Consequently, the importance of chargers for these machines is growing, and stable operation and prompt maintenance are essential requirements. However, currently distributed electric agricultural machinery chargers have the following issues in terms of maintenance.

[0003] First, when a problem occurs with an existing charger, it is difficult for users to identify the cause on their own, and even if an error code appears on the charger's display, ordinary users often do not understand the meaning of the code. Consequently, there is the inconvenience of having to request expert assistance because even simple problems cannot be resolved.

[0004] Second, if the charger does not function properly, users must call the manufacturer's customer service center directly or go through a separate online maintenance request process. This procedure is not only cumbersome, but immediate resolution is often difficult because it takes time for maintenance personnel to identify the problem.

[0031] The power converter (130) receives power from an external power source (300) and converts it into direct current or alternating current power input from a user input terminal (120).

[0032] Here, the power converter (130) comprises an inverter (131) that converts DC power into AC power, a converter (132) that converts DC power into other DC power or AC power, and a transformer (133) that converts AC power into other AC power.

[0033] The power converter (130) performs a combination of an inverter (131), a converter (132), and a transformer (133) to convert power received from a power source (300) into direct current or alternating current power input from a user input terminal (120).

[0034] The power distributor (140) designates and distributes the power converted through the power converter (130) to the charging port of the electric agricultural machine multi-charger (110). In addition, the power distributor (140) separately distributes the power that is always required to the input terminal (120) and the emergency communication unit (200).
