Abstract

A battery heating method and a battery heating system (100) for a vehicle battery are disclosed. The battery heating system comprises a vehicle battery (110), an auxiliary energy storage device (130),a direct current to direct current (DC-DC) converter (120) and a processing circuitry (102). The processing circuitry (102) is configured to cause the battery heating system (100) to operate in a first mode wherein the direct current to direct current (DC-DC) converter (120) is configured to control a current i to flow through the vehicle battery (110) in a first direction and operate in a secondmode wherein the direct current to direct current (DC-DC) converter (120) is configured to control a current i to flow through the vehicle battery (110) in a second direction.

Description

technical field [0001] This disclosure relates to the field of batteries and the field of heating of cold batteries. Background technique [0002] Today, it is very popular to use batteries to power various electrical devices. Batteries are used not only in small home electronics such as smartphones, tablets and laptops, but also in electrical equipment such as drills, lawn mowers, electric bicycles and electric cars. There are different types of batteries, especially rechargeable ones are very commonly used. [0003] Battery performance is affected by temperature. Most batteries have an optimum operating temperature. The usual optimum operating temperature is around 20 degrees Celsius or 68 degrees Fahrenheit. Batteries used indoors are generally not affected by different ambient temperatures. The room temperature is usually around the optimum operating temperature. However, batteries used in outdoor equipment are heated or cooled due to weather that affects the ambie...
