DETAILED DESCRIPTION
The fast charging universal serial bus (e.g. USB Type-C) battery charging system 10 for use with a battery charger (e.g. auto charger) for handling higher power is shown in FIGS. 1, 2, 10, and 11.
The battery charging system 10 comprises:
1) VBUS 12 (e.g. main power line);
2) AND gate 14;
3) switch 16;
4) over voltage and reverse polarity protection 18;
5) controller and undervoltage protection 20;
6) 10V - 15V voltage source 22;
7) 5V voltage source 24;
8) safety switch 26;
9) switch 28; and
10) overtemperature protection.
VBUS
The VBUS 12 is a main power line. High power is provided on VBUS by delivering current directly from the Vehicle DC Power Port through a FET switch that is controlled by a customized USB-C Driver. The customized USB-C Driver communicates with our NOCO Boost Jump-starters, then when confirmed, enables the FET switch allowing power to be delivered for charging.
Overvoltage Protection
The battery charging system 10 can include overvoltage protection 18, for example, in case a user accidentally connects to a 24V plug.
Undervoltage Protect
The battery charging system 10 can also include undervoltage protection 20 from car batteries that have a voltage that is too low. If the car battery 40 drops below 10V, the Auto Charger shuts off.
Reverse Voltage Protection
The battery charging system 10 can include reverse polarity protection 18 from Reverse Car Battery connections.
10-15V Source
The battery charging system 10 can include the ability to switch in a 10-15V Voltage source 22. This is the main charging source for the NOCO Boost Jump- starters. The USB-C Driver will communicate with the Jump-starter to enable this 10- 15V Voltage source 22. Safety Switch
The battery charging system 10 can include a safety switch 26 that will only allow the 10-15V Voltage source 22 to be passed through, if the USB-C driver determines that it is safe to do so.
5V Voltage Source
The battery charging system 10 can include a 5V Voltage Source 24 that is used for enabling and low power on the VBUS 12.
Overtemperature Protection
The battery charging system 10 can include over temperature protection 30 that shuts down power on the VBUS 12, if the temperature is ever detected too high.
Keyed Connector
The battery charging system includes a custom connector arrangement 50 comprising an electrical connector 52 and an electrical port 54, as shown in FIGS. 2, 3,
10, and 11 , configured to allow this Auto charger to only plug into a particular type or brand of jump starter (e.g. NOCO Jump Starter). Specifically, the electrical connector 52 and electrical port 54 are compatible and configured to properly connect and operate in conjunction.
The electrical connector 52 is provided with an oval-shaped configuration, as shown in FIGS. 4 and 5. The electrical connector 52 comprises an oval-shaped outer rim 52A, an oval-shaped recess 52B, and an oval-shaped inner protrusion 52F having an inner oval-shaped recess having electrical conductors, as shown in FIG. 4. The electrical port 54 is provided with an oval-shaped configuration, as shown in FIG. 2. The electrical port 54 comprises an oval-shaped outer rim 54A, an oval-shaped recess 54B, an oval-shaped inner protrusion 54C, an oval-shaped inner recess 54D, and an oval-shaped protrusion 54E having electrical conductors.
