Description

Direct current quick charging heating control method and system in low-temperature environment
Technical Field
The invention relates to a low-temperature charging auxiliary technology of an electric automobile power battery, in particular to a heating control method and a heating control system during direct current quick charging under a low-temperature environment.

With the continuous development and popularization of new energy automobiles, the requirements of users on the performance of the automobiles are also continuously improved. In northern areas, particularly in winter particularly cold areas, the situation that the battery needs to be charged in a low-temperature environment is often encountered, but the battery is irreversibly damaged by charging the battery in the low-temperature environment, and then the battery pack is heated very necessarily.
At present, the low-temperature heating modes of vehicles on the market are mainly divided into two modes, namely heating by using battery pack quantity and heating by using an on-board charger.
And when the temperature is too low and the heating is needed, the whole vehicle controller sends PTC power consumption to the battery management system, and the battery management system distributes the battery pack electric energy to perform PTC heating control.
The heating by using the vehicle-mounted charger occurs in the process of alternating-current slow charging, and the method can be divided into the following steps: a: the alternating-current slow charging process begins; b: receiving a heating request; c: the battery management system controls the vehicle-mounted charger to heat the PTC, and disconnects the total positive and total negative relays of the battery pack to prevent current from flowing to the battery pack; d: and after heating is finished, closing the battery pack total positive and total negative relay, and switching back to a charging mode.
The scheme of heating by using the battery pack power can only carry out heating control when the battery pack power is higher, and when the power is lower or no power is supplied, the battery pack power can not be heated, and even can not be charged because the battery pack power can not be heated.
The vehicle-mounted charger is used for heating, although the most common heating mode is applied at present, the continuous high-load operation time of the vehicle-mounted charger can be further prolonged while the vehicle-mounted charger is heated, and the probability of potential safety hazards is gradually increased along with the aging of the charger.
