Abstract
The invention discloses a temperature control system for a power cell of an electric vehicle, aiming at providing a charging system that can heat the battery. The temperature control system comprises a rechargeable battery, a battery management system, a charging interface, a charging machine, a temperature sensor, and an electric heating wire, wherein the battery management system is connected with the charging machine; the charging machine is connected with the rechargeable battery by the charging interface in the charging process; and the temperature sensor and the electric heating wire are connected with the battery management system respectively. During the charging process, when the temperature sensor detects that the temperature is excessively low, the charging is halted, the electric heating wire is electrified and the battery is pre-heated; and when the temperature is high enough, the electric heating wire is disconnected, the charging starts so that the service life of the battery can be protected, and the capacity of the battery can be ensured. The temperature control system is applicable to all electric vehicles, and is especially suitable for the electric vehicles in cold regions.
Description
Technical field
The present invention relates to a kind of electric automobile power battery temperature control system, especially relate to a kind of temperature controlled batter-charghing system of being with.
Background technology
In recent years, automobile industry development is swift and violent, low-carbon (LC), energy-conservation, reduce discharging the core competitiveness that has become automotive engineering.Electric automobile is increasing at the proportion that whole automotive field occupies with the characteristic of its green, environmental protection.
Electric automobile mainly by battery-operated, is to use one of process important step to battery charge.Under low temperature environment, battery intermediate ion rate of propagation is slack-off, and movement rate diminishes, and is difficult to be full of electricity, and battery capacity also can diminish, lifetime.
State Intellectual Property Office of the People's Republic of China discloses Granted publication and number has been the patent documentation of CN201590464U on 09 22nd, 2010, title is a kind of accumulator heating arrangement, it comprises the heating film that can paste on the accumulator surface, be provided with in the described heating film and make described heating film reach the preset temperature heater circuit, described heating film links to each other with power supply by power outlet.The weak point of this scheme is that detected temperatures need to judge whether beginning or stops heating automatically, and can not stop the charging process to battery under unaccommodated temperature.
Summary of the invention
The present invention solves the technical matters that the existing in prior technology battery charge is subjected to low temperature effect, provide a kind of can be to the electric automobile power battery temperature control system of battery heating.
The present invention is directed to above-mentioned technical matters is mainly solved by following technical proposals: a kind of electric automobile power battery temperature control system, comprise rechargeable battery, battery management system, charging inlet, charging set, also comprise temperature sensor, electrical heating wire, battery management system is connected with charging set, charging set connects rechargeable battery by charging inlet when charging, temperature sensor is connected battery management system respectively with electrical heating wire.During charging, cross when low when temperature sensor detects temperature, suspend charging, the electrical heating wire energising preheats battery, when temperature enough when high electrical heating wire close, begin charging, with protection battery serviceable life, guarantee battery capacity.
As preferably, battery management system is connected with charging set by the CAN bus.CAN bussing technique maturation, easy to use.
As preferably, electrical heating wire is arranged on the bottom of rechargeable battery.Electrical heating wire can fully heat rechargeable battery.
As preferably, temperature sensor is attached on the charging inlet limit.Temperature sensor is far away apart from electrical heating wire, and the temperature of guaranteeing whole rechargeable battery is all greater than detected temperature.
As preferably, temperature sensor is a PT100 mounted on surface temperature sensor, can be accurately, the fast detecting variation of temperature.
The substantial effect that the present invention brings is, effectively protects the life-span of rechargeable battery, accelerates charging rate under the low temperature environment, guarantees the capacity of rechargeable battery.

Among the figure: 1, electrical heating wire, 2, battery management system, 3, temperature sensor, 4, charging set, 5, charging inlet, 6, rechargeable battery, 7, outer containment vessel.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: present embodiment a kind of is with temperature controlled batter-charghing system, as shown in Figure 1, comprise battery management system 2 and the electrical heating wire 1 that is electrically connected with battery management system 2 respectively, temperature sensor 3, also comprise charging set 4 and rechargeable battery 6, charging set 4 is electrically connected with rechargeable battery 6 by charging inlet 5, and battery management system 2 is connected with charging set 4 by the CAN bus.Temperature sensor 3 is close to charging inlet 5.As shown in Figure 2, electrical heating wire 1 is arranged on the inner bottom part of outer containment vessel 7, and rechargeable battery 6 will be placed on outer containment vessel 7 the insides.Electrical heating wire 1 S-shaped layout guarantees that the bottom of rechargeable battery 6 is fully heated.Battery management system 2 is arranged on outer containment vessel 7 centre positions.Temperature sensor 3 is a PT100 mounted on surface temperature sensor.
During charging, when temperature sensor 3 detects temperature less than 0 degree centigrade, battery management system 2 sends to charging set 4 by the CAN bus and stops charging signals, the power supply that charging set 4 cuts off charging inlet 5, battery management system 2 is connected the power supply of electrical heating wire 1 simultaneously, electrical heating wire 1 is started working, and produces the temperature that heat provides rechargeable battery 6.When temperature sensor 3 detects temperature greater than 10 degrees centigrade, battery management system 2 disconnects the power supply of electrical heating wire 1, electrical heating wire 1 stops heat production, battery management system 2 sends the beginning charging signals by the CAN bus to charging set 4 simultaneously, 4 pairs of charging inlets 5 of charging set provide charging current, and rechargeable battery 6 is charged into electric energy.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technician of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as charging set, temperature sensor, battery management system morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
