Abstract
The utility model provides a pure electric bus battery bin heat dissipating fan control circuit which comprises a power circuit, a heat dissipating fan, a rocker switch, a relay and a battery management system. The heat dissipating fan and the rocker switch are respectively connected to the two ends of the power supply in parallel. The heat dissipating fan is connected with a main contact of the relay in series. The rocker switch is connected with a coil of the relay in series. The battery management system comprises a fan control output end which is connected with the coil of the relay. According to the pure electric bus battery bin heat dissipating fan control circuit, the battery management system controls on-off of the relay through the fan control output end, so that the purpose of controlling starting and stopping the heat dissipating fan is achieved, the phenomenon that a battery is overheated due to the fact that the rocker switch of the heat dissipating fan is forgotten to be turned off is avoided, the problem of controlling the battery bin heat dissipating fan is fundamentally solved, and the safety and the reliability of the whole bus are improved.
Description
Technical field
The utility model relates to pure electric motor coach power cell storehouse radiating control technical field, specifically a kind of pure electric motor coach power cell storehouse control circuit of cooling fan.
Background technique
At present, conventional pure electric motor coach power cell storehouse control circuit of cooling fan generally adopts mechanical pressure switches, the start and stop of manual control battery compartment radiation fan.In car load running, if forgetting closed radiation fan switch or this radiation fan switch, driver damages, and electrokinetic cell there will be superheating phenomenon, and direct result may cause electrokinetic cell to catch fire, and has a strong impact on car load safety.Consider that electrokinetic cell is for the significance of car load, be necessary to design a kind of pure electric motor coach power cell storehouse control circuit of cooling fan, assurance radiation fan is normally worked, thereby guarantees the safety of electrokinetic cell and car load.
Model utility content
The purpose of this utility model is to provide a kind of pure electric motor coach power cell storehouse control circuit of cooling fan, and assurance radiation fan is normally worked, and avoids battery overheated, improves the safety and reliability of car load.
The technical solution of the utility model is:
A kind of pure electric motor coach power cell storehouse control circuit of cooling fan, comprise power supply, radiation fan, rocker switch, relay and battery management system, described radiation fan and rocker switch are connected in parallel on respectively both ends of power, described radiation fan is connected with relay main contact, described rocker switch is connected with relay coil, described battery management system comprises fan control output terminal, and described fan control output terminal is connected with relay coil.
Described pure electric motor coach power cell storehouse control circuit of cooling fan, described battery management system comprises Temperature sampler, described Temperature sampler is for gathering the temperature of electrokinetic cell.
Described pure electric motor coach power cell storehouse control circuit of cooling fan, described power supply is storage battery.
Described pure electric motor coach power cell storehouse control circuit of cooling fan, described relay main contact is arranged between radiation fan and positive source, and described relay coil is arranged between rocker switch and power cathode.
Battery management system of the present utility model is controlled the break-make of relay by fan control output terminal, thereby reach the object of controlling radiation fan start and stop, avoided because forgetting that the rocker switch of closed radiation fan makes battery occur overheated phenomenon, fundamentally solve the control problem of battery compartment radiation fan, improved the safety and reliability of car load.
Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of pure electric motor coach power cell storehouse control circuit of cooling fan, comprises storage battery 1, radiation fan 2, rocker switch 3, relay 4 and battery management system 5, and battery management system 5 comprises fan control output terminal 51 and Temperature sampler 52.
One end of rocker switch 3 is connected with the positive pole of storage battery 1, and the other end is connected with the anodal control end of relay coil 41, and the negative pole control end of relay coil 41 is connected with the negative pole of storage battery 1.
One end of radiation fan 2 is connected with the negative pole of storage battery 1, and the other end is connected with the output terminal of relay main contact 42, and the input end of relay main contact 42 is connected with the positive pole of storage battery 1.
Working principle of the present utility model:
Generally, closed rocker switch 3, storage battery 1 is relay coil 41 power supply, relay coil 41 energisings, control relay main contact 42 closures, storage battery 1 be radiation fan 2 power supplies, radiation fan 2 startups.In car load running, if driver forgets closed rocker switch 3, when battery management system 5 detects electrokinetic cell 6 temperature drift, by fan control output terminal 51, internal electric source is exported, be relay coil 41 power supplies, relay coil 41 energisings, control relay main contact 42 closures, storage battery 1 is radiation fan 2 power supplies, radiation fan 2 starts, avoided electrokinetic cell 6 overheated, realized the temperature of electrokinetic cell 6 is controlled.
The above mode of execution is only that preferred implementation of the present utility model is described; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
