1 fuse tube fuseThe fuse tube fusing shows that the internal circuit of the electric charger has short circuit or over-current fault. This is because the charger for a long time to work in high voltage, high current status, the higher the failure rate of internal components. In addition, the power grid voltage fluctuations, surge will cause the instantaneous increase in the charger and fuse fuse.2 the DC voltage output is too highThis failure is often to voltage sampling and voltage control circuit is abnormal, in the electric vehicle charger, DC output, sampling resistor, error sampling ampli...

Constant current charging of electric vehicle charger constant current charging means that the battery is charged with piecewise constant current charging method, and the current is adjusted by charging device to achieve. Its main feature is that the charging method has greater adaptability, and the charging current can be arbitrarily selected and adjusted. So it can be for different condition and battery state of charge (such as battery charging, battery charging at the beginning of the used and went charging). The utility model is especially suitable for charging small batteries with long cu...

Nowadays, the market competition is fierce, so is the electric vehicle industry. Battery is the main driving force of electric vehicles, equivalent to the car's engine. Electric vehicle charger also plays a quite important role, the current electric vehicle charger varieties, pulse charger, lithium battery charger and so on, if the electric car charger use inferior, not only reduces the electric car battery car mileage is reduced and the service life of electric vehicle battery.Then, how to buy electric car charger?1, because in the use of electric vehicles, because the charger is an exter...

The lithium battery charger is a charger specially designed for charging lithium ion batteries. The lithium ion battery has higher requirements for the charger, so it needs to protect the circuit, so the lithium battery charger usually has higher control precision, and can charge the lithium-ion battery with constant current and constant voltage.Precautions for lithium battery chargers1. the work of the charger should be consistent with the charging pool. If the charger works in a lithium battery state to allow Ni MH or Ni Cd batteries, battery charging will greatly reduce working hours. If th...
