Benefits of technology

This patented technology describes an improved design for electric vehicles that uses both conventional batteries (DC) and fuel cells called hydrogen gas or methanol). It allows for more efficient charging than traditional methods like plugging into regular wires. By connecting sources modules together serially instead of sequentially, it reduces component count while still providing effective performance compared to existing designs. Overall, this innovation improves efficiency and reduced size and costs over current systems.

Problems solved by technology

This patented describes a problem where electrical vehicles require more expensive equipment such as batteries due to their higher costs compared to traditional gasoline engines used for transportations. Additionally, these systems often use multiple components leading to larger sizes and increased manufacturing expenses. To solve this issue, there needs a new solution called a bi-directionally oriented architecture (BOS) integrating both primary and secondary converters into a single unit.

Abstract

The invention provides a double-order topology integrated structure of a bidirectional energy conversion system, a control method and a vehicle. The double-order topology integrated structure comprises a charger source side module, a transformer and resonance topology module and a charger secondary side high-voltage side module. The charger source side module comprises a first inductor, three half-bridge circuit units and a first capacitor; wherein one end of the first inductor is connected with a live wire/zero wire of the alternating current power supply module; after the three half-bridge circuit units are connected in parallel and then are connected with the first capacitor in parallel, a first leading-out end is connected with the other end of the first inductor, and a second leading-out end is connected with a null line/live line of the alternating-current voltage module and one end of the alternating-current side of the transformer and resonant topology module; and the third leading-out end is connected with the transformer and the other end of the alternating current side of the resonant topology module. The number of used components can be reduced, the size of the bidirectional energy conversion system is reduced, and the cost is reduced.
