Parameter Configuration confusion #18

Open karolgoluch opened 2 years ago

karolgoluch commented 2 years ago

Can the parameters of "Battery current max" and "Battery power max" be explained more? What parameter is used with priority and when?

tsdz2 configuration 2 tsdz2 configuration

Example 1: If I set: Battery current max: 10A Battery power max: 750W

and the motor is 48V, what will be max current?

P=U*I => I=P/U I=750W/48V=15,625A

Will the current be limited to 10A or raised to 15,625A?

Example 2: Battery current max: 18A Battery power max: 250W

Will the current be limited to 5,2A (250W/48V)? Or will the power be raised to 864W (18A*48V)?

Or should this be calculated: if: Battery current max = 12A then: Battery power max = 576W

Between the two parameters, the priority is always the lower value. Example 1: current limit 10A, the power limit changes with voltage, 52V 10A = 520W, 40V 10A = 400W. Example 2: power limit 250W, current limit changes with voltage, 250W / 52V = 4.8A, 250W / 40V = 6.25A.

My advice is to set the parameters in order to have a constant maximum power, independent of the battery charge. Example: Battery power max = 520W (current 520W / 52V = 10A) Battery current max = 13A (power 13A * 40V = 520W) Attention the maximum power of 520W cannot be maintained continuously!

Haloo, i hawe confusion between parameeters „Number of data displayed at lights on“ and „Auto display data with lights on“ I have seted:

You should set number of data displayed at lights on to the number of data fields you are using from the 6 available, set to 1 it will only show the first field

  • „Number of data displayed at lights on“ = 1
  • Data1 is set to 0 – motor temperature
  • „Auto display data with lights on“ – on
  • data 1- 6 all set to numbers from 0 to 8
  • time to display data 1-6 to 50 When i switch lights on i can only see only data 1 = motor temperature, other values dont showed after 5s interval. Shud i let parameter „Number of data displayed at lights on“ blank to see data 1to6 in 5sec sekvence?

Thank you for explain, so this is a data limiter - show data numbers values from data1 to this data number value, not exactly data number to display
