Abstract
The present invention includes providing a plurality of batteries connected to a power generation line connected to an external generator, measuring the temperature of a space in which the plurality of batteries are positioned, and controlling charging and discharging between the plurality of batteries according to the measured temperature so as to raise the temperature of the plurality of batteries, and the present invention can prevent a reduction in the temperature of the battery.
Claims16
A battery device, comprising:
- a power generation line connected to an external generator;
- a plurality of batteries configured to be connected to the power generation line to receive and be charged by power from the external generator via the power generation line based on a voltage of the plurality of batteries;
- a hot-air blower configured to supply hot air to a space in which the plurality of batteries are positioned;
- a controller configured to control charging and discharging between the plurality of batteries according to a temperature of the space in which the plurality of batteries are positioned to raise the temperature of the plurality of batteries;
- a first switch installed on the power generation line to connect the plurality of batteries to the external generator or to disconnect the plurality of batteries from the external generator based on the voltage of the plurality of batteries and on the temperature of the space in which the plurality of batteries are positioned;
- and
- a second switch installed between the hot-air blower and the plurality of batteries to connect the hot-air blower to at least one of the plurality of batteries or to disconnect the hot-air blower from the plurality of batteries based on the voltage of the plurality of batteries and on the temperature of the space in which the plurality of batteries are positioned,
- wherein the plurality of batteries are connected in parallel, and final terminals of the plurality of batteries connected in parallel are configured to be connected in parallel to the power generation line and the hot-air blower.
