Explain the principle of voltage and current regulation when charging

When you attach a battery charger, the charger can put out a range of impedances (that is, it can vary voltage to current). If it has a FIXED impedance, it can only charge the battery up to that particular volts/current (its impedance), which wouldn''t be much use. Now, it is the BMS that controls the charging of the battery in an EV.

6 Frequently Asked Questions about “Maximum battery charging current in the EU”

Does the EU have a universal charger for electronic devices?

The EU has implemented a universal charger for electronic devices to reduce waste. All new devices sold in the EU must now support USB-C charging.

What is the EU common charger directive?

Harmonising fast charging technology: New rules help to ensure that charging speed is the same when using any compatible charger for a device. The EU's Common Charger Directive was approved by the Council of the EU in October 2022. Manufacturers were given a transition period to adjust their designs and ensure compliance.

What is the maximum voltage for European standard AC/DC charging interfaces?

The maximum voltage for European standard AC is 480V AC and the maximum current is 63A; The maximum DC voltage is 1000V DC and the maximum current is 200A DC (based on the 2014 version of data). Table 7. Rated values of European AC/DC charging interfaces

Does the EU support USB-C charging?

The EU has got you covered! Because the EU has standardised charging ports for mobile phones and other portable electronic devices, all new devices sold in the EU must now support USB-C charging. This will reduce the number of chargers you need to buy, help minimise electronic waste and simplify your everyday life.

What are European charging infrastructure regulations?

The current European charging infrastructure regulations set minimum requirements for charging stations. In the near future, these will include smart charging, which is in turn enabled by digital communication standards.

Should smart charging standards be adopted at the European level?

The Commission has asked European Standardisation Organisations to adopt key smart charging standards at the European level, which should at the same time speed up the international standardisation process. Among these are standards that will be based on ISO 15118, IEC 63110 and IEC 63119 (see page 16).
