  "textContent": "Thermal management of a backup battery unit for datacenter applications is described. In one embodiment, a backup battery unit includes one or more battery cells immersed in cooling liquid contained in an immersion tank. The immersion tank includes a temperature sensor. The battery unit also includes a first direct-current to-direct-current (DC/DC) converter electronically coupled to the battery cells and to an external power source for converting and controlling a charging voltage obtained from the external power source to charge the battery cells. The backup battery unit also includes a cooling-liquid pump for driving cooling liquid to the battery cells. The backup battery unit also includes a microcontroller coupled to the temperature sensor, the first DC/DC converter, and the cooling-liquid pump. The microcontroller is configured to control operations of the cooling-liquid pump based on temperature data obtained from the temperature sensor and an electrical current of the first DC/DC converter.",
