Super Soco

The Super Soco TC Max is a 5000 Watt electric motorcycle. One of the first affordable electric motorcycles with reasonable range and performance. These pages will cover my attempts to reverse engineer and maintain this motorcycle.

After adding some stickers the first small project was to rewire the UK spec headlight switch. The wires for the headlight are permanently joined in the switch so the switch was removed and re-soldered to the switch terminals. The switch now toggles between lights on and auto lights... Much better.

Now lets get into what's planned for bigger improvements... The battery is a 20 cell ATL lithium ferrite type. Lithium ferrite is a good chemistry to use for low cost and reliability. They also have no cobalt in them. These are the same type that Tesla use in their Chinese made standard range Model 3. The down side is they don't have the energy density of lithium ion. So the plan is to build a new upgrade battery using 18650 lithium ion cells. Which hopefully should have 25% more capacity and 40% less weight! Please visit the TC Max battery page to find out how I get on....

TC Max Battery Upgrade

The standard charger that came with my bike is only capable of charging at 5 Amps. This means charge times can take up to 8 hours depending on state of charge. On the TC Max battery page I will investigate the possible alternatives with the goal of reducing charge time without too much cost...

Although electric vehicles require minimal maintenance they do require some. Check out the TC Max maintenance page for info on belt tension, brake servicing and other

TC Max Programming

The Super Soco TC Max has a motor controller made by the well known Chinese company Golden Motor. The parameters of which are easily modified using a programming cable and PC. In this article I will describe how to enable regenerative braking on the TC Max. The same principles apply to adjusting all other parameters in the controller firmware. Be careful as it's possible to damage the motor and controller.

The only hardware required to program the motor controller are an allen key, a programming cable and a PC. 

Firstly the battery must be disconnected. Switch the breaker off and unplug the battery from the bike. Failure to do so could result in damage to hardware. For safety purposes you should make a habit of always disconnecting the battery when working on your bike.

To access the controller programming port both top and bottom right hand fairing panels must be removed. In order to remove the bottom panel the foot peg must also be removed.

Once the panels are removed the six pin programming port can be found at the front of the controller under a rubber bung.

Plug the programming cable into the port ensuring it's pushed all the way in and the retaining clip is engaged.

Plug the other end into your PC then start the programming software.

Select the com port you plugged the cable into.

Then click the connect button. The standard parameters should appear.

Click the export button and save the standard parameters to a file. Save the file to a safe place in case you need to return the settings to standard.

To enable regenerative braking look under the heading "EBS func setting" and select enable. The setting "EBS rev-charging current" is set to 80 by default this must be reduced to a value of 28. This should give you enough regenerative braking but won't cause an over current error on the battery's BMS. Failure to do this could possibly lock the back wheel or damage your bike.

Once you're happy with the settings press the download button to save them to the controller.

Click the upload button to check your parameters have been saved correctly. Then take your bike for a test ride.

The 12V signal for the regenerative brake is already wired to the brake light. So as soon as you pull the brake lever in enough for the brake light to come on the regen will start. There is a slight delay before it starts and also when it releases. Looking at the data from my ANT BMS you can see that it's charging the battery at a current of 9.2 Amps.
