I had a feeling that the batteries were limiting the performance of the motor because they couldn't deliver that much current. Batteries are normally rated in Ampere-hours (Ah), not in Amperes. An Ampere-hour is a measure of the energy stored in the battery, and is not directly related to the current that the battery can deliver.
If there isn't enough current and you add a battery, you can expect increase in torque because the voltage supplied by the batteries will be higher. This was a fantastic answer. Thank you for correcting my misconception -- I did not know that the resistance of a motor is constant.
This paper documents an experimental investigation that studies the long-term impact of current ripple on battery performance degradation. Initial results highlight that both capacity fade and impedance rise progressively increase as the frequency of the superimposed AC current increases.
The test results demonstrate that high-power charging significantly impacts the durability and thermal safety of the high-capacity lithium batteries. In particular, the capacity fading rate can reach up to 30% only after 100 charge cycles depending on the battery type.
This applies in particular for EV batteries with an expected lifetime of more than ten years. This study investigates the influence of alternating current (ac) profiles on the lifetime of lithium-ion batteries. High-energy battery cells were tested for more than 1500 equivalent full cycles to practically check the influence of current ripples.
Exceeding the rated current of a battery can lead to several issues. The battery is likely to heat up more due to the increased power loss through internal resistance, which is proportional to the square of the current.
The fact that it takes longer to charge must mean that the battery is pulling less current and thus also heating less. In battery terminology, the charger is what takes an input power source and …
