Detailed description of the invention
Fig. 1 is a kind of line map of pure electric automobile battery pack preheating system of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of pure electric automobile battery pack preheating system, including lead storage battery, battery pack heating film and
BMS management system, the battery pack heating film are distributed between the mould group of battery pack, and the lead storage battery and boost module are electrical
Connection, the boost module are electrically connected heating controller, and the heating controller passes through relay and battery pack heating film electricity
Property connection, the BMS management system by CAN bus respectively with heating controller and battery pack communication connection.
The boost module from 12vDC boost in voltage to 43vDC, provides lead storage battery to power supply for heating controller.Institute
The instruction that heating controller receives BMS management system is stated, controls the closing or opening of relay to make battery pack heating film work
Or stop.The heating controller can adjust output power according to battery pack initial temperature, it is ensured that preheating system is in 2 minutes
Complete entire temperature-rise period.The BMS management system is to detect battery pack temperature and send instructions to heating controller.
The preheating system further includes vehicle-mounted T-box module, and the vehicle-mounted T-box module refers to receive client end AP P
It enables, and preheating communications protocol is sent to BMS management system by CAN bus, message is sent by BMS management system and is controlled to heating
Device processed controls relay closing or opening by heating controller, so that the work of battery pack heating film or stopping.The vehicle-mounted T-
Box module can be sent the battery pack temperature that BMS management system detects on client end AP P by wireless transmission.
The present invention, which is used, provides pre- thermoelectric power using lead-acid accumulator, itself is also to need because even pure electric automobile
One piece of lead-acid accumulator carries out low-voltage power supply, need to only calculate capacity needed for lead-acid accumulator according to demand, selects suitable hold
