Definitions
- the invention relates to a system comprising a charging connector for attachment to the vehicle body of an electric or hybrid vehicle and a charging electronics unit that can be installed in the electric or hybrid vehicle for controlling the charging of a battery of the electric or hybrid vehicle, wherein the charging connector has at least one pair of DC contacts and a pair Has AC contacts and the charging electronics unit is provided with a DC receiving part for connecting to the DC contacts and an AC receiving part for connecting to the AC contacts.
- a system comprising a charging connector for attachment to the vehicle body of an electric or hybrid vehicle and a charging electronics unit that can be installed in the electric or hybrid vehicle for controlling the charging of a battery of the electric or hybrid vehicle
- the charging connector having at least one pair of DC contacts and a Pair of AC contacts
- the charging electronics unit is provided with a DC receiving part for connecting to the DC contacts and an AC receiving part for connecting to the AC contacts
- the charging connector has a short-circuiting device with which a respective AC contact can be short-circuited with a respective DC contact in such a way that via the AC contacts Current received from the charging electronics unit can only be received from the DC contacts and forth.
- alternating current contacts When we talk about alternating current contacts, this refers to the outer conductors and the neutral conductor (center conductor), which are also intended for charging with alternating current.
- An external conductor also known colloquially as a phase
- a neutral conductor is a conductor that is electrically connected to the neutral point and capable of contributing to the distribution of electrical energy.
- the contacts that are present are referred to as AC contacts, labeled L1, L2 and L3 (outer conductor) and N (neutral conductor).
- the basic idea of the present invention is therefore to achieve an increase in the cable cross-section for charging the electric or hybrid vehicle, which is equipped with a conventional charging connector, such as a charging plug according to the European standard IEC 62196 Type 2, by simultaneously connecting the AC contacts and the DC contacts can be used for DC charging.
- An IEC 62196 Type 2 charging plug provides two DC contacts and four AC contacts. There is also a protective conductor contact and two contacts for charging communication.
- it is not intended to use the DC contacts and the AC contacts at the same time for charging the electric or hybrid vehicle. During a charging process, only either the direct current charging path or only the alternating current charging path is used.
- the four alternating current contacts which are arranged in the charging socket immediately next to the direct current contacts, remain unused. Due to the simultaneous use of the direct current contacts and the alternating current contacts for direct current charging, which is provided according to the invention, an approximately twice as high current intensity is possible, for example in the previously mentioned type 2 charging plug, which results in a considerable increase. hung the charging power without having to use a fundamentally different type of plug.
- the charging efficiency also increases due to the higher effective cable cross section. Even if the charging power were only increased slightly, the contact resistance would be significantly lower if the direct current contacts and the alternating current contacts were used at the same time and would therefore lead to significantly lower losses during charging.
- the short-circuit device can be controlled in different ways.
- the charging connector is provided with a switch which, in the unactuated state, causes the short-circuiting device to ensure that there is no short circuit between a respective alternating current contact and a respective direct current contact, and produces this short circuit in the actuated state.
- a switch can be actuated in different ways.
- the switch can be actuated by means of a second charging connector connected to the charging connector.
- the switch can basically be designed in different ways.
- the switch is a mechanical switch.
- the system in question is additionally provided with a second charging connector which can be plugged together with the charging connector and which is a switching element has, with which the switch of the charging connector is automatically actuated when plugged together with the second charging connector.
- Poka Yoke design is preferably used in order to prevent such a modified charging connector from being plugged together with conventional charging connectors.
- the Japanese term “Poka Yoke” refers to a principle consisting of several elements, which includes technical precautions or devices for the immediate detection and prevention of errors.
- Poka Yoke is similar to a key and lock principle: the function protected by Poka Yoke can only be activated if a suitable counterpart is used.
- a further advantage is that the charging connector described here on the electric or hybrid vehicle is also compatible without restrictions with charging connectors of conventional charging cables, in particular in accordance with the two standards mentioned above.
- the use of the AC contacts and the DC contacts remains separate, and all usual charging options can still be used.
- the system additionally has a charging station and a charging cable connected to the charging station and carrying the second charging connector on its side facing away from the charging station, the second charging connector, apart from the switching element, according to the US standard SAEJ1772 or the European standard IEC 62196 Type 2 and at the same time has standard alternating current contacts and standard direct current contacts, all of which are supplied with direct current from the charging station via the charging cable.
- the charging connector on the electric or hybrid vehicle can be a conventional charging connector and only the charging connector on the charging cable and the charging electronics unit need to be modified according to the invention.
