The JLD505

The JLD505 module consists of a single two-layer printed circuit board mounted in a
Modice Cinch LE weatherproof enclosure.
This module is compatible with the Arduino Uno multicrontroller board and uses the
Arduino Integrated Development Environment for programming.
The heart of the module is an ATMEGA328P-AU 16 MHz multicontroller. The highperformance Atmel picoPower 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory with read-while-write capabilities, 1024B EEPROM, 2KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial
programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-
channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages),
programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts.
By executing powerful instructions in a single clock cycle, the device achieves

ChaDeMo testing at FastNed fail

Only 10 Km from where I am there is an ChaDeMo charge station owned by FastNed. With the battery pack loaded into the Land Rover I headed to the charging station.

The first test gave some result but no charging took place. After 4 seconds the charging stopped.

ChaDeMo project continued

One year ago I started with the ChaDeMo project. I build a test battery pack but wasn’t able to get my hands on a JLD505. The JLD505 was developed in 2015 and sold by EVTV. Unfortunately they discontinued the JLD505. A few weeks ago I was able to buy an used JLD505. Unfortunately it is modified to be used in a Zero motorcycle.

After some modification I was able to connect the JLD505 to my test pack.

ChaDeMO charge project

The Lotus Elise ECE EV conversion is based on the AC-150 Gen 2 from AC Propulsion. Unfortunately the AC-150 Gen 2 is developed before any charging standard was published. Charging is managed by de PEU (Power Electronics Unit) and is limited to 20KW (240V/83A one phase). 83A on one phase is way more than a standard household wall outlet in Europe provides. Home charging on a standard 240V wall outlet is limited to 16A. Public charging using the Mennekes connector is also limited to 16A (one phase). In Holland most modern houses have a 3x25A powerline which can often be upgraded to 3x35A without replacing de powerlines to the power company . 35A is better than 16A but it isn’t real fast charging.

An alternative would be public DC fast charging, But which standard should be used in a DIY install. ChaDeMo is getting popular in Holland. Currently (begin 2016) there are over 100 ChadeMo fast charge stations. So ChaDeMO would be the wiser choise. Currently there are a few suppliers of ChaDeMo interface which work on any EV. EVWest developed the jld-505 and Lithium Balance sells the LiBal Fast Charge interface for €1000,- or more.

For both interfaces the challenge would be how to integrate them into my EV. I think it might be easier to develop a custom interface based on the ChaDeMO standard and the information available on internet.
