Production of electric chargers Electric vehicle chargers production whatever instruments and technologies you need

    I want to produce electric vehicle chargers to ensure that it is beneficial to the life of the battery and to ensure transmission safety. Ultra-low dropout chargers must be used. I use both ultra-low dropout linear stability guarantee circuits assembled with fully discrete components, and imported ultra-low dropout voltages. Linear integrated circuits, which also use switching modulation integrated circuits.

The problem you have expressed is caused by the low level of design of general electric bicycle chargers and great pressure on cost constraints. For high-energy batteries, it is emphasized that the temperature rise of the battery should be continuously detected; for lead-acid batteries, its tolerance is much stronger. If the temperature rise of the lead-acid battery is too high under the charging state, it has been overcharged very seriously.

It is very common that the charger cannot automatically jump the light. The easiest way is to connect the ammeter in series, manually monitor, and manually switch to a low floating charging voltage in time according to the actual situation; It takes a few days to interpret the assembly distribution of the circuit in detail, and to redraw the circuit diagram by reverse engineering, before the modification measures can be formulated.

The bigger difficulty is that the method of charging several batteries with a rated voltage of 12 volts in series has serious flaws. Interfering with charging is also a drop in the bucket, helpless, anxious, and unable to help.

The solution is to have one charger for each battery, and each battery has an independent voltmeter and ammeter for continuous monitoring. This kind of charger is not the current three-stage charger or the "computer intelligence" charger advertised by the company.
