Design of Large Capacity Lead Acid Battery Charger
Abstract Electric car has many advantages ,such as comfortable , clean, noiseless ,less pollution, and so on，which is the key to solve the problem of energy crisis and environment problem. There are many problems to develop electric car, one of which is charging technology. There are two kind of charging technology. One is charging through wire, and the other is wireless charging. And wireless charging is more attractive because it is more safe.Now many countries are researching on charging technology.This thesis designs a charger based on stm32f103 single chip microcomputer. It has many advantages such as small size, high efficiency and high reliability. The main circuit adopts double tube forward topology. And it adopts MOSFET parallel current-sharing. By using LM324 amplifier, it realizes the ability to charge constant current or constant voltage, depending on battery voltage. Considering high current, layout of the main circuit in the PCB is very important. Otherwise the circuit is very easy to burn out.To make a charger unit,first i have to read many books and search a lot data.Second i have to design the circuit,in this stage information searched before is very useful.After designing the circuit,it is time to draw the PCB and a lot of time was taken in this stage.Through the internet,many equipments and components were bought.After previous effort,it is time to assemble the PCB.However this is just the beginning,debugging the PCB is more difficult for me.In this stage ,many problems were found.After so many efforts i have learned a lot.The device that i have made is not so good,in the future i will do a better one.
