Abstract
The utility model discloses a control system for a power supply. The power supply is formed by connecting a plurality of single batteries in series. Each single battery is at least provided with an over-voltage/under-voltage detection integrated circuit (IC) chip for monitoring the voltage of the battery. A signal detected by each IC chip is transmitted to a control level state conversion circuit which can control a circuit breaker arranged on a trunk of the power supply. A tact switch is used for controlling an IC chip with a high under-voltage response value. The control system for the power supply is also provided with a time delay circuit for maintaining the state of the tact switch. Compared with the prior art, the control system for the power supply has the advantages that one over-voltage/under-voltage detection IC chip for monitoring the voltage is arranged on each single battery, and the signal detected by each IC chip is transmitted to the control level state conversion circuit which can control the circuit breaker arranged on the trunk of the power supply, so that the over-charge and over-discharge of a battery pack is avoided.
Description
[technical field]
The utility model relates to the control field of power supply, relates in particular to a kind of control system of electrical source of power.
[background technology]
Improving constantly of Along with people's living standard; Various media devices have expanded to each corner of life, have all installed multimedia equipment on the almost most automobile, like sound equipment, DVD equipment; Homer etc., even on a lot of motorcycles, also the sound equipment player can be installed.
The power supply of above-mentioned multimedia equipment derives from the battery pack (being commonly called as storage battery) of installing in automobile or the motorcycle; And these battery pack all have the control device of installing power supply; When the voltage of battery pack was lower than certain voltage, battery pack just can outwards not supplied power again, yet; Be not only multimedia equipment and can't work this moment, even electric motor car also can start.
In the application of reality, through regular meeting such situation takes place: the car owner brings into use aforesaid multimedia equipment under the situation that electric motor car does not start, and will take place so that multimedia equipment fully exhausts the electric weight in the battery pack and the phenomenon that can't start electric motor car.
In view of above drawback, the control system that is necessary to provide a kind of new electrical source of power in fact is to overcome above-mentioned defective.
[utility model content]
The purpose of the utility model is to overcome above-mentioned defective, and a kind of control system of simple in structure, the electrical source of power being convenient to control is provided.
The technical problem of the utility model is to realize by following technical scheme: a kind of control system of electrical source of power; Wherein, Said power supply is in series by some cells; Each cell is provided with an over-and under-voltage that is used to monitor its voltage at least and detects the IC chip, the IC chip detection to signal be sent to the control level state switching circuit, level state change-over circuit may command is arranged on the circuit breaker on the power supply trunk roads; The IC chip that one of them under-voltage response is high is controlled with touch-switch, and the control system of said electrical source of power also is equiped with delay circuit and keeps the touch-switch state.
Preferably, be provided with excess temperature checkout gear and overcurrent detecting device between said level state change-over circuit and the circuit breaker.
Preferably, described over-and under-voltage detects the IC chip and is provided with two kinds of different settings, and its effect is respectively low alarm of electric weight and secondary discharge protection.
Preferably, said power supply is in when discharge, and over-and under-voltage detects the IC chip detection when cell is discharged to scheduled voltage, and circuit breaker just can break off, and stops discharge, can push touch-switch and on-delay circuit subsequently and make power supply continue to discharge.
Preferably, at the interdischarge interval second time, can only put through delay circuit and low under-voltage response IC duplicate protection battery.
Compared to prior art; The utlity model has following advantage: owing to all be provided with an over-and under-voltage detection IC chip that is used to monitor its voltage on each cell; The IC chip detection to signal be sent to the control level state switching circuit; Level state change-over circuit may command is arranged on the circuit breaker on the power supply trunk roads, can guarantee that so just battery pack overcharge and discharge can not occur; Thereby use hand switch to recover the startup work that electric motor car can discharged and accomplish to IC output state assurance battery pack for the second time; Hand switch is selected touch-switch and delay circuit combination for use, can set discharge time for the second time flexibly, and the protection battery is only put; IC selects two kinds of different under-voltage responses for use, after the under-voltage protection first time, manually boots interdischarge interval under-voltage protection once more for the second time, and this protection priority is higher than above-mentioned delay protection.
[description of drawings]
Fig. 1 is the control system structural representation of the utility model electrical source of power;
Fig. 2 is that the partial circuit of the control system of the utility model electrical source of power connects sketch map.
[embodiment]
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described further.
A kind of control system 100 of electrical source of power; Said electrical source of power is in series by some cells; Each cell all is provided with an over-and under-voltage detection IC chip 10 that is used to monitor its voltage, and over-and under-voltage detects IC chip 10 can be provided with scheduled voltage, like this; When after the monomer voltage discharge, being lower than aforementioned scheduled voltage; Over-and under-voltage detects the IC chip just can be sent to control level state switching circuit 20 (traditional level shifting circuit) with its detected signal, and level state change-over circuit 20 just can may command be arranged on the circuit breaker 30 realization break functions on the power supply trunk roads, thereby the assurance cell is only put.In the utility model, over-and under-voltage response set point is first string 3.0V or all the other 1.9V.
In the control system of the utility model electrical source of power; The scheduled voltage that above-mentioned over-and under-voltage detection IC chip sets not is to be the limiting value of cell discharge; Promptly after cell is discharged to scheduled voltage; If the conducting again of power supply trunk roads, then cell can also continue discharge.For this reason, the control system 100 of the utility model electrical source of power also is equiped with delay circuit 40 and the touch-switch 50 that is used to control delay circuit between IC chip and control level state switching circuit.
When the user pushes touch-switch 50, just connect aforesaid delay circuit 40 and make power supply continue discharge, the user just can utilize this to discharge for the second time and realize the startup function of automobile usually.After the normal startup of automobile, delay circuit just can break off, and at this moment, the electric motor car after the startup just can charge to battery pack.
Trouble free service in order to ensure battery pack; Usually also between said level state change-over circuit and circuit breaker, be provided with excess temperature checkout gear 60 and overcurrent detecting device 70; Be used to detect the working temperature of battery pack and the size of electric current; When the working temperature of battery pack or electric current big or small undesired, the break-make that just can control circuit breaker in real time is to realize the protection to battery pack.
The control system of a kind of electrical source of power of the utility model; Be not restricted to described in specification and the execution mode; Therefore for the personnel of familiar field, can easily realize additional advantage and modification; So under the situation of the spirit of the universal that does not deviate from claim and equivalency range and limited and scope, the examples shown that the utility model is not limited to specific details, representational equipment and illustrates here and describe.
