Copper Busbar and Nickle Strip Calculation for Battery Pack. We are first year EV team and I have been assigned to do all battery pack related calculation. Copper Busbar Calculation.... Busbar size in sqmm = Max battery current/cu. current carrying capacity Nickle Strip calculationfor nickel strip calculation i used a ampacity chart link below
The width and material of the nickel strip should be selected according to the current of the lithium battery pack. In terms of material, there are two commonly used nickel strips: pure nickel strips and nickel plated steel. What is the difference between their performance and actual use?
If each battery cell in parallel had its own 15A nickel strip connection to the next battery in series, you'd have 5 independent 12v batteries that arerated for 15A and are properly sized, adding a strip between them allows them to compensate for minor differences in voltage and capacity while also naturally balancing the 5 12v batteries together.
In routine use, the calculation formula is: pure nickel strip calculates the overcurrent capability according to 10A/mm², such as pure nickel with a thickness of 0.15mm*7mm wide, its maximum continuous overcurrent recommendation is 10*0.15*7=10.5A;
For nickel-plated steel, its calculation formula is usually calculated according to 7A/mm², that is to say, the maximum continuous overcurrent of nickel-plated steel with a thickness of 0.15mm*7mm is 7*0.15*7=7.35A. It can be seen that the current that a pure nickel strip can withstand is about 1.5 times that of nickel plated steel.
Once the nickel strip melt through the plastic covers of the cells and bridge the positive end to the negative casing (which comes very close to the positive), your battery will short and become a bomb. Personally, I see every Watt of power lost in heat as less power injected in the motor...
