FAQ

The battery is designed and produced by VELOKS in Denmark. Only new quality cells from Panasonic, LG or Samsung are used. For 1.5 kWh and 2.3 kWh 18650 lithium cells are used, and for 3.3 kWh , 4.1 kWh & 5.0 kWh 21700 lithium cells are used.

The batteries consist of 16 “cells blocks” in series, i.e. 60 V nominal. Each “cell block” consist of either 6, 12, 18 or 21 matched cells in parallel. The cells are connected via 100% pure nickel strips that are spot welded to the cells. To ensure equal current load to each individual cells, the main power wires are connected to the cells blocks by means of a solid cobber bus, and “cells blocks” are interconnected in series between each individual cell by nickel strips. The battery box is a sandwich construction that is made of carbon fiber as the outside layers, and fiber glass as inside layers. This ensures a very strong and stiff, yet crack resistant box, which is electrical isolated.

The battery is protected by means of a battery management system (BMS). The BMS will monitor the battery and cell voltage, the battery temperature, the charge & regen current and the discharge current and protect the battery by turning if off if appropriate. When charging the battery to 100%, the “cells blocks” are balanced (i.e. have identical voltage)

The VELOKS MK3 trike support battery capacities from 1.5 kWh to 5 kWh, and such batteries have a relatively high weight from 6 kg to 19 kg. By placing this weight at the center under the seat, it will improve the stability of the trike (lower center of gravity). It also “hides” the large battery from sight and makes the trikes look better. Thirdly, the battery has 4 mounting points, and can be easily removed by opening the two snap clips and sliding out the battery. This is handy if you need to charge the battery inside due to lack of external power, or to ensure that the battery starts with maximum capacity when it is very cold outside.

The battery box contains the lithium cells, the motor controller and the battery management system. The total weight of the battery box is for 1.5 kWh 9 Kg, 2.3 kWh = 12 Kg and for 3.2 kWh = 15 Kg, 4,1 = 18 Kg, and 5.0 kWh = 21,5 Kg

Depends on three things, the state of the battery, charger current, and the installed battery capacity. 

Using the standard charger (8A) , the 1.5 kWh battery, charging an empty battery to 100%, will take approx 4 hours.

For the 2.3 kWh approx 6 hours, for the 3.3 kWh approx 8 hours, for the 4.1 kWh approx 10 hours, and for the 5.0 kWh approx 12 hours.

The table below list charging times to fully charge an empty battery using the charges available.

In practice the above to times will be shorter, as the battery rarely is fully discharged (empty)
