Lightning is still electricity. It technically follows _all_ the paths, but most of the current will go through the low-resistance paths. For the battery to explode, the lightning will need to cause a potential difference across its terminals. But why would it? The paths _around_ the battery cells (through the battery and car body) have much less resistance. The conductors in the charging cable can melt, because the path from the car, though the cable, and through the EVSE body to the ground is another relatively low-resistance path.
