Abstract

Het doel van de uitvinding is het laden van loodzuur batterijen als gelegenheidsladen op intervallen van 1 a 2 uur met een laadduur van 5 a 10 minuten of minder dan 10 % van de operationele tijd. Dit laat het gebruik van goedkope loodzuur batterijen toe in elektrische auto's, elektrische vorkliften en andere industriële voertuigen en in stationaire toepassingen om continu operationeel te zijn mits korte regelmatige laadstops van minder dan 10 % van de operationele tijd en om het wisselen van batterijen te vermijden of om te stoppen voor een normale loodzuur batterij laadcyclus van 10 uur.The object of the invention is to charge lead acid batteries as occasional charging at intervals of 1 to 2 hours with a charging time of 5 to 10 minutes or less than 10% of the operational time. This allows the use of inexpensive lead-acid batteries in electric cars, electric forklifts and other industrial vehicles and in stationary applications to be continuously operational with short regular charge stops of less than 10% of the operational time and to avoid or change batteries. to stop for a normal lead-acid battery charge cycle of 10 hours.

Description

Beschrijving: ^ТНООЕ¥СЮК, HET SNELLADEN VAN LOODZUUR BATTERIJEN.Description: ^ ТНООЕ ¥ СЮК, QUICK CHARGE OF LEAD ACID BATTERIES.

Het principe van het systeem is beschreven aan de hand van een voorbeeld van een elektrische vorklift met loodzuur batterijen van 24 volt en 360 Ah of 8.640 Wh capaciteit, met een gemiddelde autonomie van 12 uur en een gemiddeld stroom verbruik van 20 A of een vermogen verbruik van 480 W en met 30 % energiecapaciteit op het einde van de ontlaadcyclus. (zie tekening 1)The principle of the system is described on the basis of an example of an electric fork lift with 24 volt and 360 Ah or 8.640 Wh lead acid batteries, with an average autonomy of 12 hours and an average power consumption of 20 A or a power consumption 480 W and with 30% energy capacity at the end of the discharge cycle. (see drawing 1)

De huidige manier van werken is een stationaire industriële batterij lader, die 220 V wisselstroom omvormt in 24 V gelijkstroom met een stroom van 40 A, resulterend in 9 a 10 uur oplaadtijd. Het laadvermogen os 960 W.The current way of working is a stationary industrial battery charger, which converts 220 V alternating current into 24 V direct current with a current of 40 A, resulting in 9 to 10 hours of charging time. The load capacity os 960 W.

De uitvinding bestaat uit een gelijksoortige stationaire industriële batterij lader maar met laadvermogen dat typisch 6 maal hoger is (5.760 W). The batterij lader converteert de 220 V wisselstroom naar de vereiste 24 V gelijkstroom of beter naar een hogere gelijkstroomspanning (zoals 48 V, 92 V,192v...) om de laadstroom te beperken. The laadstroom op 24 V zou 240 A zijn, op 48 V zou het 120 A zijn ,...De volgende component van de uitvinding is een mobiele batterij lader,die zich op het voertuig bevindt in tegenstelling tot de stationaire industriële batterij lader, (zie tekening 2 ) De functie van de mobiele batterij lader is het converteren van de energie ontvangen van de industriële lader naar de loodzuur batterijen met een maximale stroom van 25 A of maximaal vermogen van 600 W, hetgeen een lage en aanvaardbare laadstroom is voor de loodzuur batterij. De 25 A of 600 W is meer dan het gemiddelde vermogenverbruik van het voertuig. Dus het houdt de loodzuur batterij altijd bijna volledig geladen . De mobiele batterij lader ontvangt 960 Wh in 10 minuten laadtijd en stuurt de 960 Wh met 25 A of 600 W in 1 uur 36 minuten naar de loodbatterij. Aldus is de mobiele batterij lader 2 uur later klaar voor de volgende batterij lading.The invention consists of a similar stationary industrial battery charger but with a load capacity that is typically 6 times higher (5,760 W). The battery charger converts the 220 V AC to the required 24 V DC or better to a higher DC voltage (such as 48 V, 92 V, 192v ...) to limit the charging current. The charging current at 24 V would be 240 A, at 48 V it would be 120 A, ... The next component of the invention is a mobile battery charger located on the vehicle as opposed to the stationary industrial battery charger, ( see drawing 2) The function of the mobile battery charger is to convert the energy received from the industrial charger to the lead acid batteries with a maximum current of 25 A or maximum power of 600 W, which is a low and acceptable charging current for the lead acid battery. The 25 A or 600 W is more than the average power consumption of the vehicle. So it always keeps the lead-acid battery fully charged. The mobile battery charger receives 960 Wh in 10 minutes charging time and sends the 960 Wh with 25 A or 600 W in 1 hour 36 minutes to the lead battery. The mobile battery charger is thus ready for the next battery charge 2 hours later.

De eerste component van de mobiele batterij lader is een snelladende batterij, typisch een lithium ion batterij ( zoals een lithium titaniumoxide batterij met een ultrasnelle laadtijd en een hoge explosieveiligheid ). De snel oplaadbare batterij levert zijn energie op een gecontroleerde wijze via een dc dc convertor ( gelijkstroom -gelijkstroom convertor) naar de loodzuur batterij. De mobiele batterij lader bevat een logische controller ( plc,...) om de energiestroom te controleren en de componenten te beschermen tegen overstroom ofte hoge temperaturen en om de gebruiker te informeren over de laadvereisten. De energiecapaciteit van de snel oplaadbare batterij in de mobiele batterij lader is in dit voorbeeld 40 Ah bij 48 V of 1.920 Wh of 22 % van de loodzuur batterij capaciteit.The first component of the mobile battery charger is a fast-charging battery, typically a lithium ion battery (such as a lithium titanium oxide battery with an ultra-fast charging time and high explosion protection). The quickly rechargeable battery supplies its energy in a controlled manner via a dc dc converter (direct current / direct current converter) to the lead-acid battery. The mobile battery charger contains a logic controller (plc, ...) to check the energy flow and to protect the components against overcurrent or high temperatures and to inform the user about the charging requirements. In this example, the energy capacity of the quickly rechargeable battery in the mobile battery charger is 40 Ah at 48 V or 1,920 Wh or 22% of the lead-acid battery capacity.
