2.2 The capability of BMS
It's time to put this battery's BMS to the test with our maximum charge and discharge rate test. This test will assess the battery's overvoltage resistance. tested by drawing as much current as possible from the battery is extracted before it switches off.
We will also closely monitor the battery temperature to ensure it can handle high starting loads without overheating or being damaged. Using a BMS rated for 100 amps, we will push the limits of what this battery can handle to see how it performs under stress.
But what about longer runtimes? To assess this, we need to conduct further tests to determine how long the battery can withstand a high load before reaching its minimum voltage threshold.
Stage 1: Draw a load of 300 amps
To evaluate the extended runtime of this battery, we are conducting another test. We will begin by subjecting the battery to a 300-amp load and observing its performance over time.If it can withstand this load without shutting down, we will further increase the time and gradually decrease the load until we find the maximum load that the battery can withstand for five minutes without shutting down.
This test will give us a better idea of how well the battery performs under sustained high load, which is crucial for applications such as operating air conditioners or other high-performance devices.
We will monitor the battery temperature We will monitor the battery closely during this test to ensure it does not overheat or become damaged. With these precautions, we are confident that we can achieve the extended battery life. to be able to assess accurately.
So stay tuned as we put this battery through its paces and find out how much load it can handle over an extended period.
Our long-term test is complete, and the results are in. During the test, we initially subjected the battery to a 300-amp load and observed its behavior over time.
After about 1 minute and 11 seconds, the battery switched off. due to overheating. The BMS switched on and disconnected the battery. It shut down completely until it cooled down to a safe level. After a waiting period of almost 5 minutes, the battery... Back online at 13.3V.
Stage 2: Ea load of 200 amps pull
To further evaluate the extended runtime of this battery, we are conducting another test. This time, we will start by subjecting the battery to a 200-amp load and see if it can withstand this load for five minutes without shutting down.
By using the battery Testing under a lower load will give us a better idea of its endurance in real-world applications where sustained performance is required. We will monitor the battery's power output and temperature. Monitor closely during the test to ensure its safety and reliability.
So stay tuned as we put this battery through another round of testing to see how well it can handle a continuous load of 200 amps over an extended period.
After 2 minutes and 21 seconds, the BMS overheated, causing the battery to shut down. This led to [unclear - possibly a result]. However, the temperatures we measured during the test were all within a reasonable range for an overheated battery. The temperature in the center of the battery was 81.1°F, at the top of the battery 78°F, at the positive terminals 108.4°F, and at the negative terminals 111.2°F.
Overall, the battery was unable to withstand a 200-amp load for five minutes without shutting down, but its temperatures remained within safe limits during the test. This suggests that this battery may be better suited for applications requiring high pulse loads rather than continuous loads over extended periods.
Stage 3: Ea load of 150 amps pull
To further evaluate the extended runtime of this battery, we will conduct another test with a lower load. This time, we will subject the battery to a 150-amp load and see how long it can withstand this load without shutting down.
