The invention relates to a monitored DC voltage charging method for charging a vehicle-side traction battery (B1, B2) by means of a vehicle-side charging circuit by means of a vehicle-external charging voltage source (SO). The traction battery (B1, B2) has a nominal voltage of at least 500 V. In a test step, whether the charging voltage source (SQ) has an overvoltage protection, which comprises a voltage limiting element (E), which is arranged between a charging voltage potential of the charging voltage source (SQ) and a ground potential and is designed to transition from a voltage below a nominal voltage into an electrically conductive state, is detected. If it is detected in the checking step that the charging voltage source (SQ) has no overvoltage protection (E), a DC voltage is transmitted from the charging voltage source (SQ) to the traction battery (B1, B2). If it is detected in the checking step that the charging voltage source (SQ) has an overvoltage protection (E), at least one DC voltage charging mode for transmitting the DC voltage from the charging voltage source (SQ) to the traction battery (B1, B2) is prevented. The invention further relates to a vehicle-side charging circuit, which is designed to carry out the method.

    本发明描述了一种用于通过车辆侧的充电电路借助于车辆外部的充电电压源(SO)来对车辆侧的牵引蓄电池(B1、B2)充电的经监测的直流电压充电方法。牵引蓄电池(B1、B2)具有至少500V的额定电压。首先在检验步骤中检测所述充电电压源(SQ)是否具有过压保护,该过压保护包括限压元件(E),该限压元件设置在充电电压源(SQ)的充电电压电位与接地电位之间并且设立用于,自低于额定电压的电压起转变到能导通的状态中。如果在检验步骤中检测到充电电压源(SQ)不具有过压保护(E),则将直流电压从充电电压源(SQ)传输到牵引蓄电池(B1、B2)处。如果在检验步骤中检测到充电电压源(SQ)具有过压保护(E),则阻止用于将直流电压从充电电压源(SQ)传输到牵引蓄电池(B1、B2)处的至少一种直流电压充电模式。此外描述了一种车辆侧的充电电路,其设立用于实施所述方法。
