As shown in fig. 1, the thermal insulation heating system for the power battery comprises a plurality of power battery packs 2 and a BMS 6, wherein an electric heating film is arranged in each power battery pack 2, and the thermal insulation heating system further comprises a fuel oil heating device 4 and a thermal insulation cover 1;
be equipped with controller 5 in the fuel oil heating device 4, controller 5 is connected with BMS 6, fuel oil heating device 4 is connected with power battery package 2 through liquid heat pipe way 3, and power battery package 2 is covered with the heat preservation and is equipped with 1.
Example 1
The utility model provides a pure electric vehicles power battery heating system that keeps warm mainly includes following two aspects:
(1) And (3) battery pack heat preservation:
through covering 1 at 2 externally mounted heat preservation of power battery package, cover 1 that keeps warm adopts integral mounting means, and the cover that keeps warm divides six piece installations of upper segment, lower piece, anter, back part, left part, right part totally, and it is fixed to tie up the rope through magic subsides, sheet metal strip, nylon between the cover that keeps warm, and this mounting means convenient to use, the cover 1 thickness that keeps warm in the 2 outsides of power battery package simultaneously is no longer than 10 millimeters, easily installation and change. The battery pack heat-insulating cover is made of heat-insulating materials with low heat conductivity coefficient, such as fireproof cloth and noise-reducing fireproof heat-insulating felt, and the heat-insulating effect is remarkable.
The heat preservation cover 1 can keep the power battery pack 2 less influenced by the external low-temperature environment and reduce the heat of the battery pack from diffusing outwards during heating. Meanwhile, the heat preservation cover 1 can also keep the temperature of the battery, so that the temperature of the battery is not reduced to be very low when the battery is placed in a low-temperature environment for a long time, and a good heat preservation effect is achieved on the battery pack.
(2) Heating the battery pack:
the common battery pack is heated by the electric heating film, the electric quantity of the battery pack is consumed by the electric heating film, the service efficiency of the battery is reduced, the heating rate of the heating film in independent work is limited, and the use requirement of rapid heating cannot be met.
The utility model is additionally provided with a set of fuel oil heating device 4, and a controller 5 (the model can be TFhd-11) of the fuel oil heating device 4 is communicated with a BMS 6 (the model can be MBMU 01);
