Electric vehicle, controller and methanol to hydrogen battery control system and method

Abstract

The invention discloses a control method for a methanol to hydrogen battery used in an electric vehicle. The control method includes the following steps that whether a power adjusting instruction is received or not is detected, and if yes, the next step is executed; according to the power adjusting instruction, the initial power of the methanol to hydrogen battery is adjusted step by step multiple times to needed power based on preset variable quantity. The invention further discloses a control system for the methanol to hydrogen battery. The invention further discloses a controller comprising the control system for the methanol to hydrogen battery. By means of the control method, heat balance of the methanol to hydrogen battery can be effectively controlled, temperature of the methanol to hydrogen battery can be controlled, and the problem that a catalyst in a reaction chamber loses activity as the temperature is out of control, and the service life of the battery is shortened is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a method for controlling a methanol-hydrogen production battery. In addition, the invention also relates to a control system of a methanol-hydrogen production battery. In addition, the present invention also relates to a controller with the control system. The invention also relates to an electric vehicle with the controller. Background technique [0002] As we all know, there are two main chemical reaction links in methanol reforming hydrogen production methanol hydrogen production battery, namely the autothermal reforming of methanol to produce hydrogen and the combination of hydrogen and oxygen through proton exchange membrane to generate electricity. Both of the above two reactions need to work on a suitable catalyst environment at the active temperature.
