في البطارياتACلماذا لا يمكننا تخزين التيار المتردد

الاول نوضح ما هو التيار المتردد و التيار المستمر: 1. التيار الكهربائي المتردد هو الذي يغير قطبيته بتردد معين، مثلاً 50 هرتز، هذا يعني أنها ستكون موجبة و سالبة 50 مرة في الثانية الواحدة. 2. التيار الكهربائي المستمر هو الذي يحافظ على قطبيته. اي انها ستبقى دائما موجبة أو سالبة. لا يمكننا تخزين التيار المتردد […]

السيارات الكهربائة تسود الان لكن لا يوجد حل سحري

السيارات الكهربائية تسير أخيرًا في يجعل السائد. بعد عقود من انتظار ثورة السيارات الكهربائية ، ويتزايد عدد الأشخاص الذين يقودونها في النهاية حول العالم. مدفوعة بالنمو القوي في الصين وأوروبا ، تجاوزت مبيعاتها 10 في المائة من حصة سوق السيارات العالمية عام 2022. ……………………………. …… من الحكومات ، كبيرها وصغيرها ، تتطلع إلى تعزيز استخدام […]

الامان في السياره الكهربائيه

الأمان في السيارات الكهربائية هانحاول نلخصه في 3 نقاط: 1. مستوى الجهد الكهربي (مستوى الجهد) • المستوى A: يمكن للإنسان أن يتعرض يتعرض لكهرباء لا تتعدى 30V في حالة التيار المتردد و 60 V في حالة التيار المباشر (الذي يستطيع الفرد العادي أن يتعامل معه دون اذى ). • المستوى B: كل الانظمة التي تتعدى […]

تأثير الطقس البارد على مدى قيادة السيارات الكهربائية يتفاوت تأثير الطقس البارد على مدى قيادة السيارات الكهربائية وكفاءة البطاريات وأهمها الطقس البارد والحار، بالإضافة الى عادات السائق وظروف القيادة واستخدام وسائل الترفيه، ولكن تأثير الطقس البارد على مدى قيادة السيارات الكهربائية كبير نسبياً ويؤثر على قابلية شحن البطاريات وقدرتها على التخزين. تتراوح آثار الطقس البارد […]

ما هو السبب الالساسي في حدوث القفلة او الشرت او القصر في الدائرة الكهربائيه

يحدث الشُرز الكهربائي حين تصبح المقاومة بين اطراف الجهد الكهربائي المطبق في الدائرة صفرا. وذلك بتماس الخط الحار مع البارد او تماس خط فاز مع خط فاز اخر او تماس الخط الحامي مع الارضي (خط التأريض) في دوائر التيار المتغير .او القطب الموجب مع القطب السالب في دوائر التيار المستمر . فتكون المقاومة صفرا ويرتفع […]

انتشار السيارات الكهربائية يمثل تحول اساسى فى ثقافة القيادة والبنية التحتية ومع تزايد ظهور السيارات الكهربائية فى شوارعنا فإنها تأتى بأسئلة جديدة حول آدائها وطريقة استخدامها والتكيف معها. تخضع كل مركبة كهربائية لاختبارات صارمة قبل السماح لها بمغادرة مصنعها أو حتى الدخول في الإنتاج الضخم. لم يتم تصميم أي سيارة للقيادة على طرق غمرتها المياه […]
