Battery management system can improve the utilance of battery, prevents that battery from occurring overcharging and overdischarge, prolongs the useful life of battery, and the state of monitoring battery is called for short BMS, below directly use BMS to explain battery management system.
Summary of the invention
There are the problems referred to above in the utility model to existing technology; Proposed a kind of vehicle-mounted charge machine electric supply installation, this electric supply installation can be monitored the temperature of power brick in real time under low temperature environment; And can supply power to the power brick preheating through charger, make safe and reliable charging and the discharge of battery ability.
The utility model is realized through following technical proposal: a kind of vehicle-mounted charge machine electric supply installation; Comprise BMS, vehicle-mounted charge machine and the battery system that is connected with the vehicle-mounted charge machine; The heating unit and several temperature sensors that is connected with BMS that are connected with the vehicle-mounted charge machine are installed on the described battery system; Be lower than the setup parameter in the BMS in the detected battery system temperature of temperature sensor; Described BMS is used to control the vehicle-mounted charge machine and supplies power to heating unit, and the heating unit heating is carried out preheating to battery system.
Be installed in temperature sensor in the battery system and monitor the temperature of battery system in real time; And send temperature signal and give BMS; After BMS receives the temperature signal of treatment of battery system; Compare with the parameter that is provided with in the BMS, thereby whether judge the current temperature of battery system low excessively, heat or stop heating through judging the heating unit that back control is connected with the vehicle-mounted charge machine.
In above-mentioned vehicle-mounted charge machine electric supply installation, be higher than the setup parameter in the BMS in the detected battery system temperature of temperature sensor, BMS can control the vehicle-mounted charge machine and finish to stop battery system being heated to the hot cell power supply.
In above-mentioned vehicle-mounted charge machine electric supply installation, described vehicle-mounted charge machine is connected with BMS, and the vehicle-mounted charge machine can be given the power supply of BMS and heating unit separately.
In above-mentioned vehicle-mounted charge machine electric supply installation, described heating unit is the calandria that adopts ptc material to process, and described calandria is connected with the vehicle-mounted charge machine.
In above-mentioned vehicle-mounted charge machine electric supply installation, described battery system comprises the power brick that battery unit is formed, and the plurality of temperature transducer is arranged in the power brick.
Prior art is compared, and this vehicle-mounted charge machine electric supply installation has the following advantages:
1, this electric supply installation can be under low temperature environment; Monitor the temperature of power brick in real time through temperature sensor; Whether BMS is lower than the power supply break-make that setup parameter is controlled charger through reduced temperature, thereby gives the power brick preheating, makes safe and reliable charging and the discharge of battery ability.
2, the BMS of this electric supply installation is connected with the vehicle-mounted charge machine with calandria; Under the lower situation of power brick temperature, give BMS and calandria heating by the vehicle-mounted charge machine; The power brick temperature is crossed under the low situation that there is not preheating and is supplied power by the vehicle-mounted charge machine in car exactly; Comprise that power brick supplied power to MBS by the vehicle-mounted charge machine in when heating, the infringement of battery is littler thus.

Fig. 1 is the structural representation of the utility model;
Among the figure 1, the vehicle-mounted charge machine; 2, BMS; 3, heating unit; 4, battery system.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1; This vehicle-mounted charge machine electric supply installation; Comprise BMS 2, vehicle-mounted charge machine 1 and the battery system 4 that is connected with vehicle-mounted charge machine 1; The heating unit 3 and several temperature sensors that is connected with BMS 2 that are connected with vehicle-mounted charge machine 1 are installed on the battery system 4, and whether BMS 2 can control vehicle-mounted charge machine 1 according to the temperature of the detected battery system 4 of temperature sensor and give heating unit 3 power supplies.When detected battery system 4 temperature of temperature sensor are lower than the setup parameter in the BMS 2, BMS 2 can control vehicle-mounted charge machine 1 and give heating unit 3 power supplies, and heating unit 3 heating are carried out preheating to battery system 4; When detected battery system 4 temperature of temperature sensor are higher than the setup parameter in the BMS 2, BMS 2 can control vehicle-mounted charge machine 1 and finish to stop battery system 4 is heated to the hot cell power supply.
