Problems solved by technology

However, compared with normal temperature (for example, above 15°C), the battery polarization in low temperature environment (for example, below 0°C) is very large, and the charging capacity drops rapidly
If the user uses an external power supply device (for example, a charging pile) to charge the battery of an electric vehicle in a low temperature environment, the performance and service life of the battery will be reduced, and its safety may be greatly reduced

Abstract

The invention relates to an energy processing device and method, and a vehicle. The device comprises an oscillation heating circuit connected with a battery of the vehicle, an energy consumption circuit and a controller, wherein the energy consumption circuit is used for being connected with external power supply equipment; and the controller is respectively connected with the oscillation heating circuit, the energy consumption circuit and the battery and is used for controlling the oscillation heating circuit to heat the battery in a first preset state and receiving energy provided by the external power supply equipment by utilizing the energy consumption circuit during oscillation heating. Therefore, in a first preset state, when the oscillation heating circuit is used for heating the battery, the energy consumption circuit is used for receiving energy provided by the external power supply equipment, in this way, it can be avoided that the external power supply equipment is shut down or a charging fault occurs due to the fact that the voltage is unstable in the battery heating period, and therefore secondary starting of the external power supply equipment is avoided.

Description

technical field [0001] The present application relates to the field of vehicles, in particular, to an energy processing device, method and vehicle. Background technique [0002] Because batteries have the advantages of high safety, long life, and large energy, they are widely used in electric vehicles. However, compared with normal temperature (for example, above 15° C.), the polarization of the battery in a low-temperature environment (for example, below 0° C.) is very large, and the charging capacity drops rapidly. If the user uses an external power supply device (for example, a charging pile) to charge the battery of the electric vehicle in a low temperature environment, the performance and service life of the battery will be reduced, and its safety may be greatly reduced. [0003] Therefore, when charging the battery through an external power supply device, the temperature of the power battery is usually detected first, so as to judge whether it is necessary to heat the...
