BACKGROUND OF THE INVENTION At present, when a car is started, a battery (battery) is provided to start motor power to start the engine. When the car is started, the engine-driven generator can continuously charge the battery, thereby supplying power for various types of electrical appliances in the car. In other words, the battery is an indispensable component for the normal operation of the car. Due to standby requirements, more and more electrical appliances in automobiles cannot be turned off even in the event of a vehicle stall, such as electronic clocks, keyless door lock systems, anti-theft systems, satellite navigation systems, photographic systems, and dashboard systems. . These electrical appliances require a small amount of current to maintain the value in the memory or to maintain certain logic states for continuous operation even when the car is turned off. Therefore, with the increasing number of automotive electrical appliances, even if the car is turned off, the battery's power consumption will increase significantly. In order to prevent the battery power from being consumed by the automotive electrical appliances and the inability to start the car, there are many battery-related patents that use dual-mode batteries, battery management systems, or emergency power technology, although they can all be used to avoid battery power. The effect of not being able to start the car is completely consumed, but the composition of the battery is more complicated and the production cost is higher. Secondly, traditional automobile batteries use lead-acid batteries because of their advantages of large electromotive force, simple structure, wide operating temperature, mature technology and low price. However, they are environmentally friendly. The problems, heavy weight and long service life are not overcome. In recent years, the lithium iron phosphate battery has a cycle life of more than 2,000 cycles, 5 times that of lead-acid batteries, and 6.6 times the discharge power of lead-acid batteries. Moreover, the charging time is less than 2 hours, only 1/4 of the lead-acid battery is needed, and the volumetric weight is only 50% of the lead acid. Therefore, it is expected to gradually replace the lead-acid battery in the future and apply to automobiles. Nevertheless, the current production cost of lithium iron phosphate batteries is still not low. In other words, lithium iron phosphate batteries have to completely replace the low-cost lead-acid batteries that have been used for many years in automobiles. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a battery module capable of solving the above-mentioned defects, which simultaneously uses two different types of batteries, and can combine the advantages of two different types of batteries, and Some electric door switches can control whether two batteries are energized, so that one of the batteries can maintain a full power state at any time, so that the car does not have insufficient power to start, and the composition is simple, effective, and practical. value.

As a preferred technical solution, the battery module further includes a casing, the first and second batteries and the power-off unit are disposed in the casing, and the casing is provided with two through holes, and the first battery includes Two conductive terminals protruding from the two through holes. As a further preferred solution, the casing includes an upper cover and a lower cover that are oppositely closed, and the two through holes are disposed on the upper cover.

In turn, the car does not have insufficient power to start, and the composition is simple and effective.

The first and second batteries 12 and 14 and the power-off unit 16 are disposed in the casing 19. The upper cover 22 is provided with two through holes 26, and the two conductive terminals 28 of the first battery 12 protrude from the two through holes 26 to electrically connect the starter motor 30 of the automobile. By the cooperation of the above-mentioned components, the battery module 10 of the present invention can provide the electric power required by the automobile, and the action mode and characteristics and functions thereof are as follows: When the electric door switch 18 is located in the lock section or the driver of the vehicle switches it to the attached When the power supply section is powered, the power-off unit 16 can be operated to cause the first and second batteries 12 and 14 to be powered off. In this way, only the second battery 14 can be powered, and the first battery 12 is not consumed. Power (automatic part of the car when the switch 18 is switched to the power supply section of the accessory) The power is still supplied by the second battery 14). When the driver of the vehicle switches the switch 18 to the open section, the power-off unit 16 can be reactivated to electrically connect the first and second batteries 12, 14 so that the driver switches the switch 18 to the start. When the car is started, there is sufficient power for the starter motor 30 to start the car. As can be seen from the above, the first battery 12 and the second battery 14 of the battery module 10 are different types of batteries, which can combine the advantages of different types of batteries. Next, by using the switch 18 to control the operation of the power-off unit 16, the first and second batteries 12 and 14 can be further controlled to be energized, and not only the power of the second battery 14 is maintained in the vehicle when the vehicle is turned off. The operation of the electronic component does not consume the power of the first battery 12, so that sufficient power is available for the vehicle to start at any time (even if the power of the second battery 14 is weakened, after the first battery 12 is energized, the first battery 12 The power is enough to provide the car to start). Furthermore, the power generated by the generator in the vehicle starting state can be simultaneously replenished to the first and second batteries 12, 14. Therefore, the first battery 12 can maintain full power at any time, thereby enabling the vehicle to be used with the battery module 10. There will be no shortage of power to start. In other words, the present invention does not need to add an electronic system for detecting the power of the battery, and it is also unnecessary to add a management system with a residual power reserve function, and only cleverly utilizes the original multi-segment switch of the automobile to urge the power-off unit 16 to By operating in a predetermined manner, the battery power management function can be obtained. Compared with the well-known automobile battery, the composition is obviously simpler, more effective, and has practical value. In addition, the first and second batteries 12 and 14 can also respectively connect a plurality of batteries in parallel (or in series) to form a battery pack, respectively, which can increase the storage amount and the supply amount of electric power. It should be noted that, in the present invention, the power-off unit is not limited to the power-off switch, and may be a circuit or an electronic component that is controlled to cut off or connect the circuit, such as a power-off circuit or a relay, and only needs to accept the switch. Switching control causes the first and second batteries to be powered off or energized The state, which meets the needs of the present invention, is within the technical scope of the present invention. In summary, the battery module provided by the present invention uses different types of first and second batteries, which can combine the advantages of different types of batteries, and uses a switch to control the operation of the power-off unit. The first battery and the second battery can be further controlled to be energized, so that the first battery can maintain a full power state at any time, so that the vehicle does not have insufficient power to start, and the composition is simple, effective, and has practical value. .
