Embodiment Construction
[0036] Below in conjunction with accompanying drawing, structure and work flow of the present invention are further described;
[0037] see figure 1 , a charger that automatically recognizes the battery voltage gear, which is composed of an AC input terminal, a control circuit, a charger, a rechargeable battery, a switching power supply, and a single-chip computer, wherein one end of the control circuit is connected to the single-chip computer, and the other end is connected to the switching power supply. The other end of the power supply is connected to the relay and ground respectively. The single-chip microcomputer detects the signal between the battery to be charged and the charger through pin 4. After calculating and judging that the battery is a battery to be charged, the pin 3 of the single-chip microcomputer outputs a high level to turn on the transistor Q1. Then turn on the relay K1, the microcontroller controls the charging voltage through pin 1 and the charging curr...

The invention discloses a charger for automatically recognizing a voltage level of a battery, which belongs to the technical field of electrical. The charger consists of an alternating-current (AC) input end, a control circuit, a charger, a charging battery, a switch power supply and a single chip microprocessor, wherein one end of the control circuit is connected with the single chip microprocessor, the other end of the control circuit is connected with the switch power supply, the other end of the switch power supply is respectively connected with a relay and is grounded, the single chip microprocessor detects a signal between a to-be-charged battery and the charger through a pin 4, after the battery is judged to be the to-be-charged battery through the calculation, a pin 3 of the single chip microprocessor outputs high level to open a triode Q1 so as to further open the relay K1, the single chip microprocessor controls the charging voltage through a pin 1 and controls the charging current through a pin 2 so as to charge and discharge the battery in a pulse manner for 2 minutes, and then the charging is stopped. By adopting the charger, the voltage of the battery can be automatically recognized, the trouble that a user manually selects the voltage level when the battery is charged can be avoided, the broken battery and the aged battery can be automatically recognized, the user can be reminded of replacing the battery in time, the response time is short, and convenience in use can be realized.
Description
technical field [0001] The invention relates to a charger for automatically identifying battery voltage gears, in particular to a charger for 6V, 12V and 24V lead-acid batteries. Background technique [0002] Different batteries have different full voltage, the full voltage of 6V battery is 7.2V; the full voltage of 12V battery is 14.6V; the full voltage of 24V battery is 28.8V. [0003] The current chargers on the market are single-voltage chargers and multi-voltage chargers that need to manually switch voltage gears. A single voltage charger can only charge a single battery. For multi-voltage chargers that need to switch the voltage range manually, it is necessary to manually identify the battery type before charging and then manually select the voltage range of the charger. If the wrong selection is made, the battery may be damaged or not fully charged. Expertise. Contents of the invention [0004] The purpose of the present invention is to solve the disadvantages of...
