Portable charger and controller thereof

Abstract

The invention provides a portable charger and a controller thereof. The portable charger is provided with the controller, the controller comprises a control chip, a temperature detection module, a power supply voltage detection module, a current detection module, a power supply phase sequence detection module, a pulse modulation circuit and a relay protection circuit; and the control chip is electrically connected with the temperature detection module, the power supply voltage detection module, the current detection module, the power supply phase sequence detection module, the pulse modulationcircuit and the relay protection circuit. The portable charger can generate different PWM signals to be connected with an electric vehicle and communicates with the electric vehicle, and thus the basic charging function is achieved; and the portable charger can be compatible with electric vehicle charging protocols of different countries and regions, and meanwhile has the protection functions such as over-temperature protection, overcurrent protection, electric leakage protection, phase sequence protection, power supply voltage protection and relay protection.

Description

technical field [0001] The invention relates to the field of charging equipment for electric vehicles, in particular to a portable charger and a controller for providing electric energy for electric vehicles. Background technique [0002] With the increasing popularity of electric vehicles, more and more people are paying attention to the charging methods of electric vehicles. At present, the charging facilities for electric vehicles are mainly charging piles. The charging piles can be fixed on the ground or walls and installed in public buildings (public buildings, Shopping malls, public parking lots, etc.) and residential area parking lots or charging stations, can charge various types of electric vehicles according to different voltage levels. [0003] The electric vehicle charger is a charging device specially configured for electric vehicles. Most of the existing electric vehicle chargers are standard equipment on the vehicle. When the electric vehicle leaves the factor...

AI Technical Summary

Problems solved by technology

[0005] However, in order to improve the power and energy utilization of electric vehicles, the voltage of power storage batteries is getting higher and higher, and the safety hazards in the charging process of electric vehicles are also getting higher and higher. Most of the existing electric vehicle chargers have Charging protection function, that is, the charger controls the switch of the charger by detecting the voltage value of the battery of the electric vehicle, but the quality of the products of many charger manufacturers is uneven or the protection function of the charger is not comprehensive enough. The car battery is damaged or the charger cannot be charged normally. At the same time, because the protection function of the charger is not comprehensive enough, there are certain safety hazards, which may lead to accidents, damage to the vehicle and personal safety, and bring great harm to users. inconvenient
