With the increasing sales of new energy vehicles (HV/EV), C-NCAP 2021 also paid special attention to the safety of new energy vehicles. Experts in vehicle safety research and development have also designed their own unique power-off curves after T0. This requires reasonable monitoring of the vehicle's V1, V2, VB, insulation, and residual power during the crash test. After all, the voltage of most new energy vehicles is approaching 400V! So don't touch it! Unless, you have the following equipment:
1. Insulation tester RES-1000A + high voltage connection box HV-BOX:
Insulation meter RES-1000A is built by the Jipu team. From the perspective of safety, it adopts nylon shell, banana-head high-voltage plug, and full 1500V internal isolation to achieve VB measurement after collision in C-NCAP 2021, FMVSS305, ECE R94, and residual power measurement. Insulation resistance measurement before and after collision. Internal program design, full parameter setting, fool-style automatic measurement, data storage, alarm function. HV-BOX starts from the safety of the test site. Engineers can directly connect the high-voltage junction box to the high-voltage circuit, retaining the insulation type of the high-voltage circuit to the greatest extent, and at the same time safely and conveniently lead out the high-voltage measurement port. Various interface types can be arbitrarily specified. . Including a set of 4mm banana jack sockets for direct connection with RES-1000A. At the same time, an insulation simulator Iso-Simulator can be provided to test the vehicle insulation alarm function before the test.
2. High voltage sensor JHVS-1000 (three-channel version JHVST-1000 is also available) + high current sensor JCS15D (maximum 15mm wire diameter) or JCS35D (maximum 35mm wire diameter):

2. High voltage sensor JHVS-1000 (three-channel version JHVST-1000 is also available) + high current sensor JCS15D (maximum 15mm wire diameter) or JCS35D (maximum 35mm wire diameter):
High-voltage sensors and high-current sensors provide a high-voltage measurement transient signal acquisition program. The high voltage sensor adopts 1500V isolation design inside, and the frequency response is above 40KHZ. Its 4mm banana head design can be directly connected to the high voltage junction box HV-BOX (the banana heads can be connected in multiple stages!), which is very convenient! The high-current sensor adopts the Hall principle, and the frequency response is as high as 100KHZ; its open design is very convenient for measurement and installation!
3. Low-voltage monitoring (car battery power-off measurement) sensor JHVS-50+ control signal monitoring sensor JCS06D.
The high-voltage logic control of a vehicle is often closely related to whether the low-voltage battery on the vehicle is powered off. During the collision test, whether the on-board battery has been powered off, JHVS-50 will tell you the answer in real time; in addition, the ECU will issue instructions to the multi-switch during the collision. The current sensor JCS06D is an ideal choice if the instructions are timely and correct.
If you think that JHVS-50 and JCS06D have only this ability, then they are underestimated. In fact, they are not only exquisite in appearance, but also truly stable, fast and accurate! So, use your imagination!
Jebool Technology provides annual calibration services and lifetime technical support for the above electrical measuring equipment!
Please pay attention to high voltage safety during the test!
