Abstract
The utility model relates to an intelligent charger with a temperature sensor for charging a lead-acid battery. The intelligent charger comprises a charger, and is characterized in that the charger is connected with the temperature sensor, and the temperature sensor is connected with the control circuit of the charger. The intelligent charger is characterized in that the temperature sensor comprises a heat-sensing resistor and an insulating shell; the heat-sensing resistor is arranged in the insulating shell and is connected with a plug by two lead-out wires; and the plug is connected with a socket on the charger. The intelligent charger with the temperature sensor has the advantages that the charging voltage of a storage battery pack is dynamically adjusted according to the temperature of the storage battery pack; during the whole storage battery pack charging process, different charging voltage can be used for different temperature, so that the temperature of the storage battery pack during the charging process is controlled; and high temperature does not cause the overcharge and the thermal lost control of the storage battery pack, and low temperature does not cause the undercharge of the storage battery pack so as to ensure the good conditions and the service life of the storage battery pack.
Description
Technical field
The utility model relates to a kind of intelligent charger to the lead accumulator charging with temperature sensor.
Background technology
At present, the transducer of measuring battery temp is not used in common lead accumulator charger charging, a fixed voltage pressure limiting charging is used in charging to the lead accumulator group, but in the charging process of batteries, the temperature of batteries is influential to charging, when temperature is too high, still use the fixed voltage charging, then can cause overcharging or thermal runaway of batteries, but the temperature of batteries in charging process do not measured at present.Therefore demand inventing a kind of intelligent charger that can when charging, detect the batteries temperature urgently, make in the battery charging process, use different charging voltages under the different temperatures situation, make the temperature of batteries in charging process controlled, can not cause overcharging and thermal runaway of batteries when temperature is high, temperature can not cause when low yet batteries owe fill, thereby guarantee intact and useful life of batteries.
Summary of the invention:
The purpose of this utility model is in order to overcome the deficiency that the lead accumulator charger can not detect the batteries temperature, a kind of intelligent charger temperature sensor is provided, a kind of intelligent charger of the utility model design with temperature sensor, comprise charger, it is characterized in that: charger is connected with a temperature sensor, and temperature sensor connects the control circuit of charger.It is characterized in that: temperature sensor is made up of thermistor and insulation crust, and thermistor is positioned at insulation crust, and thermistor is drawn lead by two and connected a plug, and plug is connected with socket on the charger.The utility model has the advantages that can be according to the charging voltage of the adjustment batteries of the temperature dynamic of batteries, in whole battery charging process, different temperatures can be used different charging voltages, make the temperature of batteries in charging process controlled, can not cause overcharging and thermal runaway of batteries when temperature is high, temperature can not cause when low yet batteries owe fill, thereby guarantee intact and useful life of batteries.
Description of drawings:
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is an arrangement of temperature sensor schematic diagram of the present utility model,
Fig. 3 is a thermistor connection diagram in the temperature sensor
Fig. 4 is an insulation crust interior view in the temperature sensor
1. chargers among the figure, 2. control circuit, 3. temperature sensor, 4. battery pack, 5. plug, 6. draw lead, 7. draw lead, 8. insulation crust, 9. installing and locating hole, 10. thermistor, 11. insulation crust preformed grooves, 12. thermistor sensible heat holes.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment:
Comprise charger among the figure, it is characterized in that: charger is connected with a temperature sensor, and temperature sensor connects the control circuit of charger.It is characterized in that: temperature sensor is made up of thermistor and insulation crust, and thermistor is positioned at insulation crust, and thermistor is drawn lead by two and connected a plug, and plug is connected with socket on the charger.
During use, temperature sensor is attached on the shell of institute's storage batteries, under the control of control circuit, charger is according to the change in resistance of the thermistor on the temperature sensor then, look into the temperature that resistance and temperature form obtain batteries, again according to temperature control charging.The different battery temp that detects, select how to charge, different temperatures can be used different charging voltages, make the temperature of batteries in charging process controlled, stop charging when temperature is high, can not cause overcharging and thermal runaway of batteries, temperature can not cause when low yet batteries owe fill, thereby guarantee intact and useful life of batteries.
