碰碰車的供電又稱地網(wǎng)式供電：一種用條塊狀導(dǎo)體組合而成的供電網(wǎng)絡(luò)，是在一塊足夠大的絕緣板上，布置若干導(dǎo)電條，相鄰導(dǎo)電條的電極性相反，各導(dǎo)電條以適當(dāng)?shù)姆椒ǜ髯耘c電源的同名端相連。當(dāng)一個物體在供電網(wǎng)絡(luò)里自由活動時，可通過一個滑動觸點組從供電網(wǎng)絡(luò)中吸取電能或電信號。本條塊狀供電網(wǎng)絡(luò)，可直接應(yīng)用于給游樂園中的碰碰車供電。采用這種供電方法的碰碰車活動場所，地面不必再鋪鋼板，可直接利用普通地面。碰碰車的游戲規(guī)則是：駕駛者爭取最快在場內(nèi)完成繞圈，途中可以橫沖直撞，把對手的車碰開。當(dāng)時間到了，游戲結(jié)束時操作員把電源關(guān)上。碰碰車的速度通常很慢，就算是碰撞亦不會損害人和車。最早的碰碰車在1910年代已出現(xiàn)。
