15% of the physical deformations the voltage drop is 0.1 V and A 3 mmHg increase in resistance was observed.
