Abstract

The invention discloses a power supply system of a new energy automobile. The power supply system comprises a main battery, a switching control circuit, a standby battery, a solar energy collection device and an electric accessory; the main battery is connected with the charging pile joint; the charging pile joint is used for realizing the charging of the main battery through an external chargingpile; the solar energy collection device is connected with the standby battery and is used for charging the standby battery; the output ends of the main battery and the standby battery are connected to the electric accessory respectively through the switching control circuit; the switching control circuit is used for monitoring the remaining battery capacity of the main battery, conducting the power supply of the main battery to the electric accessory and cutting off the power supply of the standby battery to the electric accessory when the remaining battery capacity is higher than a preset threshold value, and cutting off the power supply of the main battery to the electric accessory and conducting the power supply of the standby battery to the electric accessory when the remaining battery capacity is lower than the preset threshold value. The system can prolong the time of driving endurance of an electric vehicle and effectively avoid the problem of power loss caused by the exhaustion of a car battery.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a new energy vehicle power supply system. Background technique [0002] With the continuous advancement of technology, new energy vehicles, especially pure electric vehicles, have gradually become popular in the market. At present, the vast majority of pure electric cars mainly use batteries such as lead-acid batteries, nickel-cadmium batteries, and lithium-ion batteries, but each of these batteries has certain defects. This results in problems such as short mileage of pure electric cars, high maintenance costs, and easy loss of power due to power depletion. Therefore, how to develop a novel new energy vehicle power supply system that can overcome the above-mentioned problems is a direction that those skilled in the art need to study. Contents of the invention [0003] The purpose of the present invention is to provide a new energy vehicle power supply...
