Detailed Description
Battery system charge temperature control method example 1:
the basic idea of the battery system charging temperature control method of the present embodiment is that: after the battery system enters a charging process, judging whether the lowest temperature of the battery system is smaller than or equal to a heating temperature starting threshold value of the battery system, if so, comparing the maximum output current of the battery currently available to the charger with the current maximum allowable continuous charging current of the battery system, and when the maximum output current of the battery currently available to the charger is larger, indicating that the charging speed of the battery system is limited by the current maximum allowable continuous charging current of the battery, and that the temperature of the battery system is lower, and heating the battery system is needed; when the maximum output current of the battery is smaller, the charging speed of the battery system is not limited by the maximum allowable continuous charging current of the battery, the temperature of the battery system is not low, and the battery system is not required to be heated.
Next, a method for controlling the charging temperature of the battery system according to the present embodiment will be described, as shown in fig. 1, which mainly includes the steps of:
1) Obtaining a current minimum temperature T of a battery system min Judgment of T min Whether or not the heating temperature start threshold T of the battery system is equal to or less heat-on If the ratio is less than or equal to the preset value, the step 2) is entered; if not less than or equal to the preset value, the battery system is not heated;
2) Judging whether the maximum output current of the charger is larger than the current maximum allowable continuous charging current of the battery, if so, inquiring a temperature value T1 required by the battery system when the battery system is charged according to the maximum output current of the charger, and entering the step 3); if not, not heating the battery system;
3) Judging T1-T min Whether the temperature is equal to or higher than 2 ℃ is judged, if yes, the battery system is heated; if not, the battery system is not heated.
In this embodiment, after the heating of the battery system is started, the determination of T is continued min If T1 is not less than, heating of the battery system is stopped. It should be noted that, in the whole charging process, tmin is dynamically changed along with the heat brought by battery heating and self-charging; the maximum output current of the battery which can be used by the battery at present is changed along with the change of the load of the battery, because some of the battery can charge a plurality of vehicles at the same time, the occupied power of the vehicle which is charged first is large, the allocated power of the vehicle which is charged later is small, if the vehicle which is charged first is full, the idle charging power is allocated to the vehicle which is charged later, and the charging power is improved; correspondingly, the table-look-up value of T1 is changed along with the change of the maximum output current of the battery and the change of the battery SOC of the battery.
In this embodiment, when the lowest temperature of the battery system is less than the heating temperature start threshold T of the battery system heat-on In the case of (2), whether the battery system is heated is further controlled according to the magnitude relation between the maximum output current of the battery currently available to the charger and the maximum allowable continuous charging current of the battery, compared with the prior art that the minimum temperature of the battery system is less than the heating temperature starting threshold T of the battery system heat-on The control strategy for heating the battery system can solve the problem of starting the threshold T due to the heating temperature heat-on And the energy waste and the long charging time caused by unreasonable arrangement are solved.
In this embodiment, the comparison is made between the maximum output current of the battery currently available to the charger and the maximum allowable continuous charging current of the battery, and as other embodiments, the comparison may also be made between the maximum output power of the battery currently available to the charger and the maximum allowable continuous charging power of the battery, when the maximum output power of the battery currently available to the charger is greater than the maximum allowable continuous charging power of the battery, the temperature value T2 required by the battery system when charging according to the maximum output power of the charger is queried, and the determination is made in step 3) of T2-T min And heating the battery system at the temperature of more than or equal to 2 ℃.
In this embodiment, T1 is obtained by a table look-up method, where a table is previously established, and a correspondence between a maximum allowable continuous charging current of the battery system and a temperature value and SOC is stored in the table, and according to the table, a temperature value required when the battery system charges according to a certain current can be queried. As another embodiment, T1 may be obtained by establishing a functional relationship instead of the table look-up, where the functional relationship may represent a correspondence between a maximum allowable continuous charging current and a temperature value of the battery system.
Step 3) of this embodiment determines that T1-T min Whether or not the temperature is equal to or greater than 2 ℃ is the same, T1-T min And T is 0 Compared with =2deg.C, the method can avoid the difference between T1 and T min Starting the heating system under the condition of small difference, eliminating temperature sampling error and service life loss of electric parts such as relay caused by frequent start and stop, and taking T1-T as other embodiments min Compared with other positive values, i.e. T 0 Take other positive values.
The battery system may be heated in the battery case, the battery case may be heated externally, the resistor may be heated, the liquid may be heated, and the current oscillation may be heated.

As described in the above embodiment 1 of the battery system charge temperature control method, the battery system charge temperature control method of this embodiment is also at T min Less than or equal to a heating temperature start threshold T of the battery system heat-on And T1-T min Heating the battery at a temperature of more than or equal to 2 ℃; at the same time, the restriction conditions are increased, namely, in the range of T1-T min ≥T 0 Or T2-T min ≥T 0 When the current highest temperature T of the battery system is established, the current highest temperature T of the battery system is judged max Less than B (B > T) heat-off ) If this condition is also satisfied, the battery system is heated.
The present embodiment also compares T1 with a heating temperature stop threshold T heat-off When T1 is less than or equal to T heat-off At the time, T is min The temperature is not less than T1 as a condition for stopping heating the battery; when T1 > Theat-off, tmin is greater than or equal to T heat-off As a condition for stopping heating the battery; at the same time, an additional heating stopping condition is added, namely the current highest temperature T of the battery system max Greater than B (B > T) heat-off ) The heating is also stopped.

When a is larger than or equal to c and larger than b, the corresponding control strategy is as follows:
inquiring the temperature T3 required by the battery system when the battery system is charged according to c, if T3-T min More than or equal to 2 ℃ and T3 is less than or equal to T heat-off Then the battery system is started to be heated and at T min Stopping heating the battery system when the temperature is not less than T3; if 0 ℃ is less than T3-T min Heating is not started when the temperature is less than 2 ℃; if T3-T min More than or equal to 2 ℃ and T3 is more than T heat-off Then the battery system is started to be heated and at T min ≥T heat-off The heating of the battery system is stopped.
