"textContent": "A protection system for a high-voltage component includes a switching circuit and a protection controller. The switching circuit changes a variable arrangement of multiple battery packs between a parallel arrangement and a series arrangement. The protection controller commands the switching circuit into the series arrangement in response to a recharging session, commands a current flow in the recharging session, measures a measured voltage between an input node and a floating chassis ground of the high-voltage component, advances a timer while the measured voltage indicates a presence of an improper voltage, and cancels the recharging session in response to the presence of the improper voltage for greater than an exposure time. The recharging session provides a direct-current fast-charging voltage to battery packs in the series arrangement, and is greater than the battery voltage.",
