Embodiment Construction
[0049] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0050] figure 1 It is an application scenario of a charging method for a vehicle to be charged according to the present disclosure. Such as figure 1 As shown, the vehicle 1 to be charged is connected to a power supply vehicle 2 for charging, and the power supply vehicle 2 is a DC power supply vehicle.
[0051] figure 2 It is a flow chart of a charging method for a vehicle to be charged according to an exemplary embodiment of the present disclosure. Such as figure 2 As shown, the method includes step 201 and step 202.
[0052] In step 201, the temperature of the battery of the vehicle to be charged and / or the vehicle for power supply is acquired.

The invention relates to a to-be-charged vehicle charging method and a device thereof, a storage medium and a to-be-charged vehicle, and the product is used for a power supply vehicle to charge the to-be-charged vehicle, and is characterized in that the method comprises the steps that the temperature of the to-be-charged vehicle and / or the temperature of a battery of the power supply vehicle are / is acquired; and when the temperature of the to-be-charged vehicle battery is smaller than a first preset temperature and / or the temperature of the power supply vehicle battery is smaller than a second preset temperature threshold value, the to-be-charged vehicle battery is controlled to be charged and discharged alternately through the power supply vehicle to generate heat, so that heating of the to-be-charged vehicle battery or the power supply vehicle battery is achieved. Thus, in the charging process of the to-be-charged vehicle, alternate charging and discharging of the to-be-charged vehicle battery are controlled by controlling the battery voltage of the to-be-charged vehicle battery, then heating of the to-be-charged vehicle battery is achieved, and the problem that charging of the to-be-charged vehicle battery cannot be completed under the condition that the temperature is low is solved.
Description
technical field [0001] The present disclosure relates to the technical field of vehicles to be charged, and in particular, to a charging method, device, storage medium and vehicle to be charged. Background technique [0002] Due to the low-temperature characteristics of the battery, the performance of the battery will be significantly reduced in a low-temperature environment, which makes it difficult to charge the battery of the vehicle to be charged when the ambient temperature is low. Therefore, in order to ensure that the vehicle battery to be charged can be charged normally when the ambient temperature is low, it is necessary to heat the battery to an appropriate temperature range. [0003] In the prior art, when heating the battery of the vehicle to be charged, a special device for heating the battery of the vehicle to be charged is usually added, which not only increases the complexity of the structure of the vehicle to be charged, but also increases the cost.
