    • An electric vehicle is proposed which comprises a reversible power supply (or which is coupled with a reversible power supply), one or more electric motors that are connected to wheels via a mechanical transmission (or without such transmission), one or several reversible converters, which make it possible to control the speed and/or torque of the aforesaid electric motors in all four quadrants of electromechanical characteristic, a high capacity capacitor (supercapacitor) and a ballast resistor.The vehicle is provided with a reversible dc step-up/step-down transformer, two current sensors, two voltage sensors, a vehicle speed sensor, a speed sensor for one of the electric motors and a control system, wherein one or several reversible converters are connected directly to the terminals of the reversible power supply. The supercapacitor is connected to the terminals via the reversible transformer. The ballast resistor, parallel-connected to a bypass diode, is connected in series with a discharge key to the same terminals. One sensor indicates the current value and direction of the reversible power supply, the second sensor takes measurements of coil (inductance choke) current being a component of the transformer. One voltage sensor measures the voltage at the capacitor terminals. The outputs of the aforesaid sensors, together with the output of the speed sensor, are connected to the inputs of the control system, the outputs of which are connected to the control inputs of the transformer and a discharge key. The technical result is a reduction in energy loss as a result of the increased use of recovered energy.
    • 提出了一种电动车辆,其包括可逆电源(或与可逆电源耦合),经由机械变速器(或没有这种变速器)连接到车轮的一个或多个电动机,一个或多个可逆转换器, 这使得可以控制机电特性的所有四个象限中的上述电动机的速度和/或扭矩,大容量电容器(超级电容器)和镇流电阻器。 该车辆设置有可逆直流升压/降压变压器,两个电流传感器,两个电压传感器,车速传感器,用于电动机之一的速度传感器和控制系统,其中一个或多个可逆转换器 直接连接到可逆电源的端子。 超级电容器通过可逆变压器连接到端子。 并联连接到旁路二极管的镇流电阻器与放电键串联连接到相同的端子。 一个传感器表示可逆电源的当前值和方向,第二个传感器测量作为变压器组件的线圈(电感扼流圈)电流。 一个电压传感器测量电容器端子处的电压。 上述传感器的输出与速度传感器的输出连接到控制系统的输入端,控制系统的输出端连接到变压器的控制输入端和一个放电键。 技术结果是由于回收能源的使用增加而导致的能量损失减少。
