Abstract

The present disclosure proposes a battery heating method and battery heating system (100) for a vehicle battery. A battery heating system includes a vehicle battery (110), an auxiliary energy storage device (130), a direct current-direct current (DC-DC) converter (120), and a processing circuit (102). The processing circuit (102) is configured to enable the battery heating system (100) to operate in a first mode and a second mode, wherein in the first mode, a direct current-direct current (DC-DC) converter (120) is configured to controlling current i to flow through the vehicle battery (110) in a first direction; in a second mode, the direct current-direct current (DC-DC) converter (120) is configured to be capable of controlling current i to flow through the vehicle battery in a second direction (110).

Description

Internal heating of the battery technical field [0001] The present disclosure relates to the field of batteries and the heating of cold batteries. Background technique [0002] Today, it is very popular to use batteries to power various electrical devices. not only smartphones, tablets and Small home electronics such as laptop computers, as well as electric drills, electric lawn mowers, electric bicycles, and electric vehicles Electrical equipment uses batteries. There are different types of batteries, especially rechargeable batteries are very common. [0003] The performance of a battery is affected by temperature. Most batteries have an optimum operating temperature. Usual optimum operating temperature That's about 20 degrees Celsius or 68 degrees Fahrenheit. Batteries used indoors are generally not affected by different ambient temperatures. room temperature degrees is usually around the optimum operating temperature. However, batteries used in outdoor equip...
