Proper connectors - the must to avoid problems in the future
The photo shows the EVBike connectors (at the motor side) that were burnt during a period of use. The reason of such a situation is the dirt on the terminals and the improper connection. During high current peaks, the connectors overheat and the resistance of such connectors is increasing. The more the resistance is increasing, the more heat is emitted. As a result the connector may become burnt completely.
Make your connections proper. Keep your connectors clean.
This EVBike is a prototype using the new central motor power assistant. The new central motor will be available in spring 2014. We will give the updates at the GWL Blog, when this new product is ready for mass orders.
All EVBike kits are factory-equipped with 4-pin connectors, which are able to operate with high current from the EVBike lithium batteries. In case your connector is broken or if you are thinking of making your own strong EVbike battery from small LiFePo4 cells, you can buy spare MC12-4P connectors at EV-POWER.EU.
Examples of custom battery packs for hi-power EV-BIKE conversions:
Did you know that both EVBAT36V7A and EVBAT36V10A batteries have integrated balancing circuit? If you keep your standard ev-bike charger connected over night (green LED ON), the charger will balance weaker cells up to the level of the strongest ones in the battery with a low current. If the performance of your battery is not as brand new, it is recommended to proceed balancing once per 10 rides. Balancing is also recommended when the battery was not used for several months, for example after winter. (Balancing of a brand new battery is not necessary and might actually shorten its lifetime.)
EVBike innovation: Speedict Mars - digital datalogger
Speedict Mars is the world’s first electric bike logger features live view, system setting, and parameters turning on Android’s smart device via Bluetooth protocol.
The Mars measures and records Speed, Current, Voltage, Cadence and Temperature over time, then use these measurement to calculate the maximum Power (Watt), battery consumption (mAh). Real-time information as to live and peak Current, live and used Voltage, Current and maximum Power (Watt), as well as existing and consumed Capacity (mAh) is transmitting using Bluetooth technology. Biker can use their cell-phone to read these data in real-time for their pleasure or to fine-tune their power system.
The Mars can save up to 12 hours of information. Bikers can download their logged data to their Android device and manage the data and performance charts in offline mode.
