Disclosed are a charging station, a charging system and method, and apparatuses, which solve the technical problem of how to control a high-voltage relay in a traction battery to be closed so as to form a charging circuit, without adding a bypass resistor. The charging system may control, by means of a controller (17) when starting charging, an insulation monitoring module (16), power supply access switches (13), a pre-charging switch (15), a battery, and one of battery access switches (14) to form a current path, so as to close the other battery access switch (14) after current is detected in the current path, i.e., controlling conventional devices in the charging circuit to form a current path without the need to provide a bypass resistor, thereby decreasing the manufacturing cost of the charging system and avoiding safety concerns caused by the bypass resistor. In addition, in the invention, the charging station comprises the charging system, the charging method can be used to control the charging system to charge a battery, and the apparatuses can be used to carry out and implement the above method.
