Problems solved by technology

[0002] At present, when some power battery chargers on the market are not connected to the battery, the voltage at the output terminal of the charger will be equal to or higher than the charging voltage of the charger. On the one hand, if the voltage is higher than the safe voltage of the human body, the charger will increase Unsafe factors, on the other hand, the higher output voltage often requires the application of stricter charger certification standards, which increases the difficulty of certification for charger standards

Description

technical field [0001] The invention relates to a power battery charger system with adjustable open-circuit voltage, in particular to a power battery charger system which realizes different output voltages when the battery is not connected and when the battery is connected. Background technique [0002] At present, when some power battery chargers on the market are not connected to the battery, the voltage at the output terminal of the charger will be equal to or higher than the charging voltage of the charger. On the one hand, if the voltage is higher than the safe voltage of the human body, the charger will increase Unsafe factors, on the other hand, a higher output voltage often requires the application of stricter charger certification standards, which increases the difficulty of certification for charger standards. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a power bat...
