The invention relates to a self-adaptive type charger circuit of a power source of an electric automobile. Electronic measurement is adopted, charging current is automatically adjusted, or a computer battery management method is adopted, scale production is available, maintenance and work intensity is low, and efficiency is high. The self-adaptive type charger circuit of the power source of the electric automobile is characterized in that the charger circuit comprises DC power sources, multiple sets of circuit units and a battery pack are connected between the DC power sources in parallel, each set of circuit unit comprises a triode, an adjustable resistor and a voltage stabilizing diode, the collector electrode of each triode is connected with the positive electrode of the battery pack through the corresponding voltage stabilizing diode, the emitting electrode of each triode is connected with the negative electrode of the battery pack, and the base electrode of each triode is connected with the positive electrode and the negative electrode of the battery pack through resistors. Charging is achieved through the multiple sets of circuit units connected in parallel, and work efficiency and intensity are high.
Description
technical field [0001] The invention relates to a charger circuit, in particular to an electric vehicle power supply self-adaptive charger circuit. Background technique [0002] At present, in the application of batteries (battery batteries, lithium batteries, alkaline batteries, etc.), the series charging method is generally adopted, and the overall charging method is simple in application and easy to operate. The existing problems are: the battery charging effect is poor, the capacity is not ideal, and the actual measurement of a single battery is used to check the charging status of the battery. The method is relatively backward and the workload is relatively large, especially for individual batteries that need to be charged and processed separately. If electronic measurement is used to automatically adjust the charging current, or a computerized battery management method is used, it is more suitable for large-scale production and maintenance, with low work intensity and...
