The invention relates to a low-voltage power supply system without a low-voltage energy storage battery and a vehicle, belongs to the field of electric vehicles and electric engineering machinery vehicles (or equipment), and aims to solve the problem that in the current field, low-voltage power supply needs to be provided by low-voltage energy storage equipment in the process from power-off to power-on of the vehicle. Comprising a high-voltage power distribution and control system, the high-voltage power distribution and control system comprises a high-voltage-to-low-voltage DC/DC and a constant power supply high-voltage-to-low-voltage module, and the high-voltage sides of the high-voltage-to-low-voltage DC/DC and the constant power supply high-voltage-to-low-voltage module are used The normally-powered high-voltage-to-low-voltage module is in power supply connection with the high-voltage power distribution and control system through a normally-open contact of the ignition switch; according to the invention, low-voltage energy storage equipment can be cancelled, and the weight and cost of the whole vehicle can be reduced.

    本发明涉及一种无低压储能电池的低压供电系统及车辆,属于电动汽车、电动工程机械车辆(或设备)领域,当前领域中,车辆从下电到上电过程中,需要借助低压储能设备提供低压电,本发明的无低压储能电池的低压供电系统及车辆,包括高压配电及控制系统,高压配电及控制系统包括高压转低压DC/DC和常供电高压转低压模块,高压转低压DC/DC和常供电高压转低压模块的高压侧用于连接动力电池;常供电高压转低压模块通过点火开关的常开触点供电连接高压配电及控制系统;高压转低压DC/DC供电连接整车低压母线,通过本发明可取消低压储能设备,实现整车减重、降本。
