Hello all the members of the E-S forum.
We are a team of enthusiasts based in Moscow, Russia. Over year ago we established a start-up – Adaptto E-drives Lab. Ltd. - to develop e-drive systems for LEVs.
Presently, we are finalizing our first products (some of you might have read about MaxController in AndreyM build thread viewtopic.php?f=6&t=27911&hilit=andreyM+E+drive
), namely sets of all the necessary electronics to get your vehicle going, and would like to present them to you for your evaluation and valuable feedback as well as advertise them, of course.
Once all the in-house testing is over (in around three weeks) we’ll distribute a number of pre-production prototype sets among the reputable power maniacs of the E-S for beta-testing and independent reviews.
The sets were developed with the goal of creating a complete, integrated, adjustable and reliable solution in mind.
The sets will be composed of:
1. Mini-E or Max-E controller:
2. 2,8” monochrome graphic LCD as standard or a 2,8” full colour transflective display as an option (will be available in July 2012);
*these are the early versions of the case and color display interface – the case will mostly remain the same, but the interface will graphics are revised.
3. Proprietary half-twist throttle with 6 buttons as an option (will be available in July 2012);
4. Fully adjustable BMS (option);
5. DC-DC converter (option)Controllers major features:
Sine wave motor power control & intelligent adapting logics higher efficiency , less heat, silent motor operation, all sorts of protection
Very compact for the power they are pumping through
Display to show you everything from ride statistics and “dynamics” to voltage sag on each cell (should you opt for our BMS) and allow PC-free adjustability for you to play with the settings right on spot
Fully adjustable regen, analogue (not pre-set) regen power control given you use our throttle
Possibility to set range - controller will limit the power to the necessary level
Automatic phase/halls wires combo selection = no pain with finding the right combination just make sure the +&- of the halls are connected right the rest will be done by you but electronically through the menu on the display
Protection motor/controller overheating – there’s a thermosensor the in controller and a thermosensor port to monitor motor’s temperature and manage the power accordingly (first the display will show you an alarm warning that you are reaching a certain temperature and once it gets to high the power will be automatically limited until the motor/controller cools down)
Square wave, and sensorless (besides sine wave (vectored) motor control modes (if halls fail -which shouldn’t happen due to overheating protection - the controller will automatically switch to sensorless mode, so you might not even notice the halls are dead until you start on a hill)
Automatic hibernation of the system in the time you set
Motor and battery health monitor
Integration with BMS – you can monitor your battery or each cell, set LVC/HVC to manage your battery’s ‘life expectancy’
Advanced controller settings:
- adjustable PWM frequency (10-30 KHz) for even better efficiency tune
- halls angle correction
- timing tune
3 fully adjustable power modes allowing you to switch between them by a push of a button and change your power settings, including regen and speed limits
Auxiliary devices connection bus to enable BMS or DC-DC converter control through the display
The throttle will control the power, not the speed of the motor
The whole set will be completely waterproof - for example, the groove where the edges of the display case parts will meet will have a layer of rubber molded in
Prototype's pic, not the best colour combo though, will post more pics of different color combos when all the prototypes arrive next week BMS major features:
For batteries upto 100V & 32 cells in series
BMS will consist of the main board and auxiliary balancing boards for up to 4S6P each with standard JSTXH connectors, so no more pain with rewiring the Li-Po packs
Adjustable overcharge/overdischarge cell cut-off voltages for use on any battery type and
BUS interface between the BMS and controller
LVC compatibility with most of the existing controllers
May also be used without the controller set, but with factory presets at your requestThrottle major features:
Will enable “analogue” regen power management by either turning the throttle away from you or by simply pulling the rear brakes lever
Will have a kick-down to activate max power mode (even when you are in eco mode) without pushing any buttons only by turning the throttle harder
Will have 6 ‘appointable’ buttons DC-DC converter major features:
input voltage 20-100V
output voltage 10-90V
output current 10-25 Amps depending on the input V
voltage and current limits are adjustable through display
These products are mainly addressed to DIYers, so comments/suggestions are welcome.
