A trailer DTU power supply system comprises a super capacitor and a power storage battery, the super capacitor and the power storage battery are connected to a trailer taillight circuit, the electric quantity of the super capacitor and the electric quantity of the power storage battery are distributed and used through an intelligent control circuit, and the super capacitor and the power storage battery provide a stable power supply for a DTU at the same time. The scheme of the super capacitor and the power storage battery perfectly solves the problems that the scheme of changing a headstock circuit in a large scale is needed, and the scheme of a single power storage battery is unstable in power supply source and cannot meet the use scenes of all vehicle types, and the key point is that a brake lamp power supply which cannot be used previously is fully utilized, and the special requirements in specific trailer drop and pull transportation scenes are met.
一种挂车DTU供电系统,包括超级电容与储电电池,所述超级电容与储电电池接入挂车尾灯线路,通过智能控制电路对超级电容与储电电池的电量进行分配使用,超级电容和储电电池同时给DTU提供稳定的电源。超级电容+储电电池的方案完美解决了需要大规模改车头电路的方案,以及单储电电池方案供电来源不稳定无法满足所有车型使用场景的问题,重点是充分利用了之前无法利用的刹车灯电源,满足特定的挂车甩挂运输场景下的特殊需求。
