The subject matter described herein relates to a battery pack (400) comprising a retrofit PCM filling unit (411) for filling phase change material (PCM) into the interior of the battery pack (400). The retrofit PCM filling unit (411) includes a lid (401), a funnel (404), and a gasket (403). The cover (401) is placed on a top cover (405) of the battery pack (400). The gasket (403) is disposed between the cover (401) and the funnel (404), and the funnel (404) is inserted into the PCM filling port (406) of the battery pack (400). The present subject matter provides an improved battery pack design that enables easy maintenance, reliable, spill-free, and safe filling of phase change material (PCM) into the battery pack, thereby protecting electrical components from undesirable damage.
