充電器是采用電力電子半導體器件，將電壓和頻率固定不變的交流電變換為直流電的一種靜止變流裝置。在以蓄電池為工作電源或備用電源的用電場合，充電器具有廣泛(fan)的應(ying)用前景。

       充電器有很多，如鉛酸蓄電池充電器、閥控密封鉛酸蓄電池的測試與監測、鎘鎳電池充電器、鎳氫電池充電器、鋰離子電池充電器、便攜式電子設備鋰離子電池充電器、鋰離子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池保護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路多功能充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)、無人飛(fei)機(ji)(ji)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)、智能機(ji)(ji)器(qi)(qi)(qi)(qi)(qi)人充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)、搬運(yun)機(ji)(ji)器(qi)(qi)(qi)(qi)(qi)人充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)，AGV小車充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)、經緯儀(yi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)輪(lun)椅充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)工具充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)、LED防(fang)爆電(dian)(dian)(dian)(dian)(dian)(dian)(dian)筒(tong)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)，掃地機(ji)(ji)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)，洗地機(ji)(ji)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)，割草機(ji)(ji)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)玩具充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)等(deng)。
